Available in PDF, EPUB and Kindle. Book excerpt: Automated bilateral negotiation forms an important type of interaction in agent based systems for electronic commerce; it allows seller and customer to determine the terms and content of the trade iteratively and bilaterally. Consequently, deals may be highly customized (especially for complex goods or services) and highly adaptable to changing circumstances. Moreover, by automating the negotiation process, the potentially time-consuming process is delegated to autonomous software agents who conduct the actual negotiation on behalf of their owners. In this paper, we consider the problem of a seller agent negotiating bilaterally with a customer about selecting a subset from a collection of goods or services, viz. the bundle, together with a price for that bundle. The techniques developed in this paper try to benefit from the so-called win-win opportunities, by finding mutually beneficial alternative bundles during negotiations. To facilitate the search for win-win opportunities the developed techniques rely on a continuously updated model of the opponent's preferences. Several papers on multiagent negotiation have already focused on finding win-win opportunities through opponent modeling. However, these papers only consider preference relations for which the issues have independent valuations. In this paper we study the considerably harder problem of interdependencies between issues. In order to model such complex interdependencies between items, we introduce the novel concept of utility graphs. Utility graphs build on the idea that highly nonlinear utility functions, which are not decomposable in sub-utilities of individual items (such as in the seminal work of Raiffa), may be decomposable in sub-utilities of clusters of inter-related items. They mirror, to a certain extent, the graphical models developed in (Bayesian) inference theory. The idea, behind using utility graphs in a one multi-issue bargaining setting, is to provide the seller with a formalism for exploring the exponentially large bundle space, efficiently. In this paper, we show how utility graphs can be used to model an opponent's (i.e. customer's) preferences. Moreover, we also propose an updating procedure to obtain approximations of the customer s utility graph indirectly, by only observing his counter-offers during the negotiation. At the start of a negotiation process, the seller's approximation of the customer's utility graph represents some prior information about the maximal structure of the utility space to be explored. This prior information could be obtained through a history of past negotiations or the input of domain experts. (An important advantage of utility graphs is that they can handle both qualitative and quantitative prior information.) After every (counter) offer of the customer, this approximation is refined. Conducted computer experiments show that by using only a fairly weak assumption on the maximal structure of customers utility functions the updating procedure enables the seller to suggest offers that closely approximate Pareto efficiency. By using utility graphs, Pareto-efficiency can be reached with few negotiation steps, because we explicitly model the underlying graphical structure of complex utility functions of the Buyer and use it to explore the outcome space. Consequently, our approach is applicable to time constrained negotiations, or negotiations where the impatience of one of the parties is a limiting factor. Furthermore, unlike other solutions for high-dimensional negotiations, the proposed approach does not require a mediator.

This book was released on 2012-09-13 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Complex Automated Negotiations are a widely studied, emerging area in the field of Autonomous Agents and Multi-Agent Systems. In general, automated negotiations can be complex, since there are a lot of factors that characterize such negotiations. For this book, we solicited papers on all aspects of such complex automated negotiations, which are studied in the field of Autonomous Agents and Multi-Agent Systems. This book includes two parts, which are Part I: Agent-based Complex Automated Negotiations and Part II: Automated Negotiation Agents Competition. Each chapter in Part I is an extended version of ACAN 2011 papers after peer reviews by three PC members. Part II includes ANAC 2011 (The Second Automated Negotiating Agents Competition), in which automated agents who have different negotiation strategies and implemented by different developers are automatically negotiate in the several negotiation domains. ANAC is an international competition in which automated negotiation strategies, submitted by a number of universities and research institutes across the world, are evaluated in a tournament style. The purpose of the competition is to steer the research in the area of bilateral multi-issue, closed negotiation. This book includes rules, results, agents and domains descriptions for ANAC2011 submitted by organizers and finalists.

