WebApr 12, 2024 · No, we cannot use union-find to detect cycles in a directed graph. This is because a directed graph cannot be represented using the disjoint-set (the data structure on which union-find is performed). When we say 'a union b' we cannot make out the direction of edge is a going to b? (or) is b going to a?

WebApr 6, 2024 · The first is union-find, which is said to have a time complexity of O (Vlog E). The second uses a DFS based approach and is said to have a time complexity of O (V+E). If I am correct this is a more efficient complexity asymptotically than O (Vlog E). It is also convenient that the DFS-based approach can be used for directed and undirected graphs. WebIn the recursive DFS, we can detect a cycle by coloring the nodes as WHITE, GRAY and BLACK as explained here. A cycle exists if a GRAY node is encountered during the DFS search. My question is: When do I mark the nodes as GRAY and BLACK in this iterative version of DFS? (from Wikipedia)
WebSuppose you are given a directed, weighted graph with negative cycles. Can you modify the Bellman-Ford algorithm to detect and output the nodes that are part of any negative cycle or are reachable from a negative cycle? If yes, explain the modifications you would make to the original algorithm and justify why the proposed solution works.
