Description

This module implements an algorithm to decide whether a given FSA is generalized locally testable in the sense of Brzozowski and Fich (1984): https://doi.org/10.1016/0012-365X(84)90045-1

Since: 1.0

Synopsis

isGLT :: (Ord n, Ord e) => FSA n e -> Bool
isGLTM :: (Ord n, Ord e) => SynMon n e -> Bool
isGLTs :: FiniteSemigroupRep s => s -> Bool

Documentation

isGLT :: (Ord n, Ord e) => FSA n e -> Bool #

True iff the automaton recognizes a generalized locally-testable stringset.

isGLTM :: (Ord n, Ord e) => SynMon n e -> Bool #

True iff the monoid satisfies the generalized local testabiltiy condition.

isGLTs :: FiniteSemigroupRep s => s -> Bool #

True iff the semigroup lies in \(M_e J_1\).
