YAGS 0.0.5 released!

We proudly announce the release of YAGS 0.0.5 - Yet Another Graph System. YAGS is a new free (GPLed) GAP package for Graph Theory. YAGS offers an ample set of functions; a graph-drawing subsystem; many methods for dealing with graph homomorphism; an Object-Oriented approach that simplifies the task of working with several different graph categories; and a generic backtracking subsystem useful to solve many combinatorial problems easily.
