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 ...

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 ...

SPECIAL ISSUE NO. 106. Advances in Coastal Research: Engineering, Industry, Economy, and Sustainable Development (SUMMER 2020), pp. 251-254 (4 pages) Published By: Coastal Education & Research ...

Sometimes, wrapping your head around mathematical concepts can be tricky without a visual aid. Thankfully we have makers like ...

The paper considers a project scheduling problem in weighted directed graphs in which arcs represent operations while nodes are identified with starting and finishing endpoints of the operations; arc ...

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.