Available in PDF, EPUB and Kindle. Book excerpt: Complex Automated Negotiations represent an important, emerging area in the field of Autonomous Agents and Multi-Agent Systems. Automated negotiations can be complex, since there are a lot of factors that characterize such negotiations. These factors include the number of issues, dependencies between these issues, representation of utilities, the negotiation protocol, the number of parties in the negotiation (bilateral or multi-party), time constraints, etc. Software agents can support automation or simulation of such complex negotiations on the behalf of their owners, and can provide them with efficient bargaining strategies. To realize such a complex automated negotiation, we have to incorporate advanced Artificial Intelligence technologies includes search, CSP, graphical utility models, Bayes nets, auctions, utility graphs, predicting and learning methods. Applications could include e-commerce tools, decision-making support tools, negotiation support tools, collaboration tools, etc. This book aims to provide a description of the new trends in Agent-based, Complex Automated Negotiation, based on the papers from leading researchers. Moreover, it gives an overview of the latest scientific efforts in this field, such as the platform and strategies of automated negotiating techniques.

Download or read book Exploring the Strategy Space of Negotiating Agents written by Tim Baarslag and published by Springer. This book was released on 2016-01-21 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reports on an outstanding thesis that has significantly advanced the state-of-the-art in the area of automated negotiation. It gives new practical and theoretical insights into the design and evaluation of automated negotiators. It describes an innovative negotiating agent framework that enables systematic exploration of the space of possible negotiation strategies by recombining different agent components. Using this framework, new and effective ways are formulated for an agent to learn, bid, and accept during a negotiation. The findings have been evaluated in four annual instantiations of the International Automated Negotiating Agents Competition (ANAC), the results of which are also outlined here. The book also describes several methodologies for evaluating and comparing negotiation strategies and components, with a special emphasis on performance and accuracy measures.

In many multi-issue bargaining settings, negotiation becomes more than a zero-sum game, so bargaining agents have an incentive to cooperate in order to achieve efficient win-win agreements. Also, in a complex negotiation, there could be multiple issues that are interdependent. Thus, agent's utility will become more complex than simple utility functions. Further, negotiation forms and protocols could be different between bilateral situations and multi-party situations.

Book excerpt: Publication of the Handbook of Group Decision and Negotiation marks a milestone in the evolution of the group decision and negotiation (GDN) eld. On this occasion, editors Colin Eden and Marc Kilgour asked me to write a brief history of the eld to provide background and context for the volume. They said that I am in a good position to do so: Actively involved in creating the GDN Section and serving as its chair; founding and leading the GDN journal, Group Decision and Negotiation as editor-in-chief, and the book series, “Advances in Group Decision and Negotiation” as editor; and serving as general chair of the GDN annual meetings. I accepted their invitation to write a brief history. In 1989 what is now the Institute for Operations Research and the Management Sciences (INFORMS) established its Section on Group Decision and Negotiation. The journal Group Decision and Negotiation was founded in 1992, published by Springer in cooperation with INFORMS and the GDN Section. In 2003, as an ext- sion of the journal, the Springer book series, “Advances in Group Decision and Negotiation” was inaugurated.

Book excerpt: PRIMA 2008 was the 11th in a series of conferences gathering researchers - voted to developing intelligent agents and multi-agent technologies from Asia and the Paci?c regions. From its ?rst incarnation over a decade ago, PRIMA has emerged as a signi?cant international forum, facilitating the exchange and dissemination of innovative research from around the globe. PRIMA 2008 was held in Vietnam, a tribute to this country’s emerging s- enti?c vitality and importance as a developing innovation center. The Program Committee received 56 submissions from 20 countries. Many of these papers are the work of PhD or Masters students from Asian countries including - rea, Japan, Indonesia, Malaysia, Iran, India, and Vietnam. In accordance with the rules, each submission was carefully peer-reviewed by three Program C- mittee referees. Only 19 submissions were accepted as regular papers, with a competitive rate of 33%. Additionally, the Program Committee decided to accept 22 short papers mainly written by graduate students, allowing our young colleagues an opp- tunity to present their work and new perspectives. These fresh perspectives enhanced our experienced of the conference and complemented the high quality of the professional papers submitted.
