For the reverse question — whether graph isomorphism is in P — the evidence is more mixed. On the one hand, there are practical algorithms for graph isomorphism that can’t solve the problem ...

For decades computer scientists had been trying to develop a fast algorithm for determining when it’s possible to add edges to a graph so that it remains “planar,” meaning none of its edges cross each ...

Mathematicians have long sought to develop algorithms that can compare any two graphs. In practice, many algorithms always ...

“When corporations or governments are not legally or otherwise incentivized to disclose information about their algorithms, we might consider a different, more adversarial approach,” Diakopoulos ...

Graph mining algorithms typically focus on finding dense connections between individual pairs of points, such as two people who frequently communicate on social media. However, the researchers ...

It’s often assumed that Dijkstra’s algorithm, or the A* graph traversal algorithm is used, but the reality is that although these pure graph theory algorithms are decidedly influential ...

To this end, [Ken Shirriff] set about reverse engineering the 8086’s multiplication algorithm. [Ken]’s efforts were achieved by using die photos of the 8086 chip. Taken under a microscope ...
