Dijkstra's algorithm O((n+m)log(n)). Used to find the shortest distance from one node to every other node in a graph. Inputs: - DAG G=(V,E) with edge weights - Source vertex s Output: - Array dist[...] that tells us the length of the shortest path from s to each other vertex. e.g. dist[v] gives us the distance of s to v Kruskal's Algorithm O(mlog(n)) Minimum Spanning Tree builder. "Repeatedly add the next lightest edge that doesn't produce a cycle". Inputs: - Graph G=(V,E) with...

DFS outputs - Answer-pre array, post array, ccnum array, prev array BFS outputs - Answer-dist array, prev array Explore outputs - Answer-visited array When to use Dijkstra's? - Answer-Use on both directed and undirected graphs to find the shortest path from a source vertex to all other reachable vertices in the graph. Must have only non-negative edge weights. Dijkstra's outputs - Answer-dist array, prev array Dijkstra's time complexity - Answer-O((n+m) log n) log n is from using the m...
