In practice, existing algorithms can do the job in reasonable time, but it was possible that extremely complex graphs would make the problem intractable. Not anymore. “My first thought was that ...

“It’s an extremely clever composition of these ideas,” Khanna said. The algorithm is the first for negative-weight graphs that runs in “near-linear” time — which means its runtime is nearly ...

When’s the last time Google replaced its algorithm ... “Conversational Search” Goes Live On Chrome), but it had only been doing it really within its Knowledge Graph answers.

The 1996 algorithm required a number of computational steps that was roughly proportional to the square root of the number of nodes in the graph. “[It’s] much better than just doing it from scratch ...
