WebApr 9, 2024 · The Dijkstra’s Algorithm is an algorithm that is used to find the shortest path between two cities on a map or otherwise in programming the shortest path between two nodes in a graph. This algorithm works on graphs that don’t have negative weights on the edges so otherwise, it will not print the correct result. The core idea of the Dijkstra algorithm is to continuously eliminate longer paths between the starting node and all possible destinations. To keep track of the process, we need to have two distinct sets of nodes, settled and unsettled. Settled nodes are the ones with a known minimum distance from the … See more The emphasis in this article is the shortest path problem (SPP), being one of the fundamental theoretic problems known in graph theory, and how the Dijkstra algorithmcan be used to solve it.
