WebDec 11, 2016 · An undirected graph is basically just a directed graph, but with bidirectional connections. So no, Dijkstra's can also be applied to directed graphs. For weakly connected graphs, it depends. Say you have graph section A and graph section B. You can go from A into B, but not from B into A. WebOn non-negative weighted graphs, the behavior of Modified Dijkstra's implementation is exactly the same as the Original Dijkstra's so we can use the same time complexity analysis of O((V+E) log V). PS: We note that when we use the Modified Dijkstra's algorithm, there can be more items (up to E ) in the Priority Queue than if we use the Original ...
