How do I find all cut vertices (aka articulation points) in a graph?
One (not particularly efficient) way that occurs to me is to first find the biconnected components of a graph g, for which there is a built-in function (KVertexConnectedComponents). Then, use the fact …

How do I find all cut vertices (aka articulation points) in a graph?
Given a connected graph $G = (V,E)$, we say that a vertex $v \in V$ is a cut vertex of $G$ if the removal of $v$ from $G$ causes $G$ to become disconnected.
How can I find all cut vertices of a given …

Deleting zero edges from a graph causes bizarre behavior
Bug introduced in 10.3.0 and fixed in 10.4.
Consider the following (very simple) graph, with two vertices and one edge:
g = Graph[{1, 2}, {1 <-> 2}];
I can use EdgeDelete to remove the edge from …
