Abstract: In real-world scenarios, computing the shortest path between given source and destination is widely prevalent, such as seeking the optimal route in a road network for navigation. However, in ...
OpenAI announced Thursday that it has entered into an agreement to acquire Astral, the company behind popular open source Python development tools such as uv, Ruff, and ty, and integrate the company ...
"Breaking the Sorting Barrier for Directed Single-Source Shortest Paths" by Ran Duan, Jiayi Mao, Xiao Mao, Xinkai Shu, and Longhui Yin (2025) Use the road_network_benchmark example to evaluate the ...
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 ...
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 ...
Python simulation of the London Underground network that finds the fastest route between stations using weighted graph algorithms. Includes dynamic connections and optimization for travel time and ...
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 ...
It works well. But there’s a problem—every time you discover a new road, you need to re-sort your list. That re-sorting adds hidden time. They don’t bother sorting at all. Instead, they just keep ...
Abstract: Single-Source Shortest Path (SSSP) is a fundamental graph problem that arises in various applications and complex problems. State-of-the-art solutions to the parallel SSSP problem create ...
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 ...
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 ...
The shortest path problem in graph theory is the task of determining the path between any two vertices (or nodes) in a graph such that the sum of the weights along each of its constituent edges is as ...
