Author(s): Carlo Carraro, Carmen Marchiori, Alessandra Sgobbi

Summary:
Discusses the classical theory of negotiation (bilateral, single issue, complete information) Rubinstein alternating offer game. The paper then goes on to discuss multi-player, multi-issue particularly sequential bidding with bargaining agendas, bargaining in stochastic environment and repeated bargaining. Also goes into coalition forming and “fairness” (however not very relevent for discount factors).

Multi-issue Negotiation with Deadlines

Author(s): Shaheen Fatima, Michael Wooldridge, Nicholas Jennings

Summary:
Give a brief description of the bilaterla negotiation looking at time constraints (deadline as well as discount factors) Discusses different procedures e.g. package deal (which is my focus), simaltaneous, sequential. In section 3 it discusses the equilibrium in the different procedures and presents theroem s with proofs. In section 4 it discusses a little bit about uncertainty where the utility of the opponent is unknown to the agent.

IAMHAGGLER: A Negotiation Agent for Complex Environment

Author(s): Colin Williams, Valentin Robu, Enrico Gerding, Nicholas Jennings

Summary:
This paper gives a brief description of the strategy and methods the IAMHAGGLER uses. It uses the discount factor to calculate an estimated utility of the opponent. With the use of the discount factor (and other formulas) IAMHAGGLER is able to predict the maximum possible discounted utility at a given time t and si able to determine what sort bid the agent should offer at any given time t. IAMHAGGLER makes a distinction between ordered and unordered issues. With unordered issues it uses baysean learning (choosing an iso-utility space, which is the same as a threshold range for the bids).

Benefits of Learning in Negotiation

Author(s): Dajun Zeng, Katia Sycara

Summary:
Looks at the idea of learning with in a sequential desicion making protocol. They created a protocol called BAZAAR. Lays focus also on the learning of reservation value and how that can be benefitial by creating a better bid exchange (less bids exchanged before agreement is made) and a better joint utiity.
