Hi everyone! 

I hope you are doing well, I wanted to ask you if you can recommend me some papers about Graph Theory, they are for my algorithm class, we are going to analyze some of them, and I'm looking for some nice papers about graph algorithms, I'm really interested in find some about **Flow Theory**, I hope you can help me recommend me some good ones... not only about flows, but another topic would be great too. 

Thank you everyone!
