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 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 ...

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 ...

A lot happened in mathematics this year. High school exam problems went viral. Terry Tao solved the Erdös Discrepancy Problem and while most mathematicians would have submitted the paper to a top math ...

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 ...

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 ...
