Abstract

The fastest known algorithm for checking bisimulation equivalence of normed context-free processes worked in O(n 13) time. We give an alternative algorithm working in \(O(n^8 {\sl polylog} n)\) time, As a side effect we improve the best known upper bound for testing equivalence of simple context-free grammars from \(O(n^7 {\sl polylog} n)\) to \(O(n^6 {\sl polylog} n)\).
