EasyCSP is an open-source Java library for Constraint Satisfaction Programming.

EasyCSP is an open-source Java library for Constraint Satisfaction Programming.

EasyCSP offers search algorithms for both CSPs and CSOPs.

EasyCSP supports CSPs to be defined using objects or int expressions.

Dependencies

Requires Java 8 or later.
