Abstract: Constraint programming(CP) as a practical AI programming paradigm has gained ever-increasing significance in recent years. A challenging issue for CP is how to achieve the conjunctive merits of declarative representation, systematic and heuristic search , and computational efficiency. This paper describes the work on a constraint language COPS. The project is motivated to explore the practical techniques in constraint languages that enable them to solve complet real-world problems that are difficult with conventional programming languages. The kernel syntax of COPS is presented, the semantics are briefly introduced, and the main inference techniques are described.
