Cs6515 graph algorithms - Study guides, Class notes & Summaries

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-Works for both directed and undirected graphs. Must have only non-negative edge weights. Dijkstra's outputs - ANSWER-dist array, prev array Dijkstra's runtime? - ANSWER-O((n+m) log n) log n is from using the min heap (to get the lowest cost weight) When to use Bellman Ford? - ANSWER-Use when there is a ...

How do you tell if a graph has negative edges? - ANSWER-when fitting graph on a table, if the number of moves decreases the w() from edge to edge, then there is a negative edge; check from 1 to n Why are all pairs Dist(y,z) n^2? - ANSWER-Because it builds a two dim table! What is the run time of bellman ford algorithm? How about if you had to do it for all edges? - ANSWER-O(nm) O(n^2m) Floyd-Warshall run time? - ANSWER-O(n^3) What is the base case for the bellman ford algorithm? - ANSWE...
