Abstract

This work is concerned with the termination problem of interpreted graphs. An interpreted graph can be considered as an abstract model of algorithms; it consists of a directed graph, where: 1. With each vertex v, there is associated a domain Dv, and 2. With each arc a leading from vertex v to vertex v', there is associated a total test predicate Pa(Dv → {T, F}) and a total function fa (Dv* → Dv'), where Dv* = {x | x ∈ Dv ∧ Pa (x) = T}.
