LTK.Decide.PT

Description

This module implements an algorithm to decide whether a given FSA is Piecewise Testable (PT) based on the semigroup characterization of Simon from his 1975 work "Piecewise testable events".

Since: 0.2

Synopsis

isPT :: (Ord n, Ord e) => FSA n e -> Bool
isPTM :: (Ord n, Ord e) => SynMon n e -> Bool

Documentation

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

True iff the automaton recognizes a PT stringset.

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

True iff the monoid is \(\mathcal{J}\)-trivial
