public class RelationalProbabilisticConditional
extends RelationalConditional

This class represents a relational probabilistic conditional, i.e. a structure (B|A)[p] with first-order formulas A and B and a probability p.

Premise and conclusion of this conditional must confirm to a fol language without quantifiers and without functions (@see net.sf.tweety.logics.firstorderlogic.lang.FolLanguageNoQuantifiersNoFunctions)

                                          FolFormula conclusion,
                                          Probability probability)

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

Parameters:

premise - a fol formula.

conclusion - a fol formula.

probability - a probability.

RelationalProbabilisticConditional

public RelationalProbabilisticConditional(FolFormula conclusion,
                                          Probability probability)

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

Parameters:

conclusion - a fol formula.

probability - a probability.

RelationalProbabilisticConditional

public RelationalProbabilisticConditional(RelationalConditional conditional,
                                          Probability probability)

Creates a new relational probabilistic conditional with the given conditional and probability

Parameters:

conditional - a relational conditional.

probability - a probability.

Method Detail

getProbability

public Probability getProbability()

Returns the probability of this conditional.

Returns:

the probability of this conditional.

substitute

public RelationalFormula substitute(Term<?> v,
                                    Term<?> t)
                             throws java.lang.IllegalArgumentException

Description copied from class: RelationalFormula

Substitutes all occurrences of term "v" in this formula by term "t" and returns the new formula. NOTE: if "v" is a variable and bound to a quantifier then "v" is not substituted in that quantifiers inner formula.

Specified by:

substitute in interface ComplexLogicalFormula

Overrides:

substitute in class RelationalConditional

Parameters:

v - the term to be substituted.

t - the term to substitute.

Returns:

a formula where every occurrence of "v" is replaced by "t".

Throws:

java.lang.IllegalArgumentException - if "v" and "t" are of different sorts (NOTE: this exception is only thrown when "v" actually appears in this formula).

toString

public java.lang.String toString()

Overrides:

toString in class RelationalConditional

complement

public RelationalProbabilisticConditional complement()

Specified by:

complement in interface Invertable

Overrides:

complement in class RelationalConditional

Returns:

the complement of this formula.

hashCode

public int hashCode()

Specified by:

hashCode in interface SimpleLogicalFormula

Overrides:

hashCode in class RelationalConditional

equals

public boolean equals(java.lang.Object obj)

Specified by:

equals in interface SimpleLogicalFormula

Overrides:

equals in class RelationalConditional
