Precisely when the success of artificial intelligence (AI) sub-symbolic techniques makes
them be identified with the whole AI by many non-computer-scientists and non-technical …

Rewriting logic is a simple computational logic that can naturally express both concurrent
computation and logical deduction with great generality. This paper provides a gentle …

Formal methods for the specification and verification of hardware and software systems are
becoming more and more important as systems increase in size and complexity. The aim of …

Maude is a high-level language and a high-performance system supporting executable
specification and declarative programming in rewriting logic. Since rewriting logic contains …

The world is increasingly populated with interactive agents distributed in space, real or
abstract. These agents can be artificial, as in computing systems that manage and monitor …

This paper proposes membership equational logic—a Horn logic in which the basic
predicates are equations t= t′ and membership assertions t: s stating that a term t belongs …

The problem of testing a linear temporal logic (LTL) formula on a finite execution trace of
events, generated by an executing program, occurs naturally in runtime analysis of software …

A goal of runtime software-fault monitoring is to observe software behavior to determine
whether it complies with its intended behavior. Monitoring allows one to analyze and recover …

This is an introduction to the philosophy and use of OBJ, emphasizing its oper-ational
semantics, with aspects of its history and its logical semantics. Release 2 of OBJ3 is …

CafeOBJ is an industrial strength modern algebraic specification language, a successor of
the famous OBJ language, and directly incorporating new paradigms such as behavioural …
