Abstract: A system and method of distributed computation based upon a novel partitioning of computer networks. In the distributed computing system of the present invention, instructions are disseminated to select agents on a computer network, each of which is a member of at least one “path,” a path being an ordered set of one or more connected agents within the network.

The basic components of the computing system are agents, probes and paths. The agents are interconnected forming a network and a path is an ordered sequence of agents.
