Abstract

In computer aided verification, the reachability problem is particularly relevant for safety analyses. Given a regular tree language L, a term t and a relation R, the reachability problem consists in deciding whether there exist a positive integer n and terms t"0,t"1,...,t"n such that t"0@?L, t"n=t and for every 0=
