generic development environment Gecode Gecode is an open source C++ toolkit for developing constraint-based systems and applications. Gecode provides a constraint solver with state-of-the-art performance while being modular and extensible. Gecode is: open Gecode is radically open for programming: it can be easily interfaced to other systems. It supports the programming of new constraints, branching strategies, and search engines. New variable domains can be programmed at the same level of effici...
