JaCoP

JaCoP (Java Constraint Programming) is an open-source software library that helps programmers solve complex problems involving multiple constraints, such as scheduling, resource allocation, or puzzle-solving. It uses advanced algorithms to find solutions that satisfy all the given conditions efficiently. By defining variables and constraints, users can model real-world problems declaratively, and JaCoP automatically explores possible solutions to identify feasible ones or optimize outcomes. It is widely used in research and industry for tackling problems that require finding the best or a suitable arrangement under various restrictions.
