Tree Isomorphism: O(n) -- canonical form via AHU algorithm. Clearly in P. General Graph ISO: Status UNKNOWN -- believed not NP-Complete, not in P. It is GI-complete (its own complexity class). Best ...

Graphs are everywhere. In discrete mathematics, they are structures that show the connections between points, much like a public transportation network. Mathematicians have long sought to develop ...

(Phys.org)—László Babai with the Department of Computer Science and Mathematics at the University of Chicago has caused a lot of excitement in the computer science community by announcing recently ...

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 ...

Pilot contamination significantly degrades the minimum spectral efficiency (SE) in cell-free massive MIMO (CF-mMIMO) systems by inducing coherent interference. To mitigate this effect, effective pilot ...

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 ...

Abstract: In the design of analog integrated circuits, the placement stage in layout design plays a crucial role in determining the final circuit performance. Current automated placement algorithms ...

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 ...
