2. License Grants and Conditions
--------------------------------
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or
as part of a Larger Work; and
(b) under Patent Claims of such Contributor to make, use, sell, offer
for sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
(a) for any code that a Contributor has removed from Covered Software;
or
(b) for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
(c) under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code
Form by reasonable means in a timely manner, at a charge no more
than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter
the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,

<!-- ABOUT THE PROJECT -->
## About The Project
MiniZinc is a free and open-source constraint modeling language.
You can use MiniZinc to model constraint satisfaction and optimisation problems
in a high-level, solver-independent way, taking advantage of a large library of
pre-defined constraints. Your model is then compiled into FlatZinc, a solver
input language that is understood by a wide range of solvers.
MiniZinc is developed at Monash University in collaboration with Data61
Decision Sciences.
<!-- GETTING STARTED -->
## Getting Started
To get a MiniZinc up and running follow these simple steps.
### Installation
The recommended way to install _MiniZinc_ is by the use of the bundled binary
packages. These packages are available for machines running Linux, Mac, and
Windows.
The latest release can be found on [the MiniZinc
website](http://www.minizinc.org/software.html).
### Usage
Once the MiniZinc bundle is installed on your machine, you can start expressing
and solving discrete optimisation problems. The following code segment shows a
MiniZinc model for the well known n-queens problem.
```minizinc
int: n = 8; % The number of queens.
array [1..n] of var 1..n: q;
include "alldifferent.mzn";
constraint alldifferent(q);
constraint alldifferent(i in 1..n)(q[i] + i);
constraint alldifferent(i in 1..n)(q[i] - i);
```
You have two easy options to solve this model:
- In the MiniZincIDE: Select your preferred solver and press the "Run" button.
- With the `minizinc` executable available on your path: run `minizinc --solver gecode nqueens.mzn`.
_For more example MiniZinc models and more information about working with
MiniZinc, please refer to our
[Documentation](https://www.minizinc.org/doc-latest/)_
<!-- BUILDING INSTRUCTIONS -->
## Building
The following instructions will help you compile the MiniZinc compiler. Note
that this repository does not include the IDE, findMUS, or any solvers that are
part of the MiniZinc project. These can be found in the following repositories:
- [MiniZincIDE](https://github.com/MiniZinc/MiniZincIDE)
- [Gecode](https://github.com/Gecode/gecode)
- [Chuffed](https://github.com/chuffed/chuffed)
### Prerequisites
- [CMake](https://cmake.org/) (>=3.4)
- A recent C++ compiler - Compilation is tested with recent versions of Clang,
GCC, and Microsoft Visual C++.
- (optional) [Bison](https://www.gnu.org/software/bison/) (>=3.4) and
[Flex](https://github.com/westes/flex) (>=2.5) - To make changes to the
MiniZinc lexer or parser.
- (optional) [Gecode](https://www.gecode.org/) - To compile the internal Gecode
solver interface (included in the MiniZinc bundle)
- (optional) [Coin OR's CBC](https://www.coin-or.org/) - To compile the
internal CBC solver interface (included in the MiniZinc bundle)
- (optional) Proprietary solver headers
([CPLEX](https://www.ibm.com/analytics/cplex-optimizer),
[Gurobi](https://www.gurobi.com/), [SCIP](https://www.scipopt.org/),
[Xpress](https://www.fico.com/)) - To load these solvers at runtime (included
in the MiniZinc bundle)
### Compilation
The MiniZinc compiler is compiled as a CMake project. CMake's [User Interaction
Guide](https://cmake.org/cmake/help/latest/guide/user-interaction/index.html)
can provide you with a quick introduction to compiling CMake projects. The
following CMake variables can be used in the MiniZinc project to instruct the
compilation behaviour:
| Variable | Default | Description |
|----------------------------------------------|---------|-------------------------------------------------------------|
| CMAKE_BUILD_TYPE | Release | Build type of single-configuration generators. |
| CMAKE_INSTALL_PREFIX | | Install directory used by `--target install`. |
| CMAKE_POSITION_INDEPENDENT_CODE | TRUE | Whether to create a position-independent targets |
| **<solver_name>**_ROOT | | Additional directory to look for **<solver_name>** |
| CMAKE_DISABLE_FIND_PACKAGE_**<solver_name>** | FALSE | Disable compilation of **<solver_name>**'s solver interface |
| USE_PROPRIETARY | FALSE | Allow static linking of proprietary solvers |
| **<Gurobi/CPlex>**_PLUGIN | TRUE | Load solver at runtime (instead of static compilation) |
Possible values for **<solver_name>** are `CPlex`, `Geas`, `Gecode`, `Gurobi`,
`OsiCBC`, `SCIP`, and `Xpress`.
