We examine the case study of competition on the standardization of video cassette recorders (VCR). In this case the compatibility of the video software is definitely important to choose the VCR. The simulation result shows that the communications among agents are breaking the symmetry of the market share, then the asymmetry is enlarged further with accelerated speed. The model is useful to understand what has happened in the technological lock-in phenomena.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

This adaptation is constrained and not all forms of coordination are feasible. Since organizations are inherently computational entities insight is gained by examining adaptation in organizations of intelligent artificial agents. Using ORGAHEAD a series of virtual experiments were run. Results suggest that concurrent learning mechanisms generate the ability to learn meta-change strategies which can be either adaptive or maladaptive. Consequently both organizational performance and form depend on environmental change, agent and structural learning, and the emergence of institutionalized strategies.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

In our model, each agent works on genetic programming tasks, resides at a workstation on the Internet and is capable of coordinating its activities with a variable number of other agents using the same coordination protocol. The system of agents has a virtual topology that is structured as a loosely coupled network of domains, each of which contains some number of nodes in the overall system. Agents (nodes) cooperate via DGPP, a contract net based high level communication and control protocol. A testbed based on the model has been implemented in Java. Several standard problems were tested. The results showed near linear speed up using six Pentium Pro/Windows NT workstations.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

We have specifically been investigating the space of functions for evaluating alternative distributed task schedules for multi-operator applications. In this paper, we describe some candidate functions and converge on intuitively appealing functions, which we show to lead to equivalent preferences over distributed schedules. We then look at the computational complexity of finding schedules that (approximately) optimize this function. When context switching costs are thrown into the mix moreover, the complexity becomes even more daunting. To address these problems, this paper summarizes our work on forging correspondences between our problems and those studied in operations research. Moreover, we have developed a new hill-climbing strategy for solving these problems, and we show that it performs well within the range of parameter settings that are representative of our application domain.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.

We especially present: 1) how the MAS software design dimension enables to define appropriate tools levels for designing multi-agent systems; 2) how MAS knowledge abstraction adds significant value to implement a computational model of agents; 3) how MAS services dimension allows to correctly extend the GEAMAS environment by integrating new multi-agent concepts such as organization capacities or learning mechanisms.","PeriodicalId":244857,"journal":{"name":"Proceedings International Conference on Multi Agent Systems (Cat.
