For example, power companies have to agree on how to use the power grid, and airlines have to agree on how to schedule takeoffs and landings. Mechanisms for social choice are called incentive-compatible when cooperative behavior is optimal for all parties. The most well-known examples of incentive-compatible mechanisms are auctions. However, the party that receives the auction revenue has an incentive to manipulate the outcome to increase the revenue. For example, a power grid operator has an interest to reduce capacity and drive up prices. Conversely, if it provides sufficient capacity to every user it derives no revenue to cover its costs. We present a mechanism for social choice that is incentive-compatible without generating a payment surplus. We give several examples of applications where it solves the social choice problem without unwanted incentives, and provides significantly better overall utility than any other known mechanism.","PeriodicalId":281008,"journal":{"name":"Proceedings.

We look at the problem of scheduling multiple meetings between various groups of agents that arise over time. Each of the agents has private information regarding their tune preferences for meetings. Our aim is to extract this information and assign the meetings to times in a way that maximises social welfare. We discuss problems with previous attempts to design incentive compatible (IC) and individually rational (IR) mechanisms for the task. We focus on the problem of determining when agents are available. In particular, we show that when agents with general valuation functions are asked to supply their availability for meeting times, there is no IC and IR mechanism. Given this impossibility result, we show how the likelihood of violating IR can be reduced through agents expressing their value for the presence of others at meetings. We also show how requesting agent preferences for entire schedules helps to eliminate IC problems.","PeriodicalId":281008,"journal":{"name":"Proceedings.

We conduct our experiments on RoboNBA, which is a multi-agent system testbed. Local behaviors and global performance in RoboNBA are introduced. In addition, we address the problem of how to quantitatively measure the global performance in RoboNBA. Through experiments and analysis, we try to examine how agents' local behaviors can lead to interesting global performance of a match (e.g., optimized match results) in three problems: (1) cooperation between agents; (2) rational decision making; (3) coordination among agents.","PeriodicalId":281008,"journal":{"name":"Proceedings.

Over the last four years, the author has been working on the design of a distributed sensor network for vehicle tracking using adaptive radar sensors. This effort has reignited his long-term interest in the use of organizational structuring for handling scaling issues in multiagent systems. In This work, he first examines how organizational structuring was used in their design to reduce the computational and communication load involved in coordinating agent activities, and he discusses experiments that indicate the complex set of issues that need to be considered in evaluating the effectiveness of different organizational variants. He also briefly illustrates how it is possible to model the performance of these variants analytically, and predicts their performance. He then presents bottom-up techniques, based on negotiation, for organizational instantiation and adaptation in a dynamic environment. Finally, he discusses some work on a knowledge-based top-down approach for organizational design.","PeriodicalId":281008,"journal":{"name":"Proceedings.

An interesting research problem in a team-based game is the role assignment problem (RAP). The problem requires agents to decide their respective roles based on real-time feedback from a dynamically changing environment. The minority game (MG), as used in modeling financial marketing problems, has shown similar characteristics that meet the fundamental requirements of RAP. We propose a formulation of MG strategies for studying RAP in a specific team-based game: RoboCup simulation league (RSL). Through experimentation, we demonstrate that MG strategies improve the effectiveness of role assignment among agents. The improvement validates some characteristics, e.g., the phase transition phenomenon on the memory size, as discovered in the theoretical MG model.","PeriodicalId":281008,"journal":{"name":"Proceedings.

Tentative stereotype models allow for good predictions of a modeled agent's behavior even after few observations. Periodic revaluation of the chosen stereotype and the potential for switching between different stereotypes or to the observation based model aids in dealing with very similar (but not identical) stereotypes and agents that do not conform to any stereotype. Finally, compactification of observations keeps the application of the model efficient by reducing comparisons within the nearest neighbor rule. Our experiments show that stereotyping significantly improves cases where using just the original method performs badly and that revaluation and switching fortify stereotyping against the potential risk of using an incorrect stereotype. Compactification shows good potential for improving efficiency, but is sometimes at risk of losing important observations.","PeriodicalId":281008,"journal":{"name":"Proceedings.

It incorporates fuzziness and online analytical processing (OLAP) based mining to effectively process the information reported by agents. First, we describe a fuzzy data cube OLAP architecture to facilitate effective storage and processing of the state information reported by agents. This way, the action of the other agent, even not in the visual environment of the agent under consideration, can simply be predicted by extracting online association rules from the constructed data cube. Second, we present a new action selection model, also based on association rules mining. Finally, we generalize not sufficiently experienced states, by mining multi-level association rules from the proposed fuzzy data cube. Experimental results obtained on a well-known pursuit domain show the robustness and effectiveness of the proposed approach.","PeriodicalId":281008,"journal":{"name":"Proceedings.
