Title
On a reduction of the weighted induced bipartite subgraph problem to the weighted independent set problem.
Abstract
We study the weighted induced bipartite subgraph problem (WIBSP). The goal of WIBSP is, given a graph and nonnegative weights for the nodes, to find a set W of nodes with the maximum total weight such that a subgraph induced by W is bipartite. WIBSP is also referred as to the graph bipartization problem or the odd cycle transversal problem. In this paper, we show that WIBSP can be reduced to the weighted independent set problem (WISP) where the number of nodes becomes twice and the maximum degree increase by 1. WISP is a well-studied combinatorial optimization problem. Thus, by using the reduction and results about WISP, we can obtain nontrivial approximation and exact algorithms for WIBSP.
