Author(s)L.D. Serban, G.C. Silaghi, and C.M. Litan
Cited-
Subject(s)Learning issue utility curves by Bayesian learning; Learning issue ordering
SummaryThe opponent model of FSEGA tries to approximate the ordering of the issues and the utility function of each issue by using Bayesian
learning. Each value in an issue is imagined as approximating one of the three basic functions (downhill, uphill, triangular). Using
the Bayesian formula, each hypothesis for a value is updated. Finally the hypothesis are combined based on their likelihood
to determine the final form of the utility function for each value in the issue; combining these results in the utility function for
an issue. Finally, the bidding strategy uses isocurves and the opponent model to increase acceptance.

Cited5
Subject(s)Strategy evaluation
SummaryThe process of the negotiation determines the outcome. This work presents an outline of a formal toolbox to analyze
the dynamics of negotiation based on an analysis of move types. Boulware is a hard bargaining tactic, whereas
conceder is soft. Besides evaluating the outcome one should also analyze the dance. This can be done by
classifying the moves (nice, selfish, etc). A trace is a list of bids. The percentage of a type of move can be
calculated. The sensitivy for opponent moves is based on this measure.

TitleAutomated Multi-Attribute Negotiation with Efficient Use of Incomplete Preference Information
Author(s)C. Jonker and V. Robu
Cited44
Subject(s)Mechanism for taking learning and initial information into account in a standard bilateral negotiation model
SummaryThe classic technique for negotiation with undisclosed preferences is to use a mediator, however
can we be sure that he is impartial? The negotiation strategy discussed is for billeteral multi-issue
negotiation. A decreasing util curve is considered. A bid is calculated to fit the current
util. Each issue has a seperate parameter such that more or less concession can be made on
certain issues. General tolerance determines the general speed of concession. For each issue
for the opponent bid and new calculated bid it is considered how much concession is made
towards the opponent bid based on the configuration tolerance for each issue. This full
formula depends on the weights of the opponent, which have to be estimated. The weights for each
attribute can be estimated by comparing the distance between attributes for an issue in
sequential bids and using this distance to mark the importance of an attribute. This last
step is domain dependent. Concluding, the technique works, but requires tuning for the domain
and assumes that the other agent plays a more or less similiar concession based technique.

Author(s)D. Zeng, K. Sycara
Cited116
Subject(s)Benefits of learning, Bayesian learning, reservation values
Summary Growing interest in e-commerce motivates research in automated negotiation. Building intelligent negotiation agents is still
emerging. In contrast to most negotiation models, sequential decision model allows for learning. Learning can help understand
human behaviour, but can also result in better results for the learning party. Bayesian learning of reservation
values can be used to determine the zone of agreement for an issue based on the domain knowledge and bidding interactions.
Concluding for one-issue, learning positively influences bargaining quality, number of exchanged proposals,
and leads to a better compromise if both learn. Learning works always works better in the proposed case.

Subject(s)Analysing strengths and weakness of tactics
SummaryThis work uses an evolutionary approach to find on how agents using particular negotiation strategies fare against each
other in a negotiation. A standard bileteral multi-lateral negotiation model is used. The issues are continious
between a given range. Three types of techniques are considered: time-dependent, resource-
dependent, and behaviour dependent. The results give an nice overview on which tactic is effective against which
opponent. This is very interesting if the opponent is somehow able to determine the type of agent.

Cited-
Subject(s)ANAC, Pareto search, Bayes' rule
SummaryIAMhaggler first determines the discount factor of the opponent by using non-linear regression. Next, the found curve
is discounted to find the opponent bid curve. Next, the maximum is found on the opponent curve, and an
appropriate curve is plotted for the own utility curve. For domains without unordered issues Pareto-search is
used to determine all possible bids matching an utility. Next, it is determined which bid is the closest to the best
received opponent bid by using the euclidean distance. For domains with unordered issues, each
unorderded value is varied, after which the possible bids are determined which satisfy the utility. Finally, using Bayes'
rule for opponent modelling, the best possible bid for the opponent is chosen.

TitleLearning an Opponent's Preferences to Make Effective Multi-Issue Negotiation Trade-Offs
Author(s)R.M. Coehoorn, N.R. Jennings
Cited78
Subject(s)KDE Learning, Negotiation model, Concession based strategy
Summary Effective and efficient multi-issue negotiation requires an agent to have some indication of it's opponent's preferences
over the issues in the domain. Kernel Density Estimation (KDE) is used to estimate the weight attached to different issues
by different agents. It is assumed that if the value of an issue increases, that this is positive for one agent, and negative
for the other. No assumptions about relation between time, negotiation history and issue-weight are required, in contrast
to Bayesian learning. The difference between concessive (counter)offers is used to estimate the weights of the issues
(assumption: stronger concessions are made later on in the negotiation). Faratin's hill climbing algorithm augmented with KDE is
used to propose the next bid. KDE proved succesful on the used negotiation model. Future works entails testing the approach
against different opponent strategies and extending the approach to other negotiation models (see assumption in summary).

Cited5
Subject(s)Logic-like representation negotiation model, bin-based opponent model, one-issue continious
SummaryThe used method assumes that domain knowledge is available to partition the search space. Each turns, the agents communicate
the space where an agreement is possible. Each turn there is a negotiation between all agents to find a common space, which
means that the agent recommunicate a refined space of agreement until an agreement is reached. The proces continues until
a common decision is found (a decision is an element in the space of agreement). A learning algorithm can be used as follows:
first the full domain space is split into zones, which are allocated a uniform chance. This chance is updated for each region
for each agent based on the received space of agreement. When agents do not agree about the space, then a the space is chosen
which has the maximum support based on the chances of each space for each agent. This leads to a higher chance of agreement.

TitleThe Benefits of Opponent Models in Negotiation
Author(s)K. Hindriks, C.M. Jonker, D. Tykhonov
Cited-
Subject(s)Nice Mirroring Strategy using Bayesian Learning
SummaryOpponent models can aid in preventing exploitation, by determining the type of move of the opponent (selfish,
unfortunate, concession, nice, fortunate, silent), and by taking the opponents preferences into account to
increase the chance of acceptation. The mirror strategy mirrors the behaviours of the opponent, based on a
classification of the opponent move. Nice MS does the same, but adds a nice move, which is a move which only
increases the opponents utility without decreasing ours. Overall the strategy is shown to be effective by
comparing the result of first testing the strategy against a random agent, and then the other agents. Also, the
distance to a Kalai-Smorodinsky solution and the distance to the Nash Point is used as a metric. For
future work the exploitability of MS should be researched.

SummaryThe ANAC competition models bilateral multi-issue closed negotiations and provides a benchmark for negotiation agents.
Opponent models can also be used to identify the type of strategy of the opponent. Interesting agents for further analysis
are: IAM(crazy)Haggler, FSEGA (profile learning), and Agent Smith. Issues can be predicatable, which means that they
have a logical order, or unpredicatable, such as colors. This paper also includes acceptance conditions.
