Book excerpt: Automatednegotiationis arguedto improvenegotiationoutcomes and reduce tra- action costs in electronic business and to enable sophisticated cooperation and - ordination between software agents in autonomous systems. However, due to the youth of the ?eld operative systems do not yet exist and scholars rely on simulation studies to evaluate potential system con?gurations for automated negotiation. We review the state of the art literature on simulation of automated negotiationalong its main components: the negotiation problem, the interaction protocol, and the so- ware agents. De?ciencies of existing approaches concerning the practical appli- tion in an open environment as the Internet, where automated negotiation proceeds fast, with different opponents, and for various negotiation problems, are identi?ed. To address these de?ciencies we model and simulate automated negotiation s- tems consisting of software agents and interaction protocols, which were proposed in negotiation and game theoretic mechansim design literature but not used in s- ulations yet. The proposed software agents follow generic offer generation and c- cession strategies and are governed by interaction protocols that allow agents to interrupt their strategy to avoid exploitation and unfavorable agreements. The - put for these automated negotiation systems are preferences elicited from human in negotiation experiments to guarantee realistically complex and diverse negot- tion problems. Simulation outcomes are compared across the different systems and to the results of the negotiation experiments along various outcome dimensions – proportion of (Pareto-optimal) agreements, dyadic and individual performance, and fairness.

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.

Book excerpt: Complex Automated Negotiations have been widely studied and are becoming an important, 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. These factors include the number of issues, dependency between issues, representation of utility, negotiation protocol, negotiation form (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 adequate bargaining strategies. 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. To realize such a complex automated negotiation, we have to incorporate advanced Artificial Intelligence technologies includes search, CSP, graphical utility models, Bays nets, auctions, utility graphs, predicting and learning methods. Applications could include e-commerce tools, decision-making support tools, negotiation support tools, collaboration tools, etc. In this book, we solicit papers on all aspects of such complex automated negotiations in the field of Autonomous Agents and Multi-Agent Systems. In addition, this book includes papers on the ANAC 2010 (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 one of real testbeds in which strategies for automated negotiating agents are evaluated in a tournament style.

Available in PDF, EPUB and Kindle. Book excerpt: "Automated negotiation is treated as multi-disciplinary area of rigorous research consisting of Multi Agent Systems (MAS) such as optimization, decision support system, game theory and e-commerce. Thus, automated negotiations can be treated as a search space problem where different autonomous agents try to occupy their own utilities via finding the best possible option obtained from the search space. In this work, a comprehensive study was conducted on the negotiations' elements in order to model Agent Z. Cultural algorithms were used in the modeling as they offer a dual inheritance system between the belief space and population space. Agent Z was modeled to be compatible with General Environment for Negotiation with Intelligent multi-purpose Usage Simulator (GENIUS). Moreover, the simulator allows agent Z to negotiate with a human negotiator through a user interface window. Agent Z has three major improvements through its versions (V1.0, V2.0, and V3.0). In Agent Z-V1.0, the agent was modeled to deal with cooperating opponents. In this version, the population size was fixed and independent on the domain size. Moreover, the termination operator was time and utility dependent. In Agent Z-V2.0 the number of children was changed to a percentage of the domain size instead of a fixed number in version 1. Additionally, a memory was added to the agent to store best offers sent from the opponents. An important modification in V2.0 was the algorithm of producing the child generation from several parents unlike V1.0, which was produced from two parents only. An internal clock was added to V2.0 that divided the time into two phases. Lastly Agent Z-V3.0 was a hybrid agent that integrated V1.0 and V2.0 and a C factor was introduced. Agent Z is much more cooperative than other agents and tends to find win-win agreement rather than win a negotiation. It has been observed that when negotiators cooperate the time to reach an agreement is faster than competing agents. Finally Agent Z was found to perform well with time and utility dependent agents unlike utility only dependent agents who were forced to accept the best offer sent when time is about to finish."--Abstract.

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.

