As for when an even faster algorithm will come along, no one knows. It could require a whole new breakthrough, or the secret ingredient may already be out there, waiting in a stack of old research ...

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 ...

According to Becker, the RAPIDS graph expansion can reduce by hours the amount of time to calculate big graph problems on social media data. “If I’m a data scientist, waiting two hours to calculate ...

Efficient Multicore Graph Algorithms. Julian Shun. Shun points out that it's hard to write efficient parallel code, and talks about criteria for optimizations: these depend, he says, on the type ...

Babai’s proposed algorithm doesn’t bring graph isomorphism all the way into P, but it comes close. It is quasi-polynomial, he asserts, which means that for a graph with n nodes, the algorithm’s ...

Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time. This means that the increasing complexity of the graphs increased the algorithm's running time ...

Refining with colors. Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.