<!-- TESTING INSTRUCTIONS -->
## Testing
The correctness of the MiniZinc compiler is tested using a
[PyTest](https://docs.pytest.org/en/stable/) test suite. Instruction on how to
run the test suite and how to add new tests can be found
[here](https://github.com/MiniZinc/libminizinc/tree/master/tests)

Using Creative Commons Public Licenses
Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.
Considerations for licensors: Our public licenses are
intended for use by those authorized to give the public
permission to use material in ways otherwise restricted by
copyright and certain other rights. Our licenses are
irrevocable. Licensors should read and understand the terms
and conditions of the license they choose before applying it.
Licensors should also secure all rights necessary before
applying our licenses so that the public can reuse the
material as expected. Licensors should clearly mark any
material not subject to the license. This includes other CC-
licensed material, or material used under an exception or
limitation to copyright. More considerations for licensors:

Considerations for the public: By using one of our public
licenses, a licensor grants the public permission to use the
licensed material under specified terms and conditions. If
the licensor's permission is not necessary for any reason--for
example, because of any applicable exception or limitation to
copyright--then that use is not regulated by the license. Our
licenses grant only permissions under copyright and certain
other rights that a licensor has authority to grant. Use of
the licensed material may still be restricted for other
reasons, including because others have copyright or other
rights in the material. A licensor may make special requests,
such as asking that all changes be marked or described.
Although not required by our licenses, you are encouraged to
respect those requests where reasonable. More considerations

Creative Commons Attribution-NoDerivatives 4.0 International Public
License
By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NoDerivatives 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your
acceptance of these terms and conditions, and the Licensor grants You
such rights in consideration of benefits the Licensor receives from
making the Licensed Material available under these terms and
conditions.
Section 1 -- Definitions.
a. Adapted Material means material subject to Copyright and Similar
Rights that is derived from or based upon the Licensed Material
and in which the Licensed Material is translated, altered,
arranged, transformed, or otherwise modified in a manner requiring
permission under the Copyright and Similar Rights held by the
Licensor. For purposes of this Public License, where the Licensed
Material is a musical work, performance, or sound recording,
Adapted Material is always produced where the Licensed Material is
synched in timed relation with a moving image.
b. Copyright and Similar Rights means copyright and/or similar rights
closely related to copyright including, without limitation,
performance, broadcast, sound recording, and Sui Generis Database
Rights, without regard to how the rights are labeled or
categorized. For purposes of this Public License, the rights
specified in Section 2(b)(1)-(2) are not Copyright and Similar
Rights.
c. Effective Technological Measures means those measures that, in the
absence of proper authority, may not be circumvented under laws
fulfilling obligations under Article 11 of the WIPO Copyright
Treaty adopted on December 20, 1996, and/or similar international
agreements.
d. Exceptions and Limitations means fair use, fair dealing, and/or
any other exception or limitation to Copyright and Similar Rights
that applies to Your use of the Licensed Material.
e. Licensed Material means the artistic or literary work, database,
or other material to which the Licensor applied this Public
License.
f. Licensed Rights means the rights granted to You subject to the
terms and conditions of this Public License, which are limited to
all Copyright and Similar Rights that apply to Your use of the
Licensed Material and that the Licensor has authority to license.
g. Licensor means the individual(s) or entity(ies) granting rights
under this Public License.
h. Share means to provide material to the public by any means or
process that requires permission under the Licensed Rights, such
as reproduction, public display, public performance, distribution,
dissemination, communication, or importation, and to make material
available to the public including in ways that members of the
public may access the material from a place and at a time
individually chosen by them.
i. Sui Generis Database Rights means rights other than copyright
resulting from Directive 96/9/EC of the European Parliament and of
the Council of 11 March 1996 on the legal protection of databases,
as amended and/or succeeded, as well as other essentially
equivalent rights anywhere in the world.
j. You means the individual or entity exercising the Licensed Rights
under this Public License. Your has a corresponding meaning.
