Abstract: In undirected graphs with real non-negative weights, we give a new randomized algorithm for the single-source shortest path (SSSP) problem with running time ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

Chinese computer scientists have solved a 40-year-old mathematics bottleneck, an advance that might help boost performance in hi-tech areas ranging from chip design and telecommunications to drone ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

The increasing impact of urban floods, driven by global climate change and the growing frequency of extreme weather events, poses significant threats to public safety, disrupts infrastructure, and ...

Graph theory is an integral component of algorithm design that underlies sparse matrices, relational databases, and networks. Improving the performance of graph algorithms has direct implications to ...

The original version of this story appeared in Quanta Magazine. If you’ve been making the same commute for a long time, you’ve probably settled on what seems like the best route. But “best” is a ...

Abstract: This research is conducted to design and develop a new algorithm for finding out the classic “Shortest Path” between every pair of vertices using an atypical approach. The approach follows ...
