CHOCO is a java library for constraint satisfaction problems (CSP) and constraint programming (CP).
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)

CHOCO is involved in the Java Specification Requests 331 : Constraint Programming API, winner of JCP Award for The Most Innovative JSR of 2010.
JSR-331 is an official standard now! See Constraint Programming Standardization Blog.