Section 2 -- Scope.
a. License grant.
1. Subject to the terms and conditions of this Public License,
the Licensor hereby grants You a worldwide, royalty-free,
non-sublicensable, non-exclusive, irrevocable license to
exercise the Licensed Rights in the Licensed Material to:
a. reproduce and Share the Licensed Material, in whole or
in part; and
b. produce and reproduce, but not Share, Adapted Material.
2. Exceptions and Limitations. For the avoidance of doubt, where
Exceptions and Limitations apply to Your use, this Public
License does not apply, and You do not need to comply with
its terms and conditions.
3. Term. The term of this Public License is specified in Section
6(a).
4. Media and formats; technical modifications allowed. The
Licensor authorizes You to exercise the Licensed Rights in
all media and formats whether now known or hereafter created,
and to make technical modifications necessary to do so. The
Licensor waives and/or agrees not to assert any right or
authority to forbid You from making technical modifications
necessary to exercise the Licensed Rights, including
technical modifications necessary to circumvent Effective
Technological Measures. For purposes of this Public License,
simply making modifications authorized by this Section 2(a)
(4) never produces Adapted Material.
5. Downstream recipients.
a. Offer from the Licensor -- Licensed Material. Every
recipient of the Licensed Material automatically
receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this
Public License.
b. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.
6. No endorsement. Nothing in this Public License constitutes or
may be construed as permission to assert or imply that You
are, or that Your use of the Licensed Material is, connected
with, or sponsored, endorsed, or granted official status by,
the Licensor or others designated to receive attribution as
provided in Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not
licensed under this Public License, nor are publicity,
privacy, and/or other similar personality rights; however, to
the extent possible, the Licensor waives and/or agrees not to
assert any such rights held by the Licensor to the limited
extent necessary to allow You to exercise the Licensed
Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
Public License.
3. To the extent possible, the Licensor waives any right to
collect royalties from You for the exercise of the Licensed
Rights, whether directly or through a collecting society
under any voluntary or waivable statutory or compulsory
licensing scheme. In all other cases the Licensor expressly
reserves any right to collect such royalties.
Section 3 -- License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.
a. Attribution.
1. If You Share the Licensed Material, You must:
a. retain the following if it is supplied by the Licensor
with the Licensed Material:
i. identification of the creator(s) of the Licensed
Material and any others designated to receive
attribution, in any reasonable manner requested by
the Licensor (including by pseudonym if
designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of
warranties;
v. a URI or hyperlink to the Licensed Material to the
extent reasonably practicable;
b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and
c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.
For the avoidance of doubt, You do not have permission under
this Public License to Share Adapted Material.
2. You may satisfy the conditions in Section 3(a)(1) in any
reasonable manner based on the medium, means, and context in
which You Share the Licensed Material. For example, it may be
reasonable to satisfy the conditions by providing a URI or
hyperlink to a resource that includes the required
information.
3. If requested by the Licensor, You must remove any of the
information required by Section 3(a)(1)(A) to the extent
reasonably practicable.

to extract, reuse, reproduce, and Share all or a substantial
portion of the contents of the database, provided You do not Share
Adapted Material;
b. if You include all or a substantial portion of the database
contents in a database in which You have Sui Generis Database
Rights, then the database in which You have Sui Generis Database
Rights (but not its individual contents) is Adapted Material; and
c. You must comply with the conditions in Section 3(a) if You Share
all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR

ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
above shall be interpreted in a manner that, to the extent
possible, most closely approximates an absolute disclaimer and
waiver of all liability.
