Abstract

Given a distributed computation and a predicate, detection of the predicate in $\mathit{Definitely}$ modality means checking whether in every path from the least state to the greatest state in the state space generated from the computation, there exists a state satisfying the predicate. It is well known that the state space is a lattice. The regular predicate is a class of predicates. All the states satisfying a regular predicate form a sublattice of the lattice. In this paper, we prove that detection of a regular predicate in $\mathit{Definitely}$ modality is coNP-complete.
