Parallel dijkstra algorithm

WebWell simply explained, an algorithm that is used for finding the shortest distance, or path, from starting node to target node in a weighted graph is known as Dijkstra’s Algorithm. This algorithm makes a tree of the shortest path from the starting node, the source, to all other nodes (points) in the graph. WebMeyer et al. proposed an optimized Dijkstra’s algorithm, which is a parallel version for a large class of graphs [26]. The best parallel version of the delta-stepping Dijkstra’s algorithm takes ( · ·log +log2 )time and ( + + · ·log )work on average, where denotes the
