Cpbased

Cpbased is a term used in technology and research to denote approaches, tools, or systems that are based on constraint programming (CP). In this usage, cp-based methods model problems as constraint satisfaction problems (CSPs) or constraint optimization problems (COPs) defined by variables, domains, and relationships that constraints impose. A CP solver then explores possible assignments, using propagation, domain filtering, and search strategies to find feasible solutions or optimize objectives.

Cpbased approaches are commonly applied to scheduling, timetabling, rostering, resource allocation, configuration, and puzzle solving. They are often contrasted with methods based on linear programming, SAT solving, or general-purpose heuristic search. CP-based systems can be extended with global constraints to capture common patterns, and they may integrate with other paradigms to handle numerical optimization or uncertainty.

Tools and languages frequently described as cp-based include MiniZinc as a modeling language, and solver libraries such as OR-Tools CP-SAT, Choco, Gecode, and JaCoP. In documentation and discourse, cp-based is sometimes hyphenated as "cp-based" and occasionally written as "cpbased" in branding or code identifiers, though consistency varies.

Note: Cpbased is not a single, standardized product or organization; it is a descriptive label used across multiple projects that employ constraint programming techniques.
