Constructor Details

RandomAspicReasoner

public RandomAspicReasoner(AbstractExtensionReasoner aafReasoner,
 int maxArguments,
 int maxDuplicates)

Creates a new instance.

Parameters:

aafReasoner - Underlying reasoner for AAFs.

maxArguments - The maximal number of arguments constructed by this reasoner.

maxDuplicates - The maximal number of duplicates tolerated before this reasoner cancels looking for more arguments (even if maxArguments is not yet reached).
