## Abstract

Goal relationships resulting from the initial data and subsequent processing can be used to dvnamicallv construct a partial topology of the ~olution space based on what appear to be feasible solutions. This structure can be used to make control decisions that significantly reduce the amount of search required to solve a problem in a complex domain. We examine the utility of this approach in the context of a multi-le~el, cooperative knowledge source model of problem solving. We present a taxonomy of goal relationships for constructing partial topologies of the solution space and show that mechanisms using this information can be built as natural extensions of an integrated data-directed and goal-directed arc hitecture. Examples and performance results demonstrating how these additions improve the system's ability to evaluate potential activities are provided.
