WebAbstract An algorithm is presented for the general Petri net reachability problem. It is based on a generalization of the basic reachability tree construction which is made symmetric with respect to the initial and final marking. Webputational complexity of the reachability problem for VAS remains one of the most well-known open questions in theoretical computer science. While decidability was still … WebIn general, the all-pairs CFL-reachability problem can be solved in time O(jT [ Nj 3n ) for a graph with n nodes. Figure 2 shows an example of a Dyck-CFL reachability problem. The dashed lines show the edges added by the computation of closure(G). The edges show that there are S-paths between nodes x1 and z1, and x2 and z2. Self-loop chronic urticaria in children
