Direct Known Subclasses:

CautiousArgumentationAgent

public class OvercautiousArgumentationAgent
extends SasAgent

Constructor Detail

OvercautiousArgumentationAgent

public OvercautiousArgumentationAgent(net.sf.tweety.arg.saf.syntax.StructuredArgumentationFramework view,
                                      UtilityFunction utility,
                                      net.sf.tweety.logics.pl.syntax.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.

utility - a utility function.

focalElement - the focal element of this agent.

OvercautiousArgumentationAgent

public OvercautiousArgumentationAgent(net.sf.tweety.arg.saf.syntax.StructuredArgumentationFramework view,
                                      UtilityFunction utility,
                                      boolean isSingleStep,
                                      net.sf.tweety.logics.pl.syntax.Proposition focalElement)

Creates a new agent with the given (local) view and utility function.

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.

next

public net.sf.tweety.agents.Executable next(Collection<? extends net.sf.tweety.agents.Perceivable> percepts)

Overrides:

next in class SasAgent

attackSet

protected Set<net.sf.tweety.arg.dung.syntax.Argument> attackSet()

Computes the attack set of this agent's focal element wrt. its view, i.e. the set of basic arguments "arg" such that there are argumentation structures "AS1" and "AS2" with "arg" in "AS1", "AS1" indirectly attacks "AS2" and the claim of "AS2" is the agent's focal element.

Returns:

the attack set of this agent's focal element wrt. its view.
