Method Detail

isApplicable

public abstract boolean isApplicable(java.util.Collection<Argument> kb)

The INCREASEOFDEFENSEBRANCH postulate

Specified by:

isApplicable in interface Postulate<Argument>

Parameters:

kb - some knowledge base

Returns:

true if the knowledge base is a non trivial instance of this postulate.

isSatisfied

public boolean isSatisfied(java.util.Collection<Argument> kb,
                           PostulateEvaluatable<Argument> ev)

Description copied from interface: Postulate

Checks whether this postulate is satisfied by the given approach ev wrt. the given instance kb (note that evaluating an approach on a non-applicable instance always succeeds).

Specified by:

isSatisfied in interface Postulate<Argument>

Parameters:

kb - some knowledge base

ev - some approach

Returns:

true if the postulate is satisfied on the instance

isSatisfied

public abstract boolean isSatisfied(java.util.Collection<Argument> kb,
                                    AbstractRankingReasoner<ArgumentRanking> ev)
