rec - the recognition function

prob - the probability function over opponent models.

Method Detail

update

public void update(DialogueTrace<net.sf.tweety.arg.dung.syntax.Argument,net.sf.tweety.arg.dung.semantics.Extension> trace)

Description copied from class: BeliefState

Updates the current belief state accordingly to the given dialogue trace.

Specified by:

update in class BeliefState

Parameters:

trace - a dialogue trace

doMove

protected net.sf.tweety.commons.util.Pair<Double,Set<ExecutableExtension>> doMove(ArgumentationEnvironment env,
                                                                                        DialogueTrace<net.sf.tweety.arg.dung.syntax.Argument,net.sf.tweety.arg.dung.semantics.Extension> trace)

Description copied from class: BeliefState
