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. WebTrue or false: For graphs with negative weights, one workaround to be able to use Dijkstra’s algorithm (instead of Bellman-Ford) would be to simply make all edge weights positive; for example, if the most negative weight in a graph is -8, then we can simply add +8 to all weights, compute the shortest path, then decrease all weights by -8 to return to the …
