Evaluation of Opponent’s Offer Sample Clauses

Evaluation of Opponent’s Offer. This mechanism is carried out each time the team mediator receives an offer from the opponent. Since the main goal of the proposed intra-team strategy is achieving unanimously acceptable agreements for the team, a unanimity voting is carried out to de- cide whether or not the opponent’s offer is accept- able for the team. With this mechanism, as long as one of the team members is not satisfied with the opponent’s offer, the offer is not accepted by the team, precluding the team from reaching agree- ments that are not unanimously acceptable. A for- malization of the protocol followed in this mech- anism can be observed in Figure 4. The picture shows the formalization employing sequence dia- grams from Agent UML. The intra-team protocol used for this mechanism goes as follows. First, the team mediator receives the offer Xt from the op- ponent at time t. If Xt involves any forbidden un- predictable partial offer in FA, the opponent offer is automatically rejected. However, the opponent’s offer is also informed to team members in order to allow each team member to process the new infor- mation leaked by the opponent if they see it nec- ▇▇▇▇▇▇ (message 1 in Figure 4). Otherwise, if the combination of unpredictable issue values is not in FA, in order to see whether the offer is unanimously acceptable for team members, the mediator makes the opponent’s offer public among team members and starts an anonymous voting process (message 2 in Figure 4). Each team member a A states to the mediator whether he is willing to accept Xt (positive vote) or to reject it (negative vote) at that specific instant (messages 3.a or 3.b in Figure 4). Since our aim is to guarantee unanimity, the offer is only accepted if all of the team members emit a positive vote (message 4.a in Figure 4). Otherwise, the offer is rejected and a counter-offer is proposed as explained in Section 3.2.2. ∈
