The tccp Interpreter.

Abstract: The Timed Concurrent Constraint language (tccp in short) is a declarative language inspired by some formalisms specially developed to deal with concurrent and reactive systems. It is defined as a timed extension of the Saraswat''s Concurrent Constraint Paradigm (ccp in short) which makes the new language suitable for modeling reactive systems. The computational model of ccp is based on agents generating (telling) and checking (asking) partial information (constraints) on a global store (a conjunction of constraints). tccp inherits the main characteristics of ccp: it is parametric w.r.t. a constraint system and non-deterministic. This work presents the tccpInterpreter system, which is the result of implementing the tccp language in Maude. Maude has been shown to be well suited for the task of prototyping the semantics of programming languages. Our tccpInterpreter parses a given program and simulates its behavior, also allowing us to reuse the Maude features to execute and analyze tccp programs. [Copyright &y& Elsevier]
