The automata-based approach [45] reduces the model checking problem to the graph-theoretic problem of checking the reachability of accepting cycles. Reachability of accepting cycles in directed graphs can be checked in linear time, with the nested depth-first search (NDFS) algorithm [13,19,41],...
After some time, most people will probably find some way to implement this. But here is a simple way using the DFS tree: give each back-edge an unique index starting from N+1N+1; for each vertex uu, calculate the index of the back-edge uu is under; call that cycleId[u]cycleId[u...
Is it possible to execute all the tasks in G in an order that respects all the precedence requirements given by the graph edges? The answer is "yes" if and only if the directed graph G has no cycle! (otherwise we have a deadlock) ...

Looking at the graph depiction below you will also notice the inclusion of a cycle, by the adjacent connections between ‘F’ and ‘C/E’. This has been purposely included to provide the algorithms with the option to return multiple paths between two desired nodes. ...
