Hello!
We have a graph that is not directional. We want an algorithm to find
out if this graph is divided to two parts or not.

If I remember correctly, checking whether a graph is strongly connected is a NL-hard problem. So there shoul be no big trouble in doing it.

I guess something like looking at the multiplicative closure of the adjacency matrix will do the trick.
