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. WebThough Minimum Spanning Tree and Shortest Path algorithms computation looks similar they focus on 2 different requirements. In MST, requirement is to reach each vertex once (create graph tree) and total (collective) cost of reaching each vertex is required to be minimum among all possible combinations. In Shortest Path, requirement is to reach ...

WebJan 18, 2024 · Breadth first search is one of the basic and essential searching algorithms on graphs.
