A Game Characterization for Contrasimilarity
arXiv:2108.10492 · doi:10.4204/EPTCS.339.5
Abstract
We present the first game characterization of contrasimilarity, the weakest form of bisimilarity. The game is finite for finite-state processes and can thus be used for contrasimulation equivalence checking, of which no tool has been capable to date. A machine-checked Isabelle/HOL formalization backs our work and enables further use of contrasimilarity in verification contexts.
