The new algorithm handles changes consisting of deleted edges -- for example, if the equivalent ... The version of the "shortest path" problem that the researchers solved is called "The ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

Following a similar design process, we will design efficient algorithms for a sequence of problems: shortest paths, minimal cycle ratios, maximal network flows, min-cost flows, and convex cost flows.

In many situations, an object's priority is implied. For example, in a graph-based shortest-path algorithm, items have a distance field that acts as the priority. Priority fields are almost always ...
