[comp.sources.wanted] Graph manipulation software

erikb@eik.ii.uib.no (Erik Boman) (05/20/91)

Hello NetWorld !

I am looking for software that operate on graphs. 
(No, I do NOT mean x-y plots of functions or data ! )
I'm referring to graphs in the graph theoretical sence, 
i.e. structures with edges and vertices/nodes. 
Actually, I'm most interested in directed weighted graphs.

Is there a public domain package, preferably written in C, that
supports basic graph operations like topological sorting, finding
shortest path between two nodes, detecting cycles etc. ?

I am also looking for a program that can make neat pictures
of a graph with labels on edges and vertices. Even better if it
has a X-windows based user interface so I can interactively 
add and delete edges/nodes and move things around.

If anybody could give me a pointer to where I can find programs
supporting any of these features, I would be most grateful.

Thanks in advance,
