Method Details

satisfies

public boolean satisfies(ProbabilisticExtension p,
 DungTheory theory)

Description copied from interface: PASemantics

Checks whether the given probabilistic extension satisfies the given argumentation theory wrt. this semantics.

Specified by:

satisfies in interface PASemantics

Specified by:

satisfies in class AbstractPASemantics

Parameters:

p - a probabilistic extension.

theory - an argumentation theory

Returns:

"true" iff the given distribution satisfies the given conditional.

getSatisfactionStatements

public Collection<Statement> getSatisfactionStatements(DungTheory theory,
 Map<Collection<Argument>,FloatVariable> worlds2vars)

Description copied from interface: PASemantics

Returns the mathematical statement corresponding to the satisfaction of the given theory wrt. this semantics.

Specified by:

getSatisfactionStatements in interface PASemantics

Specified by:

getSatisfactionStatements in class AbstractPASemantics

Parameters:

theory - an argumentation theory.

worlds2vars - a map mapping the (probabilities of the) extensions to mathematical variables (for constructing the statement).

Returns:

the mathematical statement corresponding to the satisfaction of the given theory wrt. this semantics.
