counter_all(offers, states)[source]

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.

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.

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

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

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