2.5 Shortest Path Model To run the Linear Programming model, the shortest path d(i, j) need to be calculated. We could simply tackle the problem employing a iterative algorithm(Dijkstra, 1959)[5]. This problem sets reads the tree of minimum total length between n nodes, and the path of...

Goel [45] used PIOA to search for the shortest path from a given point and measured the efficiency of the approach using Dijkstra’s algorithm. Hao et al. [46] enhanced the basic PIOA to solve the unmanned aerial vehicle (UAV) assignment problem under energy consumption. Sun and Duan [...
* to gain significant performance boosts. For example, Dijkstra's algorithm * for single-source shortest paths can be shown to run in O(m + n lg n) using * a Fibonacci heap, compared to O(m lg n) using a standard binary or binomial ...
