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:
...not even a combinatorica graph object.
Thanks for your help!
