It is built on a event-based propagation mechanism with backtrackable structures.

CHOCO can be used for:

  • teaching (a user-oriented constraint solver with open-source code)
  • research (state-of-the-art algorithms and techniques, user-defined constraints, domains and variables)
  • real-life applications (many application now embed CHOCO)
