Enumerate all subgraphs

Hi,

I am trying to exact all the subgraphs containing node A. Anyone could enlighten me on this?

Thanks in advance.

It is not very clear to me what you mean by “all subgraphs”.

Do you really mean all subgraphs? I suspect you mean something much more specific such as induced subgraphs or even connected subgraphs.

All subgraphs is a trivial, but combinatorially explosive, problem.