Section 6 -- Term and Termination.
a. This Public License applies for the term of the Copyright and
Similar Rights licensed here. However, if You fail to comply with
this Public License, then Your rights under this Public License
terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
it is cured within 30 days of Your discovery of the
violation; or
2. upon express reinstatement by the Licensor.
For the avoidance of doubt, this Section 6(b) does not affect any
right the Licensor may have to seek remedies for Your violations
of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
Licensed Material under separate terms or conditions or stop
distributing the Licensed Material at any time; however, doing so
will not terminate this Public License.

conditions on any use of the Licensed Material that could lawfully
be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
deemed unenforceable, it shall be automatically reformed to the
minimum extent necessary to make it enforceable. If the provision
cannot be reformed, it shall be severed from this Public License
without affecting the enforceability of the remaining terms and
conditions.
c. No term or condition of this Public License will be waived and no
failure to comply consented to unless expressly agreed to by the

This directory contains the MiniZinc documentation.
### Building the docs ###
You need the following tools to build the documentation:
* Python 3
* GNU make
* Sphinx version 1.8.0. Install it using the command
`pip install git+https://github.com/sphinx-doc/sphinx`
* Sphinx Read The Docs html theme. Install it using the command
`pip install sphinx_rtd_theme`
* If you want to build the PDF documentation, you also need a LaTeX
distribution that includes xetex, and install the following fonts: Charter,
Lato and Inconsolata.
To build the HTML documentation, simply run `make html`. To build the PDF, run `make latexpdf`.
### Including the MiniZinc library reference documentation ###
The reference documentation for the MiniZinc library can be generated
automatically from the source code. Then run the following command:
``mzn2doc --rst-output --include-stdlib --output-base en ../share/minizinc/std/globals.mzn``

MiniZinc中的有效建模实践
=========================================
对同一个问题,几乎总是存在多种方式来建模。其中一些产生的模型可以很有效地求解,另外一些则不是。通常情况下,我们很难提前判断哪个模型是对解决一个特定的问题最有效的。事实上,这或许十分依赖于我们使用的底层求解器。在这一章中,我们专注于建模实践,来避免产生模型的过程和产生的模型低效。
变量界限
---------------
.. index::
single: variable; bound
有限域传播器是MiniZinc所针对的求解器中的核心类型。在当其所涉及到的变量的界限越紧凑时此传播器越有效。
它也会当问题含有会取很大整型数值的子表达式时表现得很差,因为它们可能会隐式地限制整型变量的大小。
.. literalinclude:: examples/grocery.mzn
:language: minizinc
:name: ex-grocery
:caption: 没有无界整数的模型 (:download:`grocery.mzn <examples/grocery.mzn>`).
:numref:`ex-grocery` 中的中的杂货店问题要找寻4个物品使得它们的价格加起来有7.11元并且乘起来也有7.11元。变量被声明为无界限。运行
.. code-block:: bash
$ minizinc --solver g12fd grocery.mzn
得到
.. code-block:: none
=====UNSATISFIABLE=====
% /tmp/mznfile85EWzj.fzn:11: warning: model inconsistency detected before search.
