here's a textbook with an algorithm for generating all the cycles of a digraph. Reingold, Nievergelt, Deo, "Combinatorial Algorithms" Prentice-Hall, 1977 pp348-353. One nice thing about this book is that its references are fully annotated. In this case, the reference points to: Read, R. C., and R. E. Tarjan, "Bounds on Backtrack Algorithms for Listing Cycles, Paths, and Spanning Trees," Networks 5(1975), 237-252. Don W. Gillies, Dept. of Computer Science, University of Illinois 1304 W.
