Abstract

A branch- and-bound type algorithm is developed to optimize the evaluation of a set of expressions. The algorithm proceeds in a depth-first manner and achieves an optimal solution. The algorithm is applied to optimize the evaluation of sets of relational expressions. Analogies to the heuristic information associated with theA* algorithm are investigated. Examples are presented illustrating the use of the algorithm. Pragmatics associated with the algorithm and its application to Boolean optimization are also discussed.
