A method for finding shortest paths (routes) in a network. The algorithm is a node labeling, greedy algorithm. It assumes that the distance cij between any pair of nodes i and j is nonnegative. The laGass, SaulHarris, Carl

By designing a suitable SuccessorsFunc function, and taking advantage of function captures and the variable node_id type, you can apply Dijkstra's algorithm to scenarios that would otherwise be difficult to model as a graph. In my experience, the most difficult part of applying Dijkstra from a...
So, GA has the potential to replace DA in finding the shortest path for Network Topologies. Simulation results are performed for both Algorithms on MATLAB and GENETIC ALGORITHM TOOL.Y. SharmaS.C. SainiM. BhandhariBuldanshahr : IJECSEinternational journal of electronics & computer science ...
