A header-only C++ implementation of the single-source shortest path (SSSP) algorithm for sparse directed graphs with non-negative weights, based on the 2025 paper by Duan et al. This algorithm is ...

Dijkstra is a legend in computer science and his algorithm, which he published in 1959, predates packet switching by a few years. The specification for OSPF (Open Shortest Path First (OSPF), one of ...

Why is a straight line always the shortest path between two points? 📐 This video explains the result using a variational approach, showing how minimizing distance leads naturally to a straight line ...

Abstract: Fault-tolerant reconfiguration is essential for improving the reliability and efficiency of multiprocessor arrays. However, existing reconfiguration approaches primarily focus on algorithmic ...

Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

SAN FRANCISCO, Nov 12 (Reuters) - IBM (IBM.N), opens new tab announced on Wednesday it has built a new experimental quantum computing chip called Loon that demonstrates it hit a key milestone toward ...

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 ...

The original version of this story appeared in Quanta Magazine. 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 ...

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.
