Abstract: The shortest path problem is a widely recognized and fundamental optimization problem in operations research. Nearly all practical implementations of the shortest path issue include ...

This past spring, a biotech company announced the first use of a new gene-editing technology in people to fix an errant gene that causes a severe immune disorder. In June, a baby born with a ...

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 ...

The All-Pairs Shortest Paths Problem, Seeking the Shortest Distance Between Every Node Pair in a Graph, is Efficiently Solved by Johnson's Algorithm for All Pairs of a Vertext, Bellman-Ford for ...

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 ...

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.

PATH riders using Hoboken Terminal will be offered free or discounted rides on NJ Transit and NY Waterway ferries starting Tuesday due to repairs of Hoboken switch problems blamed for a July 12 ...

Sometimes you can hear a French bulldog before you see it—it’s the wheezing sounds they make when they breathe. Frenchies, it seems, are 30 times more likely than other breeds to suffer from ...

The original version of this story appeared in Quanta Magazine. For computer scientists, solving problems is a bit like mountaineering. First they must choose a problem to solve—akin to identifying a ...
