(Phys.org)—László Babai with the Department of Computer Science and Mathematics at the University of Chicago has caused a lot of excitement in the computer science community by announcing recently ...

Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop ...

Complexity fans and algorithm researchers are excitedly whispering this week about what might be the “the theoretical computer science result of the decade,” in the words of MIT professor Scott ...

For decades, the graph isomorphism problem has held a special status within complexity theory. While thousands of other computational problems have meekly succumbed to categorization as either hard or ...

A puzzle that has long flummoxed computers and the scientists who program them has suddenly become far more manageable. A new algorithm efficiently solves the graph isomorphism problem, computer ...

Just five days after posting a retraction, László Babai announced that he had fixed the error in his landmark graph isomorphism algorithm. The back and forth ...

Recognise two graphs as being isomorphic if there is a one-to-one relationship between the vertices of the two graphs based on, for instance, vertex degrees and adjacency matrices State the ...

The legendary graph isomorphism problem may be harder than a 2015 result seemed to suggest. Click to tell Google to prioritize Quanta and see more of the best coverage of science and math in your ...
