Hi, I'm experiencing some problems in combining the functionalities of combinatorica and the built-in functions for graphs. In fact loading combinatorica shadows the built-in Graph function, and makes its use impossible. But while I need some of the functions in the combinatorica package (minimum/maximum spanning tree), i prefer the graphic and "lexical" representation of the built-in Graph. How do I "save" Graph when I load combinatorica, or how can I make it come back? Also (and this looks weird!), when i use ToCombinatoricaGraph (in GraphUtilites package) to convert a graph, the resulting object can be processed by MaximumSpanningTree, yielding a correct result, but not by MinimumSpanningTree which returns something like: MinimumSpanningTree[-Graph:<14,8,Directed>-] ...not even a combinatorica graph object. Thanks for your help!
