摘要：
In this paper, we introduce the notion of a pyramidal tour with step-backs which is an extension of a pyramidal tour. By using this idea we shall show that for a class of distance matrices an optimal tour of traveling salesman problem can be computed in polynomial time. (C) 1998 Elsevier Science B.V.
