utilityFunction - the utility function of the agent.

Method Detail

update

public void update(DialogueTrace<Argument,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

sampleT1BeliefState

public T1BeliefState sampleT1BeliefState()

Returns a T1-belief state that is a projection of this belief state, i.e. in every nested model one substate is chose randomly depending on its probability

Returns:

a T1-projection of this belief state.

doMove

protected Pair<java.lang.Double,java.util.Set<ExecutableExtension>> doMove(ArgumentationEnvironment env,
                                                                                 DialogueTrace<Argument,Extension> trace)

Description copied from class: BeliefState
