The two important methods of finding undirected longest cycles, namely, the extension + rotation and the branch trimming, both have their own disadvantages. Any undirected basic cycle can always be decomposed into several atomic cycles which are connected with one another by a common edge in a certain order. Along this line, this paper proposes a new efficient algorithm for longest cycles based on the permutation of a finite candidate set of atomic cycles, which is able to reduce the time cost and guarantee the termination. Experimental results on some real cases demonstrate the effectiveness of the proposed algorithm.
