java.lang.Object

net.sf.tweety.commons.BeliefBaseSampler<PlBeliefSet>

net.sf.tweety.logics.pl.util.MiSampler

public class MiSampler
extends BeliefBaseSampler<PlBeliefSet>

Generates random propositional belief base with a given inconsistency measure (for the MI inconsistency measure) and of a given size. NOTE: this sampler is quite simple and only generates MIs of size four and is very demanding on the size of the signature.

Description copied from class: BeliefBaseSampler

This method randomly samples a single belief base of the given signature with the given belief base length.

Specified by:

randomSample in class BeliefBaseSampler<PlBeliefSet>

Parameters:

minLength - the minimum length of the belief base.

maxLength - the maximum length of the belief base.

Returns:

a single belief base.
