An Effective Refinement Algorithm Based on Swarm Intelligence for Graph Bipartitioning

Partitioning is a fundamental problem in diverse fields of study such as VLSI design, parallel processing, data mining and task scheduling. The min-cut bipartitioning problem is a fundamental graph partitioning problem and is NP-Complete. In this paper, we present an effective multi-level refinement algorithm based on swarm intelligence for bisecting graph. The success of our algorithm relies on exploiting both the swarm intelligence theory with a boundary refinement policy. Our experimental evaluations on 18 different benchmark graphs show that our algorithm produces high quality solutions compared with those produced by MeTiS that is a state-of-the-art partitioner in the literature.
