In this paper we present efficient polynomial algorithms for finding a maximum bipartite subgraph for special classes of graphs. In general this problem is NP-complete, and it remains NP-complete even when the graph is restricted to be planar. However, putting further restrictions on the graph makes this
problem tractable. We have developed algorithms for finding a maximum bipartite subgraph for proper circular-arc, circular-arc, permutation, and split graphs. In numerous occasions, we used one technique, namely dynamic programming, for the development of the algorithms. Furthermore, the algorithms we designed, with slight modifications, can be adapted to solve the maximum bipartite subgraph problem which includes a nontrivial subset of vertices.
