Abstract

Labelled state transition system (LSTS) is a formalism intended to combine the benefits of both state-based and action-based models. However, its existent equivalence preserves many properties with the cost of poor reduction effects. A new equivalence is presented, namely called reverse observation equivalence which is defined in the opposite direction to observation equivalence and orients the invariant checking of LSTS. Experiments show that the new semantics is efficient in the context of compositional reachability analysis.
