Benchmark Problems

The list of benchmark problems usually used in the CP Solvers programming competetion. Check also the related XCSP tools.
The organizers of the International Workshop on Constraint Propagation and Implementation organize a Solver Competition and make available the benchmark problems used during the competition. Such as the ones used in the 2005 competition. Such problem instances are typically written using the new standards for representing CSP instances: an XML representation and also a table representation.
CLib: Configuration Benchmarks Library.
