Dijkstra algorithm java

WebOct 8, 2012 · Edge relaxation. To relax an edge v -> w means to test whether the best-known way from s to w is to from s to v, then take the edge from v to w, and, if so, update our data structures. There is also vertex relaxation. That means to relax all the edges pointing from a given vertex. WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
