As we draw closer to Christmas and winter sets in, the days become shorter and darker, with the winter solstice marking the shortest day of the year. But when exactly is the shortest day of the year, ...

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 ...

Given an unweighted graph represented using adjacency lists and a source vertex s, compute the shortest path from the source vertex to all other vertices.

Mississippi has the shortest life expectancy rate in the U.S., report finds. Hush Naidoo Jade via Unsplash Mississippi is ranked among the least healthy states in the country and has the lowest life ...

Traditional path planning algorithms often face problems such as local optimum traps and low monitoring efficiency in agricultural UAV operations, making it difficult to meet the operational ...

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.

Unmanned surface vehicles (USVs) nowadays have been widely used in ocean observation missions, helping researchers to monitor climate change, collect environmental data, and observe marine ecosystem ...
