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 ...

Algebraic structures form the backbone of modern abstract algebra, encapsulating a wide range of systems such as groups, rings, fields, and modules, each characterised by distinct axiomatic properties ...

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 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 ...

The fraternity of problems that confound computers has lost a prominent member. Computer scientist László Babai presented a new algorithm this year that efficiently tackles the graph isomorphism ...
