WebJan 13, 2014 · 1. For non-negative edge weighted graph, Dijkstra's algorithm will always find the shortest path. So it's impossible in non-negative weighted graph. However, in graph with negative edge weighted, Dijkstra's doesn't guarantee the shortest path, it maybe return a greater-cost path than DFS. Share.
WebMay 31, 2011 · Uniform Cost Search (UCS): modifies BFS by always expanding the lowest cost node on the fringe using path cost function g (n) (i.e. the cost of the path from the initial state to the node n).
