Abstract:

This paper puts forward a blocked calculation algorithm for the nesting μ-calculus formula by using the monotonicity of the iterate calculation of the μ-calculus formula, whose time complexity is and space complexity is . For the lower space complexity of the algorithm, it is possible to solve the μ-calculus formula whose fixed-point operator is deep nesting, which is significant in the model checking.

Key words: model checking, μ-calculus, calculation complexity, NP co-NP problem
