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 ...

This study views rumor propagation as an undirected graph. We simulate rumor propagation using GCN and classify rumors using a fully connected layer. • GAT (Veličković et al., 2018): Graph attention ...

Information dissemination on social media is often accompanied by a large number of false or true rumors. The spread of these rumors on social network platforms does serious harm to social stability.

Specifically, we use Graph Convolutional Networks (GCN) to represent the rumor propagation tree with source and response posts as graphs, and update node representations based on responses to rumors ...

The new algorithm checks planarity in a number of steps proportional to the cube of the logarithm of the number of nodes in the graph — an exponential improvement. Holm and Rotenberg, a computer ...

Now a trio of computer scientists has solved this long-standing problem. Their new algorithm, which finds the shortest paths through a graph from a given “source” node to every other node, nearly ...

The team proposed Graph-Decomposed k-NN Searching Algorithm to improve the time-efficiency of nearest nodes searching. In the research, A graph-decomposed tree is constructed from road network.

Furthermore, MOSAIC can complete one iteration of the Pagerank algorithm on a trillion-edge graph in 21 minutes, outperforming a distributed disk-based engine by 9.2X.” The tile structure is also ...
