CP-style scheduling model with the numberof operator, solved by a MIP solver¶

Description: Scheduling model with the Constraint Programming numberof operator, solved with a MIP solver. New MIP solver drivers based on the [MP library](https://amplmp.readthedocs.io/) enable CP-style modeling.

Simple sudoku solver using logical constraints (with GUI)¶

Description: Simple sudoku model with two formulations: as a Constraint Programming problem using the alldiff operator and as a MIP. Note that the CP formulation is more natural but it needs a solver supporting logical constraints or a MIP solver with automatic reformulation support (see [here](https://amplmp.readthedocs.io/) for more information).
