In graph theory, reachability refers to the ability to get from one vertex to another within a graph. A vertex $${\displaystyle s}$$ can reach a vertex $${\displaystyle t}$$ (and $${\displaystyle t}$$ is reachable from $${\displaystyle s}$$) if there exists a sequence of adjacent vertices (i.e. a walk) which starts with See more Algorithms for determining reachability fall into two classes: those that require preprocessing and those that do not.
