Abstract

We study exact algorithms for the MAX-CUT problem. Introducing a new technique, we present an algorithmic scheme that computes a maximum cut in graphs with bounded maximum degree. Our algorithm runs in time O^*(2^(^1^-^(^2^/^@D^)^)^n). We also describe a MAX-CUT algorithm for general graphs. Its time complexity is O^*(2^m^n^/^(^m^+^n^)). Both algorithms use polynomial space.
