Constraint propagation works by reducing domains of variables, strengthening constraints, or creating new ones. This leads to a reduction of the search space, making the problem easier to solve by some algorithms.

What is a CP solver?
Constraint programming (CP) is a paradigm for solving combinatorial problems that draws on a wide range of techniques from artificial intelligence, computer science, and operations research. In constraint programming, users declaratively state the constraints on the feasible solutions for a set of decision variables.
What is Choco programming?
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 is an open- source software, distributed under a BSD licence and hosted by source- forge.May 12, 2010
What is Choco Java?
Choco is a Free Open-Source Java library dedicated to Constraint Programming. The user models its problem in a declarative way by stating the set of constraints. that need to be satisfied in every solution. Then, the problem is solved by alternating constraint filtering algorithms with a search mechanism.
