Implementation of the Particle Swarm Optimization (PSO) algorithm to find the shortest path between two given points, avoiding all obstacles ...

Finding the shortest path in a network can sometimes be done by inspection, particularly when the network is simple. However, as the complexity of the network increases, a more systematic approach is ...

Among these, shortest path queries are instrumental in identifying the most efficient routes within a network, thereby reducing cost, time and resource consumption.

In such cases, the fastest known shortest-path algorithm doesn’t work. For decades, fast algorithms for finding shortest paths on negative-weight graphs have remained elusive.

In this note we present some computational evidence to suggest that a version of Bellman's shortest-path algorithm outperforms Treesort-Dijkstra's for a certain class of networks ...
