WebGraph partitioning problem, which is one of the most important topics in graph theory, usually asks for a partition of the vertex set of a graph into pairwise disjoint subsets with various requirements. It comes from the well-known Max-Cut Problem: Given a graph G, find the maximum bipartite subgraph of G. WebGraph partitioning is the problem of dividing the nodes of a graph into balanced par-titions while minimizing the edge cut across the partitions. Due to its combinatorial nature, many approximate solutions have been developed.
