Previous work by others suggests that the amount of information available to the individuals plays a crucial role in group performance. This work extends the previous work to show that the control parameters in the decision rule utilized by the individuals significantly effects group behavior. This work shows that the decision rule influences the group behavior to a greater extent than the amount of information does. Indeed, a control scheme has been found that improves the performance of the system such that the behavior is no longer drastically affected by varying the amount of information available.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

We define a behavior-based system relying on automatic design process using artificial evolution to synthesize high level behaviors for autonomous agents. Behavioral strategies are described by tree-based structures, and manipulated by generic evolving processes. Each strategy is dynamically evaluated during simulation, and is weighted by an adaptation function as a quality factor that reflects its relevance as good solution for the learning task. It is computed using heterogeneous reinforcement techniques associating immediate reinforcements and delayed reinforcements as dynamic progress estimators.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

Asynchronous control protocols and a method for processing evidence are developed to ensure global consistency at all times.

We first give an overview of primates' social competences, then we draw a parallel between the main problems found in the study of primate societies (regarding their social organization) and some of the most commonly encountered issues when designing Multi-Agent Systems. We describe a model of social cognition and perception that we have experimented. Its results show that some social concepts can be implemented by attaching importance to the interactions between the agents, instead of using a complicated individual-based model. Finally, we discuss the main extensions we are working on and propose applications to Multi-Agent technology.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

The paper presents an approach to multi machine scheduling that follows the multiagent learning paradigm known from the field of distributed artificial intelligence. According to this approach the machines collectively and as a whole learn and iteratively refine appropriate schedules. The major characteristic of this approach is that learning is distributed over several machines, and that the individual machines carry out their learning activities in a parallel and asynchronous way.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

We validate the framework with experimental results using reinforcement learning agents in a market system, as well as by other experimental results gathered from the AI literature.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

Exploiting multiple agents for complex problems is promising, however, learning is necessary since complete domain knowledge is rarely available. The temporal difference algorithm is applied in each agent to learn a heuristic evaluation of states. Besides the reward for solutions produced by agents, we define the reward for coherence as a whole and exploit them to facilitate cooperation among agents for global problem solving. We evaluate the method by experiments on the satellite design problem. The result shows that our method enables agents to learn to cooperate as well as to learn individual heuristics within one framework. Especially, agents themselves learn to take the appropriate balance between exploration and exploitation in problem solving, which is known to greatly affect the performance. It also suggests the possibility of controlling the global behavior of multi agent systems via rewards in reinforcement learning.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

Two approaches are evaluated, corresponding to heterogeneous preferences and heterogeneous transaction costs; empirically, the transaction cost case provides stability with near optimal payoffs under certain conditions. Theoretically, in the idealized case of an infinite number of agents, it is proven that the system with added heterogeneous preferences has a fired point different from that of the unbiased system, guaranteeing suboptimal perfomance, while the transaction cast case is demonstrated to have a fixed point identical to that of the unbiased system, and it is further shown to be a contraction mapping, guaranteeing convergence. This contraction mapping allows us to conceptualize the model with heterogeneous transaction costs as a decentralized root finding system.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.
