WebI'm looking for an algorithm that given a graph it returns all the minimal cycles in it. To make clear what I want, I need the algorithm to return exactly the following cycles from this graph: (1,3,6,1), (1,6,4,1), (1,4,2,1), (6,4,7,6), (2,4,7,2), (2,7,5,2) I've been searching alot and I still can't figure out even the name of this problem. WebJun 24, 2024 · 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. However, we need to do a cycle detection on existing edges each time when we test a new edge.
