Method Details

isApplicable

public abstract 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>

Parameters:

kb - some knowledge base

Returns:

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

isSatisfied

public boolean isSatisfied(Collection<PlFormula> kb,
 PostulateEvaluatable<PlFormula> 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<PlFormula>

Parameters:

kb - some knowledge base

ev - some approach

Returns:

true if the postulate is satisfied on the instance

isSatisfied

public abstract boolean isSatisfied(Collection<PlFormula> kb,
 BeliefSetInconsistencyMeasure<PlFormula> ev)

Parameters:

kb - collection of formulas

ev - BeliefSet Inconsistency Measure

Returns:

whether the formulas are satisfied
