  • Publication number: 20250095041
    Abstract: A negotiation apparatus acquires history information that indicates a proposal time of a current offer from an opponent agent and a utility of each offer from the opponent agent that has been received in a negotiation. In the negotiation, a maximum length of time of the negotiation period is fixed in advance. The negotiation apparatus generates a probability distribution of the number of future offers based on the length of time of the remaining period of the negotiation and the proposal time of the current offer. The negotiation apparatus computes an expected utility of future offers based on the probability distribution of the number of future offers and the utilities indicated by the history information. The negotiation apparatus determines whether or not to accept the current offer based on the expected utility of future offers and the utility of the current offer.
