The Reachability Problem for Petri Nets is Not Elementary

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.
