Methods of proving that a term-rewriting system terminates are presented. They are based on the notion of "simplification orderings", orderings in which any term that is homeomorphically embeddable in another is smaller than the other. A particularly useful class of simplification orderings, the "recursive path orderings", is defined. Several examples of(More)
A common tool for proving the termination of programs is the <italic>well-founded set</italic>, a set ordered in such a way as to admit no infinite descending sequences. The basic approach is to find a <italic>termination function</italic> that maps the values of the program variables into some well-founded set, such that the value of the termination(More)
This survey describes methods for proving that systems of rewrite rules are terminating programs. We illustrate the use in termination proofs of various kinds of orderings on terms, including polynomial interpretations and path orderings. The effect of restrictions, such as linearity, on the form of rules is also considered. In general, however, termination(More)
