The shortest covering path (SCP) problem involves finding the shortest path between an origin node and a destination node, where the path traverses the network and passes within a maximal covering distance of al...

“cloud” of vertices, v from a vertex s is the length beginning with s and eventually of a shortest path between s and v covering all the vertices We store with each vertex v a Dijkstra’s algorithm computes label d(v) representing the the distances of all the distance of v from s ...

Quantitative rules covering the first two factors have been derived indicating that the fastest algorithm will be: (1) Dijkstra for networks where d/N nodes < c 1 ; (2) Moore if N nodes < c 2 ; (3) D'Esopo under all other conditions. c 1 and c 2 are parameters 0.02 and 75 ...
For this problem, we propose a polynomial time approximation algorithm based on iteratively constructing shortest path trees and heuristically pruning away the relay nodes used until the hop count bound is violated. Results show that the algorithm performs efficiently in various randomly generated network...
nodes (i 1 , i 2 , . . . , i k ) such that (i q , i q+1 ) is an arc for all q = 1, . . . , k −1. If in addition the nodes i 1 , i 2 , . . . , i k are distinct, the sequence (i 1 , i 2 , . . . , i k ) is called a simple path. A seq...
A demand is counted as covered if the total arc length of a path from the demand to a facility site is within coverage distance and the demand can be satisfied only if all the intermediate demand nodes on the path are satisfied.;Computational results for networks selected from literature show...
