Fast and scalable constraint solver
MINION is a general-purpose constraint solver, with an expressive input language based on the common constraint modelling device of matrix models. Focussing on matrix models supports a lean, highly-optimised implementation.
This contrasts with current constraint toolkits, which, in order to provide ever more modelling and solving options, have become progressively more complex at the cost of both performance and usability.
MINION is a black box from the user point of view, that deliberately comes with very few options. This, combined with its raw speed, makes MINION a substantial step towards Puget's `Model and Run' constraint solving paradigm.
NOTE: MINION is still in the beta stage of development. Bugs can be expected.
