Abstract

We present refusal simulation relation as a candidate for the finest branching time relation that is solely based on all locally observable and testable properties of processes, and no other properties. Apart from several known characterisations, we introduce a new one in terms of interactive games. Two general formats of transition rules, based on the new Ordered Structural Operational Semantics approach [20], are given such that refusal simulation and its rooted version are preserved in arbitrary process languages definable within the respective formats.
