The latest ITU-T standard syntax of Message Sequence Charts (MSCs) 16] o ers several operators to compose MSCs in a hierarchical, iterating, and nondeterministic way. However, curr...
The Constraint Simplification Rules (CSR) subset of CHR and the flat subset of LCC, where agent nesting is restricted, are very close syntactically and semantically. The first con...
