public class CautiousArgumentationAgent
extends OvercautiousArgumentationAgent

CautiousArgumentationAgent

public CautiousArgumentationAgent(StructuredArgumentationFramework view,
                                  UtilityFunction utility,
                                  Proposition focalElement)

Creates a new (non-single-step) agent with the given (local) view and utility function.

Parameters:

view - the view of the agent on the argumentation.

focalElement - the focal element of this agent.

CautiousArgumentationAgent

public CautiousArgumentationAgent(StructuredArgumentationFramework view,
                                  UtilityFunction utility,
                                  boolean isSingleStep,
                                  Proposition focalElement)

Parameters:

view - the view of the agent on the argumentation.

utility - a utility function.

isSingleStep - indicates whether this agent is a single-step argumentation agent, i.e. whether he may bring forward only one argument at a time or multiple.

focalElement - the focal element of this agent.

Method Detail

next

public Executable next(java.util.Collection<? extends Perceivable> percepts)

Description copied from class: Agent

Determines the next action of this agent wrt. the given percepts.

Overrides:

next in class OvercautiousArgumentationAgent

Parameters:

percepts - a collection of percepts.

Returns:

an action.

necessaryArguments

protected java.util.Set<Argument> necessaryArguments()

Computes the set of necessary arguments for this agent's focal element, i.e. the intersection of all argument structures claiming this agent's focal element.

Returns:

the set of necessary arguments for this agent's focal element.
