WebAnd detect a cycle in the process DFS based algorithm: 1. Compute DFS(G) 2. If there is a back edgee = ( v, u) then G is not a DAG. Output cycle C formed by path from u to v in T plus edge (v, u). 3. Otherwise output nodes in decreasing post-visit order. Note: no need to sort, DFS (G) can output nodes in this order. WebJun 24, 2024 · In Kruskal’s algorithm, the crucial part is to check whether an edge will create a cycle if we add it to the existing edge set. There are several graph cycle detection algorithms we can use. For example, we can use a depth-first search (DFS) algorithm to traverse the graph and detect whether there is a cycle.
