Graph isomorphism problem might not be hard. But it's very hard to prove this problem is not hard.
If I understand the question properly, you can have ONE single algorithm, which will work by accepting one of several reference graphs as its input (in addition to the input of the unknown graph which isomorphism with the reference graph is to be asserted).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
