Abstract

A blackboard system in which the experts operate concurrently is described and implemented. The parallel program, which carries out a Penrose tiling of a planar area, provides insight into, and requires resolution of, many of the problems which must be addressed in implementing a more general concurrent blackboard system. A more versatile distributed knowledge system is also proposed. This model is based on a tree of concurrent blackboard systems in which partial solutions to various subproblems are developed at interior nodes and are piped to the root where the overall problem solution is arrived at.
