Reachability problem
Reachability is a fundamental problem that appears in several different contexts: finite- and infinite-state concurrent systems, computational models like cellular automata and Petri nets, program analysis, discrete and continuous systems, time critical systems, hybrid systems, rewriting systems, probabilistic … See more Finite explicit graph The reachability problem in an oriented graph described explicitly is NL-complete. Reingold, in a 2008 article, proved that the reachability problem for a non-oriented graph is in LOGSPACE. See more The International Conference on Reachability Problems series, previously known as Workshop on Reachability Problems, is an annual academic conference which … See more 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
