Multi-Valued Reasoning about Reactive Systems : Now Publishers : 9781638281382 : 01 Dec 2022 : Traditionally computer science has been Boolean in nature giving rise to systems based on proving correctness. Correctness is binary, but many questions we want to ask about systems are multi-valued. In modern computing systems this is becoming increasingly insufficient. In particular, beyond checking whether a system satisfies its specification, we may want to evaluate the quality in which the specification is satisfied. This has led to a shift from Boolean specification formalisms to multi-valued ones, which involves a development of multi-valued temporal logics as well as algorithms and tools for reasoning about such logics. This timely in-depth review describes the basics of specification and verification of reactive systems, and the automata-theoretic approach for them: by translating temporal-logic formulas to automata. As introductory material, the author describes the Boolean settin
