Hi Jon, This may not be of much help if you have only access to Mathematica 7 but Mathematica 8.0.1 gives: << Combinatorica` General::compat: Combinatorica Graph and Permutations functionality has been superseded by preloaded functionaliy. The package now being loaded may conflict with this. Please see the Compatibility Guide for details. In[3]:= NetworkFlow[ FromAdjacencyMatrix[{{Infinity, 5, 3, Infinity, Infinity, Infinity}, {0, Infinity, 2, 3, Infinity, Infinity}, {0, 2, Infinity, Infinity, 4, Infinity}, {Infinity, 0, Infinity, Infinity, 1, 2}, {Infinity, Infinity, 0, 0, Infinity, 5}, {Infinity, Infinity, Infinity, 0, 0, Infinity}}, EdgeWeight], 1, 6] Out[3]= 7 It does not hang but the documentation is very sparse so without spending a chunk of time I am not sure if the output is what you expected.
