Abstract : tau-confluence is a reduction technique used in explicit state model-checking of labeled transition systems to avoid the state explosion problem. In this report, we propose a new on-the-fly algorithm to calculate partial tau-confluence, and propose new techniques to do so on large systems in a compositional manner. Using information inherent in the way a large system is composed of smaller systems, we show how we can deduce partial tau-confluence in a computationally cheap manner. Finally, these techniques are applied to a number of case studies, including the rel/REL atomic multicast protocol.
