de.learnlib.counterexamples.acex

Class ClassicPrefixTransformAcex<I,D>

java.lang.Object

de.learnlib.acex.impl.AbstractBaseCounterexample<Boolean>

de.learnlib.counterexamples.acex.ClassicPrefixTransformAcex<I,D>

Type Parameters:

I - input symbol type

D - output domain type

All Implemented Interfaces:

AbstractCounterexample<Boolean>

public class ClassicPrefixTransformAcex<I,D>
extends AbstractBaseCounterexample<Boolean>

An abstract counterexample based on prefix transformations. Unlike OutInconsPrefixTransformAcex and its derivatives, the effect of this abstract counterexamples is not directly determined by the system outputs, but instead by whether they match the hypothesis output or not (as described in the paper An Abstract Framework for Counterexample Analysis in Active Automata Learning (M. Isberner, B. Steffen; Proc. ICGI 2014).
