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

A new algorithm efficiently solves the graph isomorphism problem, computer scientist László Babai announced November 10 at a Combinatorics and Theoretical Computer Science seminar at the ...

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 ...

Computer scientists are abuzz over a fast new algorithm for solving one of the central problems in the field. (January 15, 2017, update: On January 4, Babai retracted his claim that the new algorithm ...

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 lighten the computational burden, the PNNL team turned to a type of algorithm known as graph coloring—a specialty of Ferdous and Halappanavar. That approach allows researchers to explore ...

Like the core algorithm, Google’s Knowledge Graph periodically updates. But little has been known about how, when, and what it means — until now. I believe these updates consist of three ...

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 ...

A tree-based decomposition solution to the k-NN search problem is designed into the TEN-Query algorithm. A tree-based decomposition index is proposed to convert the graph into a tree structure ...
