Abstract

This work presents game-based model checking for abstract models with respect to specifications in μ-calculus, interpreted over a 3-valued semantics. If the model checking result is indefinite (don't know), the abstract model is refined, based on an analysis of the cause for this result. For finite concrete models our abstraction-refinement is fully automatic and guaranteed to terminate with a definite result true or false.
