Abstract
A system is disclosed for computing an initial partition of a graph comprising nodes and the edges that connect the nodes. In one embodiment this initial partition is presented for subsequent use by the Kernighan-Lin system of graph partitioning. The Subject System uses a combination of a seed-growth heuristic and a stochastic-search process to compute an initial partition. The seed-growth heuristic builds a partition by iteratively augmenting an initial set of seed nodes. The search process searches for good sets of seed nodes to use. The resulting combination of seed-growth heuristic, stochastic-search process, and the Kernighan-Lin algorithm constitutes a superior system for partitioning graphs. The Subject System can be applied to graph-partitioning problems that arise in circuit design, computer architecture, routing in computer networks, database design, distributed and parallel processing, and many other domains.