这是因为乘法中的中间表达式的类型也会是 :mzn:`var int` ,也会被求解器给一个默认的界限 :math:`-1,000,000 \dots 1,000,000` 。但是这个范围太小了以至于不能承载住中间表达式所可能取的值。
更改模型使得初始变量都被声明为拥有更紧致的界限
.. code-block:: minizinc
var 1..711: item1;
var 1..711: item2;
var 1..711: item3;
var 1..711: item4;
我们得到一个更好的模型因为现在MiniZinc可以推断出中间表达式的界限并且使用此界限而不是默认的界限。在做此更改后求解模型我们得到
.. code-block:: none
{120,125,150,316}
----------
注意,就算是改善的模型也可能对于某些求解器来说会很难解决。
运行
.. code-block:: bash
$ minizinc --solver g12lazy grocery.mzn
不能得到任何结果,因为求解器给中间产生的变量创建了巨大的表示。
.. defblock:: 给变量加界限
.. index::
single: variable; bound
在模型中要尽量使用有界限的变量。当使用 :mzn:`let` 声明来引进新的变量时,始终尽量给它们定义正确的和紧凑的界限。这会使得你的模型更有效率,避免出现意外溢出的可能性。
一个例外是当你引进一个新的变量然后立刻定义它等于一个表达式通常MiniZinc都可以从此表达式推断出此变量有效的界限。
有效的生成元
--------------------
.. index::
single: generator
想象下我们想要计算在一个图中出现的三角形的个数( :math:`K_3` 子图)。
假设此图由一个邻接矩阵定义:如果点$i$和$j$邻接,则 :mzn:`adj[i,j]` 为真。
我们或许可以写成
.. code-block:: minizinc
int: count = sum ([ 1 | i,j,k in NODES where i < j /\ j < k
/\ adj[i,j] /\ adj[i,k] /\ adj[j,k]]);
这当然是对的,但是它检查了所有点可能组成的三元组。
如果此图是稀疏的,在意识到一旦我们选择了 :mzn:`i`:mzn:`j` ,就可以进行一些测试之后,我们可以做得更好。
.. code-block:: minizinc
int: count = sum ([ 1 | i,j in NODES where i < j /\ adj[i,j],
k in NODES where j < k /\ adj[i,k] /\ adj[j,k]]);
你可以使用内建 :mzn:`trace` :index:`函数 <trace>` 来帮助决定在生成元内发生了什么。
.. defblock:: 追踪
函数 :mzn:`trace(s,e)` 在对表达式 :mzn:`e` 求值并返回它的值之前就输出字符串 :mzn:`s` 。它可以在任何情境下使用。
例如,我们可以查看在两种计算方式下的内部循环中分别进行了多少次测试。
.. literalinclude:: examples/count1.mzn
:language: minizinc
:lines: 8-15
得到输出:
.. code-block:: none
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
----------
表示内部循环进行了64次
.. literalinclude:: examples/count2.mzn
:language: minizinc
:lines: 13-14
得到输出
.. code-block:: none
++++++++++++++++
----------
表示内部循环进行了16次。
注意你可以在 :mzn:`trace` 中使用单独的字符串来帮助你理解模型创建过程中发生了什么。
.. literalinclude:: examples/count3.mzn
:language: minizinc
:lines: 13-15
会输出在计算过程中找到的每个三角形。得到输出
.. code-block:: none
(1,2,3)
----------
我们要承认这里我们有一点点作弊: 在某些情况下, MiniZinc编译器实际上会把 ``where`` 从句中的参数自动重新排序, 所以他们会尽快地被计算。在这种情况下, 加入 ``trace`` 函数实际上 *阻止* 了这种优化. 一般来说, 通过分离 ``where`` 从句把它们摆到尽量接近生成元, 这其实是一个很好的主意来帮助编译器运作正常。
冗余约束
---------------------
.. index::
single: constraint; redundant
模型的形式会影响约束求解器求解它的效率。
在很多情况下加入冗余约束,即被现有的模型逻辑上隐含的约束,可能会让求解器在更早时候产生更多可用的信息从而提高找寻解的搜索效率。
回顾下第 :ref:`sec-complex` 节中的魔术串问题。
运行 :mzn:`n = 16` 时的模型:
.. code-block:: bash
$ minizinc --all-solutions --statistics magic-series.mzn -D "n=16;"
:mzn:`n = 16`
.. code-block:: none
s = [12, 2, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0];
----------
==========
统计数据显示需要有89个失败。
我们可以在模型中加入冗余约束。由于序列中的每个数字是用来计算某一个数字出现的次数,我们知道它们的和肯定是 :mzn:`n`
类似地,由于这个序列是魔术的,我们知道 :mzn:`s[i] * i` 的和肯定也是 :mzn:`n`
使用如下方式把这些约束加入我们的模型 :numref:`ex-magic-series2`.
.. literalinclude:: examples/magic-series2.mzn
:language: minizinc
:name: ex-magic-series2
:caption: 使用冗余约束求解魔术串问题模型 (:download:`magic-series2.mzn <examples/magic-series2.mzn>`).
