Detect cycle in undirected graph in c

WebDetect Cycle in a Directed Graph using BFS. We can also check whether the given graph has any cycles or not using the breadth-first search algorithm. The idea is to traverse the graph using BFS and check any path being repeated. If so, there is a circle in the graph. We use an additional Vertex variable ( parent) to keep track of traversed paths. WebSep 11, 2024 · So, to detect a cycle in an undirected graph, we can use the same idea. The algorithm would be: For each edge in the edge list: Find parents(set name) of the source and destination nodes respectively (Though we are using terms like source & destination node, the edges are undirected).
