摘要
We prove that for any epsilon > 0 there exists an integer n(epsilon) such that the pathwidth of every cubic (or 3-regular) graph on n > n(epsilon) vertices is at most (1/6 + epsilon)n. Based on this bound we improve the worst case time analysis for a number of exact exponential algorithms on graphs of maximum vertex degree three. (c) 2005 Elsevier B.V. All rights reserved.