像之前那样求解同一个问题
.. code-block:: bash
$ minizinc --all-solutions --statistics magic-series2.mzn -D "n=16;"
产生了同样的输出。但是统计显示只搜索了13个决策点。这些冗余约束使得求解器更早地去剪枝。
模型选择
-----------------
在MiniZinc中有很多方式去给同一个问题建模尽管其中有些模型或许会比另外的一些模型更自然。
不同的模型或许会产生不同的求解效率。更糟糕的是,在不同的求解后端中,不同的模型或许会更好或更差。
但是,我们还是可以给出一些关于普遍情况下产生更好的模型的指导:
.. defblock:: 模型之间的选择
一个好的模型倾向于有以下特征
- 更少量的变量,或者至少是更少量的没有被其他变量功能上定义的变量。
- 更小的变量定义域范围
- 模型的约束定义更简洁或者直接
- 尽可能地使用全局约束
实际情况中,所有这些都需要通过检查这个模型的搜索到底多有效率来断定模型好坏。通常除了用实验之外,我们很难判断搜索是否高效。
观察如下问题我们要找寻1到 :math:`n`:math:`n` 个数字的排列使得相邻数字的差值也形成一个1到 :math:`n` 的排列。
:numref:`ex-allint` 中给出了一个用直观的方式来建模此问题的模型。注意变量 :mzn:`u` 被变量 :mzn:`x` 功能性定义。所以最差情况下的搜索空间是 :math:`n^n`
.. literalinclude:: examples/allinterval.mzn
:language: minizinc
:name: ex-allint
:caption: 对于CSPlib ``prob007`` 所有间隔系列问题的模型 (:download:`allinterval.mzn <examples/allinterval.mzn>`).
在这个模型中,数组 :mzn:`x` 代表 :mzn:`n` 个数字的排序。约束自然地可用 :mzn:`alldifferent` 来表示。
求解模型
.. code-block:: bash
$ minizinc --solver g12fd --all-solutions --statistics allinterval.mzn -D "n=10;"
在84598个决策点和3秒的时间内找到了所有的解。
另外一个模型是使用数组 :mzn:`y` ,其中 :mzn:`y[i]` 代表数字 :mzn:`i` 在序列中的位置。
我们同时也使用变量 :mzn:`v` 来建模表示差的位置。 :mzn:`v[i]` 表示了绝对值差 :mzn:`i` 在序列出现的位置。
如果 :mzn:`y[i]`:mzn:`y[j]` 差别为一,其中 :mzn:`j > i` ,则代表了它们的位置是相邻的。所以 :mzn:`v[j-i]` 被约束为两个位置中最早的那个。
我们可以给这个模型加入两个冗余约束:由于我们知道差值 :mzn:`n-1` 肯定会产生我们就可以推断出1和 :mzn:`n` 的位置必须是相邻的 :mzn:`abs( y[1] - y[n] ) = 1` 。同时也告诉我们差值 :mzn:`n-1` 的位置就是在 :mzn:`y[1]`:mzn:`y[n]` 中的最早的那个位置,即 :mzn:`v[n-1] = min(y[1], y[n])` 。有了这些之后,我们可以建模此问题为:numref:`ex-allint2`
输出语句从位置数组 :mzn:`y` 里重现了原本的序列 :mzn:`x`
.. literalinclude:: examples/allinterval2.mzn
:language: minizinc
:name: ex-allint2
:caption: CSPlib中全区间序列问题 ``prob007`` 的一个逆向模型。 (:download:`allinterval2.mzn <examples/allinterval2.mzn>`).
