Bellman Ford's Algorithm is similar to Dijkstra's algorithm but it can work with graphs in which edges can have negative weights. In this tutorial, you will understand the working on Bellman Ford's Algorithm in Python, Java and C/C++.
Dial’s Algorithm (Optimized Dijkstra For Small Range Weights)
Nov 24, 2021 · Can we optimize Dijkstra’s shortest path algorithm to work better than O(E log V) if maximum weight is small (or range of edge weights is small)? For example, in the above diagram, maximum weight is 14. Many a times the range of weights on edges in is in small range (i.e. all edge weight can be mapped to 0, 1, 2.. w where w is a small number).
Dijsktra's Algorithm - GeeksforGeeks
Sep 10, 2021 · Dijkstra’s Algorithm for Adjacency List Representation for more details. 5) Dijkstra’s algorithm doesn’t work for graphs with negative weight cycles. It may give correct results for a graph with negative edges but you must allow a vertex can be visited multiple times and that version will lose its fast time complexity.
