Automata-Based Termination Proofs

Original language description

This paper proposes a framework for detecting termination of programs<br>handling infinite and complex data domains, such as pointer structures. In<br>this framework, the user has to specify a finite number of well-founded relations<br>on the data domainmanipulated by these programs. Our tool then builds an initial<br>abstraction of the program, which is checked for existence of potential infinite<br>runs, by testing emptiness of its intersection with a predefined Buchi automaton.<br>If the intersection is non-empty, a lasso-shaped counterexample is found. This<br>counterexample is checked for spuriousness by a domain-specific procedure, and<br>in case it is found to be spurious, the abstraction is refined, again by intersection<br>with the complementof the Buchi automaton representing the lasso. We have instantiated<br>the framework for programs handling tree-like data structures, which<br>allowed us to prove termination of programs such as the depth-first tree traversal,<br>the Deu
