WeaklyConnectedGraphQ

WeaklyConnectedGraphQ[g] yields True if the graph g is weakly connected, and False otherwise.

Examples

Test if a graph is weakly connected:

g = Graph[{1 -> 2, 2 -> 3}];
WeaklyConnectedGraphQ[g]
(* True *)

Disconnected graph:

WeaklyConnectedGraphQ[Graph[{1 -> 2, 3 -> 4}]]
(* False *)
