摘要

A (P) over right arrow (3)-decomposition of a directed graph D is a partition of the arcs of D into directed paths of length 2. We characterize symmetric digraphs that do not admit a (P) over right arrow (3)-decomposition. We show that the only 2-regular, connected directed graphs that do not admit a (P) over right arrow (3)-decomposition are obtained from undirected odd cycles by replacing each edge by two oppositely directed arcs. In both cases, we give a linear-time algorithm to find a (P) over right arrow (3)-decomposition, if it exists. (C) 2016 Elsevier B.V. All rights reserved.