逆向模型跟初始模型有同样的变量和定义域大小。但是相对于给变量 :mzn:`x`:mzn:`u` 的关系建模,逆向模型使用了一个更加非直接的方式来给变量 :mzn:`y`:mzn:`v` 的关系建模。所以我们或许期望初始模型更好些。
命令
.. code-block:: bash
$ minizinc --solver g12fd --all-solutions --statistics allinterval2.mzn -D "n=10;"
在75536个决策点和18秒内找到了所有的解。
有趣的是,尽管这个模型不是简洁的,在变量 :mzn:`y` 上搜索比在变量 :mzn:`x` 上搜索更加有效率。
简洁的缺乏意味着尽管搜索需要更少的决策点,但是在时间上实质上会更慢。
.. _sec-multiple-modelling-and-channels:
多重建模和连通
-------------------------------
当我们对同一个问题有两个模型时,由于每个模型可以给求解器不同的信息,通过把两个模型中的变量系到一起从而同时使用两个模型或许对我们是有帮助的。
.. literalinclude:: examples/allinterval3.mzn
:language: minizinc
:name: ex-allint3
:caption: CSPlib中全区间序列问题 ``prob007`` 的一个双重模型。 (:download:`allinterval3.mzn <examples/allinterval3.mzn>`).
:numref:`ex-allint3` 给出了一个结合 :download:`allinterval.mzn <examples/allinterval.mzn>`:download:`allinterval2.mzn <examples/allinterval2.mzn>` 特征的双重模型。
模型的开始来自于 :download:`allinterval.mzn <examples/allinterval.mzn>` 。我们接着介绍了来自于 :download:`allinterval2.mzn <examples/allinterval2.mzn>` 中的变量 :mzn:`y`:mzn:`v` 。我们使用全局约束 :mzn:`inverse` 来把变量绑到一起: :mzn:`inverse(x,y)` 约束 :mzn:`y`:mzn:`x` 的逆向函数(反之亦然),即, :mzn:`x[i] = j <-> y[j] = i`:numref:`ex-inverse` 中给出了它的一个定义。这个模型没有包含把变量 :mzn:`y`:mzn:`v` 关联起来的约束,它们是冗余的(实际上是传播冗余)。所以它们不会给基于传播的求解器多余的信息。 :mzn:`alldifferent` 也不见了。原因是它们被逆向约束变得冗余了(传播冗余)。
唯一的约束是关于变量 :mzn:`x`:mzn:`u` 和关系的约束以及 :mzn:`y`:mzn:`v` 的冗余约束。
.. literalinclude:: examples/inverse.mzn
:language: minizinc
:name: ex-inverse
:caption: 全局约束 ``inverse`` 的一个定义 (:download:`inverse.mzn <examples/inverse.mzn>`).
双重模型的一个优点是我们可以有更多的定义不同搜索策略的视角。运行双重模型,
.. code-block:: bash
$ minizinc --solver g12fd --all-solutions --statistics allinterval3.mzn -D "n=10;"
注意它使用逆向模型的搜索策略,标记变量 :mzn:`y` 在1714决策点和0.5秒内找到了所有的解。注意标记变量 :mzn:`x` 来运行同样的模型需要13142个决策点和1.5秒。
对称
--------
对称在约束满足和优化问题中是常见的。我们可以再次通过 :numref:`ex-queens` 来看一下这个问题。在 :numref:`fig-queens-sym` 棋盘的左上方展示了一个8皇后问题的解(标记为 "original")。剩下的棋盘展示了7个解的对称版本:旋转90度,180度和270度,还有垂直翻转。
.. _fig-queens-sym:
.. figure:: figures/queens_symm.*
8皇后问题解的对称变化
如果我们想要穷举8皇后问题的 *所有* 解,很明显我们需要通过穷举 *彼此之间不对称的* 解 为求解器省下一些工作,然后生成这些的对称版本。这是我们想要在约束模型中摆脱对称的一个理由。另外一个更重要的理由是,我们的求解器也可能会 **探索非解状态的对称版本!**
举个例子,一个典型的约束求解器可能会尝试把第1列皇后放在第1行上(这是可以的),然后尝试把第2列的皇后放到第3行上。 这在第一眼看是没有违反任何约束的。然而,这种设置不能被完成成为一个解(求解器会在一些搜索之后发现这一点). :numref:`fig-queens-sym-unsat` 在左上方的棋盘展示了这种设置。现在没有任何东西会阻止求解器去尝试,比如,在 :numref:`fig-queens-sym-unsat` 最低一行的左边第二种设置。其中第1列的皇后仍然在第1行,而第3列的皇后放在第2行。于是,即便是搜索一个解,求解器可能需要探索很多它已经看到并证明不可满足状态的对称状态!
