class scml.std.agents.aspiration.SingleAgreementAspirationAgent(*args, **kwargs)

Bases: scml.oneshot.agent.OneShotSyncAgent

Uses a time-based strategy to accept a single agreement from the set it is considering.

before_step()

Called at the beginning of every step.

Remarks:

• Use this for any proactive code that needs to be done every simulation step.

counter_all(offers, states)

Calculate a response to all offers from all negotiators (negotiator ID is the key).

Parameters:

• offers – Maps negotiator IDs to offers

• states – Maps negotiator IDs to offers AT the time the offers were made.

Returns:

A dictionary mapping negotiator ID to an SAOResponse. The response per agent consist of a tuple. In case of acceptance or ending the negotiation the second item of the tuple should be None. In case of rejection, the second item should be the counter offer.

Remarks:

• The response type CANNOT be WAIT.

• If the system determines that a loop is formed, the agent may

receive this call for a subset of negotiations not all of them.

choose_agents(offers, outcome)

Selects an appropriate way to distribute this outcome to agents with given IDs.

first_proposals() → Dict[str, negmas.Outcome | None]

Gets a set of proposals to use for initializing the negotiation.

Returns:

A dictionary mapping each negotiator (in self.negotiators dict) to an outcome to be used as the first proposal if the agent is to start a negotiation.
