The graph colouring problem, a classic NP-hard challenge, is central to many practical applications such as scheduling, resource allocation and network management. Recent advances have seen the ...

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 ...

But researchers commonly analyze graphs with billions or more connections. And so they’ve developed algorithms that assign colors for them. These algorithms, however, are slow and had been “stuck more ...
