The Max-Bisection and Min-Bisection problems are to find a partition of the vertices of a graph into two equal size subsets that respectively maximizes or minimizes the number of edges with endpoints in both subsets. We design the first polynomial time approximation scheme for the Max- Bisection problem on arbitrary planar graphs solving a long time standing open problem. The method of solution involves...
