Abstract: The max-bisection problem is one of classical NP-hard problems, and has lots of applications. This paper presents a discrete filled function method for solving the max-bisection problem. It adopts a quickly iterative improvement algorithm as local search method. A filled function and an auxiliary problem of the max-bisection problem are constructed, and some properties of the auxiliary problem are studied. Maximization of the auxiliary problem uses the local search method to find better solutions. The experiments are done on a number of large scale benchmarks with 800 to 10, 000 vertices from the literature. The experimental results show that the proposed algorithm is efficient.
