r igraph find all cycles
问题 I have directed igraph and want to fetch all the cycles. girth function works but only returns the smallest cycle. Is there a way in R to fetch all the cycles in a graph of length greater then 3 (no vertex pointing to itself and loops) 回答1: It is not directly a function in igraph, but of course you can code it up. To find a cycle, you start at some node, go to some neighboring node and then find a simple path back to the original node. Since you did not provide any sample data, I will
