Hi all,

I'm trying to implement the Boruvka's algorithm and I need to know is a
grah is connected or not.
So I'd like to propose a simple algorithm to do that.
A simple way to implement that is run a depth-first or breadth-first search
starting from an arbitrary vertex. If the number of the vertices touched
are the same of the origina graph, the graph is connected.

cool, go for it :-)


Moreover the algorithm could count the number of che "connected componet" (
http://en.wikipedia.org/wiki/Connected_component_(graph_theory).

well you get that number if you actually map each vertex to a connected component, which means you could need to run the search algorithm more than once.

As a unified solution maybe we could go for an algorithm that returns the connected components as a collection of graphs, and then in your case you just check that there is only one connected component.

what do you think about that?
