Hi, I'm in doubt in how to check if there's cycles in a graph meanwhile I do a topological sort. The only way to implement a topological sort is this one: voiddfs(intx){vis[x]=true;for(intu=0;u<n;u++){if(!vis[u]&&graph[x][u]==1){dfs(u);}}order.push_back(x);} ...
graphwhereas if there is no closed shape in a circular fashion in a graph then it is called an acyclic graph. If there is a closed shape in an undirected graph, it will definitely be a cycle whereas, for a directed graph, this might not be true. This is also shown in the images ...
In this work we study local checkability of network properties like s-t reachability, or whether the network is acyclic or contains a cycle. A structural property S of a graph G is locally checkable, if there is a prover-and-verifier pair (P, V) as follows. The prover P assigns a ...
