Designing custom algorithms

Constraint Programming

Constraint Programming (CP) is a wonderful technology enabling to solve constrained configuration and optimization problems. At the crossroad between Artificial Intelligence and Operations Research, this component-based approach allows to build applications that are flexible, efficient and scalable. We design efficient models as well as advanced components (global constraints, search heuristics, large neighborhood search, etc.). We use different solvers, notably Choco Solver that we develop together with IMT Atlantique.

Linear Programming

Linear Programming (LP) is a technology stemming from Operations Research that is used to solve combinatorial problems. We develop linear, integer and mixed models and embeds advanced solving techniques, such as Branch and Cut or CP hybrids. We use both commercial and open source solvers.

Dedicated algorithms

We design specific algorithms to best meet your needs : greedy algorithms, meta-heuristics, etc. Our constraint programming background enables us to design efficient algorithms that are easy to maintain, even if no solver is used.
