This chapter presents the conclusions of this thesis.
We present a summary of the research and its contributions and discuss the future work arising from them.

\section*{Rewriting Architecture}
In \cref{ch:rewriting}, we presented the principle contribution of this thesis: \textbf{an architectural design for the rewriting of a \cml{}}.
We introduced a transformation language \microzinc{}, a minimal language used to describe how different expressions are rewritten into a \gls{slv-mod}.
At the core of this architecture lie formal rewriting rules for \microzinc{} against which an implementation can be checked.

In these \solvers{}, a functionally defined \variable{} can become unused when the \constraints{} that use \variable{} have already been \gls{satisfied}, independent of its \gls{fixed} value.
Like we can remove the defining \constraint{} during \gls{rewriting}, in a \gls{cp} \solver{} we could stop further \gls{propagation} of this \constraint{} and possibly speed up the solving.
\paragraph{Reasoning about Reification} Whether to a \constraint{} is \gls{reified} is a crucial decision that has to be made during \gls{rewriting}.
\section*{Reasoning about Reification}
Whether to a \constraint{} is \gls{reified} is a crucial decision that has to be made during \gls{rewriting}.
Making the wrong decision can significantly impact \gls{solver} performance.
In \cref{ch:half-reif}, we extend our architecture with our second contribution: \textbf{a formal analysis to reason about the \gls{reif} of \constraints{}}.
Not only does this analysis reduce the number of required \glspl{reif}, it is the first implementation that also automatically introduces \glspl{half-reif} when possible.

However, \glspl{propagator} for this form are still easy to design/implement, and they ensure that the \gls{cvar} is fixed through \gls{propagation}.
Finally, automated \gls{half-reif} in \minizinc{} will allow new solving performance improvements by allowing \solver{} implementers to experiment with \glspl{decomp} or \glspl{propagator} for \gls{half-reified} \constraints{}.
\paragraph{Incremental Solving} Using a \cml{} as the interface for a \gls{meta-optimization} toolchain can be very intuitive and opens up new opportunities.
\section*{Incremental Solving}
Using a \cml{} as the interface for a \gls{meta-optimization} toolchain can be very intuitive and opens up new opportunities.
The modeller can describe the process as a changing \cmodel{}.
The overhead of the repeated \gls{rewriting} process to arrive at a \gls{slv-mod} can, however, be a hindrance.
\Cref{ch:incremental} presents our final contribution: \textbf{two methods to practically eliminate the overhead of using \cmls{} in \gls{meta-optimization}}.

The utilization of the presented methods might offer a significant improvement in performance, allowing the solving of more complex problems.
Finally, new \gls{meta-optimization} techniques could require extensions of the methods presented.

\section*{Summary}
In conclusion, this thesis presented an architecture for the \gls{rewriting} of \cmls{}.
This architecture has been designed with modern usages of these languages in mind, such as \gls{rewriting} for low-level \solvers{} and \gls{meta-optimization}.
It is efficient and incremental, but easily extensible with many simplification techniques.
It also includes a formal framework to reason about \gls{reif} that is able to introduce \glspl{half-reif}.
