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 ...

The legendary graph isomorphism problem may be harder than a 2015 result seemed to suggest. “In Laci Babai, you have one of the most legendary and fearsome theoretical computer scientists there ever ...

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 computer scientist has taken his colleagues on a rollercoaster ride. In the span of several days, László Babai of the University of Chicago walked back his earlier claim of making a major advance on ...

Theoretical computer scientists are normally a fairly sedate bunch, but are humming with excitement after a potential breakthrough in a long-standing problem called graph isomorphism. The result could ...

An innovative approach to solving a stubborn, but elementary, question in graph theory — the mathematical study of networks of nodes and their connections — may signal the first major theoretical ...
