Stirling numbers of the second kind are always nonnegative and yet: ``` julia> stirlings2(26,10) -5247188700862703611 ``` The same issue plagues `stirlings1`. We have ``` julia> stirlings1(26,10) 9107464261356742080 ``` but the...

Isomorphism

A natural addition is a function to find isomorphisms between graphs. I've written some code that does that. (I'm sure it works for simple graphs and simple digraphs. Not sure...

Thanks for this package. I stumbled across a corner case that should be easy to handle. If all entries in the matrix are `missing`, then `hungarian` throws an error: ```...

When a `Multigraph` has multiple edges, the incidence matrix should have repeated, identical columns. That is, there should be as many columns as there are edges. ``` julia> using Graphs,...

When adding a single loop to a `Multigraph`, its multiplicity ought to be one, not two: ``` julia> using Graphs, Multigraphs julia> g = Multigraph(4) {4, 0} undirected Int64 multigraph...
