The Timed Concurrent Constraint Language (tccp in short) is a concurrent logic language based on the simple but powerful concurrent constraint paradigm of Saraswat. In this paradigm, the notion of store-asvalue is replaced by the notion of store-as-constraint, which introduces some differences w.r.t. other approaches to concurrency.
