Can a path repeat vertices

WebIn the case of a road map, if you want to find the shortest route between two locations, you're looking for a path between two vertices with the minimum sum of edge weights over all paths between the two vertices. As with … WebApr 6, 2024 · Dijkstra’s algorithm is a well-known algorithm in computer science that is used to find the shortest path between two points in a weighted graph. The algorithm uses a priority queue to explore the graph, assigning each vertex a tentative distance from a source vertex and then iteratively updating this value as it visits neighboring vertices.
