Abstract : The document reports work on two heuristic problem solving systems, Ref2 and POPS. Both systems accept problems stated as programs in a nondeterministic programming language, and solve the problems by applying heuristic methods to find successful executions of the programs. Ref2 is patterned after Richard Fike's system, REF-ARF, and contains the problem solving methods of REF-ARF, as well as additional methods based on an alternative representation for the problem context. Ref2 is also able to solve a class of integer programming problems. POPS is a revised and extended version of Ref2, obtained by the addition of goal directed methods based on concepts from GPS.
