Jan Kyncl, Tomas Vyskocil#### Logspace reduction of directed reachability for bounded genus graphs to the planar case

Jan Kyncl, Tomas Vyskocil

Directed reachability (or briefly reachability) is the following decision problem: given a directed graph G and two of its vertices s,t, determine whether there is a directed path from s to t in G. Directed reachability is a standard complete problem for the complexity class NL. Planar reachability is an ... more >>>
