WebMULTILEVEL GRAPH PARTITIONING 361 for all three phases: coarsening, partition of the coarsest graph, and re nement. In particular, we present a new coarsening heuristic (called heavy-edge heuristic) for which the size of the partition of the coarse graph is within a small factor of the size of the nal partition obtained after multilevel re nement. http://duoduokou.com/algorithm/40777768380173799159.html