.. _fig-queens-sym-unsat:
.. figure:: figures/queens_symm_unsat.*
8皇后问题不可满足约束的部分解的对称版本
静态的对称性破缺
~~~~~~~~~~~~~~~~~~~~~~~~
解决对称问题的建模技巧叫做 *对称性破缺* , 在它的最简单形式里, 需要在模型中加入约束使一个(不完整的)赋值的所有对称变换去除掉而保留一个。 这些约束称作 *静态的对称性破缺约束*
对称性破缺背后基本的想法是加入 *顺序* 。举个例子, 我们可以通过简单地加入约束使第一列的皇后必须在棋盘的上半部分,从而去除掉所有棋盘垂直翻转的。
.. code-block:: minizinc
constraint q[1] <= n div 2;
请相信以上约束会去除掉在 :numref:`fig-queens-sym` 中所有对称变换的一半。 为了去除 *所有* 对称,我们需要更多工作。
当我们把所有对称都表示成数组变量的排列,一组 *字典顺序约束* 可以用于破坏所有对称。 举个例子,如果数组变量名为 :mzn:`x` ,而翻转数组是这个问题的一种对称,那么以下约束可以破坏那种对称:
.. code-block:: minizinc
constraint lex_lesseq(x, reverse(x));
那么二维数组又怎么样呢?字典顺序同样适用,我们只需要把数组转换成一维的. 举个例子,下面的约束破坏了沿着其中一个对角线翻转数组的对称性(注意到第二个生成式里对换的数组下标):
.. code-block:: minizinc
array[1..n,1..n] of var int: x;

字典排序约束的好处在于我们可以加入多个(同时破坏几个对称性),而不需要它们互相干扰,只要我们保持第一个参数中的顺序一致即可。
对于n皇后问题,很不幸的是这个技巧不能马上适用, 因为又一些对称不能被描述成数组 :mzn:`q` 的排列。 克服这个问题的技巧是把n皇后问题表示成布尔变量。 对于每个棋盘的每个格子, 布尔变量表示是否有一个皇后在上面。现在所有的对称性都可以表示成这个数组的排列。 因为主要的n皇后问题的主要约束在整型数组 :mzn:`q` 里面更加容易表达, 我们只需要两个模型都用起来,然后在它们之间加入连通约束。 正如 :ref:`sec-multiple-modelling-and-channels` 中解释的一样。
加入布尔变量,连通约束和对称性破缺约束的完整模型展示在 :numref:`ex-queens-sym` 里面。 我们可以做一些小实验来检查它是否成功的破坏所有对称性。 尝试用不断增加的 :mzn:`n` 运行模型, 比如从1到10, 数一下解的个数(比如,使用 Gecode求解器的 ``-s`` 标志, 或者选择IDE中"Print all solutions"和"Statistics for solving")。 你应该可以获得以下数列的解: 1, 0, 0, 1, 2, 1, 6, 12, 46, 92。 你可以搜索 *On-Line Encyclopedia of Integer Sequences* (http://oeis.org) 来校验这个序列。

其他对称的例子
~~~~~~~~~~~~~~~~~~~~~~~~~~
许多其他问题都有内在的对称性,破坏这些对称性常常会令求解表现不一样。以下是一些常见的例子:
- 装箱问题: 当尝试把物品装入箱子时,任意两个有相同容量的箱子都是对称的
- 涂色问题: 当尝试为一个图涂色使得所有相邻的节点都有不同的颜色时,我们通常用整型变量对颜色建模。但是,对颜色的任意排列都是一种合法的涂色方案。
- 车辆路线问题: 如果任务是给顾客分配一些车辆,任何两辆有相同容量的车可能是对称的(这跟装箱问题是相似的)
- 排班/时间表问题: 两个有相同能力的职员可能是可以相互交换的,就像两个有相同容量或者设备的的房间一样
