CAP - Concurrent Action and Planning: Using PVM-Prolog to Implement Vivid Agents
Jan 1997
First we describe PVM-Prolog, a Prolog core extended by an interface to PVM the Parallel Virtual Machine, a standard software which allows to view a network of heterogenous machines as a single parallel computer. PVM-Prolog includes a process-internal thread concept to realize fine-grain concurrency. Second, we review the concept of vivid agents [Wag96] and develop the architecure CAP (Concurrent Action and Planning) that serves as an operational semantics for vivid agents. Finally, we merge the above two lines of research by showing that PVM-Prolog is an excellent candidate to implement vivid agents and multi-agent systems, in general: the coarse-grain parallelism is used
to spawn agents in a network, while the fine-grain concurrency is used to run a perception-reaction-cycle and a planning facility for each agent concurrently.
