Detect and print cycle in directed graph
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. Weband c elementary circuits in the graph. The algorithm resembles algorithms by Tiernan and Tarjan, but is faster because it considers each edge at most twice between any one circuit and the next in the output sequence.

WebSep 26, 2024 · Consider a directed or undirected graph without loops and multiple edges. We have to check whether it is acyclic, and if it is not, then find any cycle. ... If DFS moves to a gray vertex, then we have found a cycle (if the graph is undirected, the edge to parent is not considered). The cycle itself can be reconstructed using parent array ...
WebCycle in Directed Graph - Problem Description Given an directed graph having A nodes. A matrix B of size M x 2 is given which represents the M edges such that there is a edge directed from node B[i][0] to node B[i][1]. Find whether the graph contains a cycle or not, return 1 if cycle is present else return 0.