Download or read book Negotiation and Argumentation in Multi Agent Systems written by Fernando Lopes and published by Bentham Science Publishers. This book was released on 2014-04-08 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agent technology has generated lots of excitement in the past decade. Currently, multi-agent systems (MAS) composed of autonomous agents representing individuals or organizations and capable of reaching mutually beneficial agreements through negotiation and argumentation are becoming increasingly important and pervasive. Research on both automated negotiation and argumentation in MAS has a vigorous, exciting tradition. However, efforts to integrate both areas have received only selective attention in the academia and the practitioner literature. A symbiotic relationship could significantly strengthen each area’s progress and trigger new R&D challenges and prospects toward the advancement of automated negotiators and argumentation tools. Negotiation and Argumentation in Multi-Agent Systems presents the current state-of-the-art on the theory and practice of automated negotiation and argumentation in MAS. The eBook encourages the interaction between these two areas in data modelling and attempts to converge them toward mutual enhancement and synergism. Equally, the monograph brings together researchers and industry practitioners specialized in these areas to share R&D results and discuss existing and emerging theoretical and applied problems. This book is intended as a textbook for graduate courses and a reference book for researchers, advanced-level students in Computers Science, and IT practitioners.

Download or read book Automated Negotiation for Complex Multi agent Resource Allocation written by Bo An and published by . This book was released on 2011 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The problem of constructing and analyzing systems of intelligent, autonomous agents is becoming more and more important. These agents may include people, physical robots, virtual humans, software programs acting on behalf of human beings, or sensors. In a large class of multi-agent scenarios, agents may have different capabilities, preferences, objectives, and constraints. Therefore, efficient allocation of resources among multiple agents is often difficult to achieve. Automated negotiation (bargaining) is the most widely used approach for multi-agent resource allocation and it has received increasing attention in the recent years. However, information uncertainty, existence of multiple contracting partners and competitors, agents' incentive to maximize individual utilities, and market dynamics make it difficult to calculate agents' rational equilibrium negotiation strategies and develop successful negotiation agents behaving well in practice. To this end, this thesis is concerned with analyzing agents' rational behavior and developing negotiation strategies for a range of complex negotiation contexts. First, we consider the problem of finding agents' rational strategies in bargaining with incomplete information. We focus on the principal alternating-offers finite horizon bargaining protocol with one-sided uncertainty regarding agents' reserve prices. We provide an algorithm based on the combination of game theoretic analysis and search techniques which finds agents' equilibrium in pure strategies when they exist. Our approach is sound, complete and, in principle, can be applied to other uncertainty settings. Simulation results show that there is at least one pure strategy sequential equilibrium in 99.7% of various scenarios. In addition, agents with equilibrium strategies achieved higher utilities than agents with heuristic strategies. Next, we extend the alternating-offers protocol to handle concurrent negotiations in which each agent has multiple trading opportunities and faces market competition. We provide an algorithm based on backward induction to compute the subgame perfect equilibrium of concurrent negotiation. We observe that agents' bargaining power are affected by the proposing ordering and market competition and for a large subset of the space of the parameters, agents' equilibrium strategies depend on the values of a small number of parameters. We also extend our algorithm to find a pure strategy sequential equilibrium in concurrent negotiations where there is one-sided uncertainty regarding the reserve price of one agent. Third, we present the design and implementation of agents that concurrently negotiate with other entities for acquiring multiple resources. Negotiation agents are designed to adjust 1) the number of tentative agreements and 2) the amount of concession they are willing to make in response to changing market conditions and negotiation situations. In our approach, agents utilize a time-dependent negotiation strategy in which the reserve price of each resource is dynamically determined by 1) the likelihood that negotiation will not be successfully completed, 2) the expected agreement price of the resource, and 3) the expected number of final agreements. The negotiation deadline of each resource is determined by its relative scarcity. Since agents are permitted to decommit from agreements, a buyer may make more than one tentative agreement for each resource and the maximum number of tentative agreements is constrained by the market situation. Experimental results show that our negotiation strategy achieved significantly higher utilities than simpler strategies. Finally, we consider the problem of allocating networked resources in dynamic environment, such as cloud computing platforms, where providers strategically price resources to maximize their utility. While numerous auction-based approaches have been proposed in the literature, our work explores an alternative approach where providers and consumers negotiate resource leasing contracts. We propose a distributed negotiation mechanism where agents negotiate over both a contract price and a decommitment penalty, which allows agents to decommit from contracts at a cost. We compare our approach experimentally, using representative scenarios and workloads, to both combinatorial auctions and the fixed-price model, and show that the negotiation model achieves a higher social welfare.
