Constructor Detail

ProbabilisticConditional

public ProbabilisticConditional(PlFormula conclusion,
                                Probability probability)

Creates a new probabilistic conditional with a tautological premise and given conclusion and probability.

Parameters:

conclusion - the conclusion (a formula) of this conditional.

probability - a probability.

ProbabilisticConditional

public ProbabilisticConditional(PlFormula premise,
                                PlFormula conclusion,
                                Probability probability)

Creates a new probabilistic conditional with the given premise, conclusion, and probability.

Parameters:

premise - the premise (a formula) of this conditional.

conclusion - the conclusion (a formula) of this conditional.

probability - a probability.

ProbabilisticConditional

public ProbabilisticConditional(Conditional conditional,
                                Probability probability)

Creates a new probabilistic conditional using the given conditional and probability.

Parameters:

conditional - a conditional.

probability - a probability.

Method Detail

qualitativeEquals

public boolean qualitativeEquals(ProbabilisticConditional other)

Checks whether this and the given probabilistic conditional are qualitatively equivalent, i.e. whether they are equivalent when neglecting the probability.

Parameters:

other - some probabilistic conditional.

Returns:

"true" iff the two conditionals are qualitatively equivalent.
