Example text

If the offer at t = 1 gets rejected, then negotiation goes to the next round. At t = 2, the offering agent (say an agent a of type i) finds OPTA(i, 2) with the updated beliefs. This process of updating beliefs and making offers continues until either an agreement is reached or one of the agents quits negotiation. Theorem 7. If [xt , y t ] denotes the offer made at time t, then for the PD procedure, for the time period t ≤ Nr , the following strategies form a sequential equilibrium: ⎧ ⎪ QUIT if t > Ni ⎪ ⎪ ⎪ ⎪ ⎪ OFFER TRADEOFFA ( EUB (ψ, t)) if a’s turn ⎨ A (i, t) = If offer gets rejected UPDATE BELIEFS ⎪ ⎪ ⎪ RECEIVE OFFER and UPDATE BELIEFS if b’s turn ⎪ ⎪ ⎪ ⎩ If (Uia ([xt , y t ], t) ≥ EUA(i, t)) ACCEPT else REJECT (7) ⎧ ⎪ QUIT if t > Ni ⎪ ⎪ ⎪ ⎪ ⎪ OFFER TRADEOFFB ( EUA (φ, t)) if b’s turn ⎨ B (i, t) = If offer gets rejected UPDATE BELIEFS ⎪ ⎪ ⎪ if a’s turn ⎪RECEIVE OFFER and UPDATE BELIEFS ⎪ ⎪ ⎩ If (Uib ([xt , y t ], t) ≥ EUB(i, t)) ACCEPT else REJECT (8) for 1 ≤ i ≤ r.

In AAMAS ’02, pages 69–76, New York, NY, USA, 2002. ACM Press. On Efficient Procedures for Multi-issue Negotiation Shaheen S. Fatima1 , Michael Wooldridge1, and Nicholas R. uk Abstract. This paper studies bilateral, multi-issue negotiation between self interested agents with deadlines. There are a number of procedures for negotiating the issues and each of these gives a different outcome. Thus, a key problem is to decide which one to use. Given this, we study the three main alternatives: the package deal, the simultaneous procedure, and the sequential procedure.

4 Multi-issue Negotiation with Uncertainty About Deadlines Here, there is uncertainty about the agents’ deadlines. Both agents have a probability distribution over the possible values for na and nb . Let N ∈ Nr denote a vector of r integers such that for 1 ≤ i ≤ r − 1, Ni < Ni+1 . , there are r types for a and r types for b). Let P a : N+ → R1 denote the discrete probability distribution function for na and P b : N+ → R1 that for nb . The vector N and the functions P a and P b are common knowledge to the agents.
