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 ...

Abstract: Counting the number of shortest paths between two query vertices on road networks has a wide range of applications and has recently drawn significant research attention. The state-of-the-art ...

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.

Several factors are causing the length of a day on Earth to change. Tuesday, July 22 will be the second-shortest day of the year, as Earth completes a full rotation in less time than usual. The planet ...

Finding the shortest path in a network is a classical problem, and a variety of search strategies have been proposed to solve it. In this paper, we review traditional approaches for finding shortest ...

Dijkstra’s algorithm is great as long as we have no negative weight edges in our graph. But there are many problems for which it is natural to represent weights with positive and negative values—gains ...
