Method Details

isApplicable

public boolean isApplicable(Collection<PlFormula> kb)

Description copied from interface: Postulate

Checks whether the given kb represents a non-trivial instance for this postulate, i.e., whether assumptions of this postulates are satisfied (evaluating an approach on a non-applicable instance always succeeds).

Specified by:

isApplicable in interface Postulate<PlFormula>

Specified by:

isApplicable in class ImPostulate

Parameters:

kb - some knowledge base

Returns:

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

isSatisfied

 BeliefSetInconsistencyMeasure<PlFormula> ev)

Description copied from class: ImPostulate

Return whether the formulas are satisfied

Specified by:

isSatisfied in class ImPostulate

Parameters:

kb - collection of formulas

ev - BeliefSet Inconsistency Measure

Returns:

whether the formulas are satisfied

getName

public String getName()

Description copied from interface: Postulate

The textual name of the postulate

Returns:

a string
