Towards Adaptive programming Integrating Reinforcement Learning into a programming Language

引用

ACM SIGPLAN NOTICES 2008年第10期43卷 603-613页

作者： Simpkins, Christopher Bhat, Sooraj Isbell, Charles, Jr. Mateas, Michael Georgia Inst Technol Coll Comp Atlanta GA 30332 USA Univ Calif Santa Cruz Dept Comp Sci Santa Cruz CA 95064 USA

Current programming languages and software engineering paradigms are proving insufficient for building intelligent multi-agent systems-such as interactive games and narratives-where developers are called upon to write increasingly complex behavior for agents in dynamic environments. A promising solution is to build adaptive systems;that is, to develop software written specifically to adapt to its environment by changing its behavior in response to what it observes in the world. In this paper we describe a new programming language, An Adaptive Behavior Language (A(2)BL), that implements adaptive programming primitives to support partial programming, a paradigm in which a programmer need only specify the details of behavior known at code-writing time, leaving the run-time system to learn the rest. Partial programming enables programmers to more easily encode software agents that are difficult to write in existing languages that do not offer language-level support for adaptivity. We motivate the use of partial programming with an example agent coded in a cutting-edge, but non-adaptive agent programming language (ABL), and show how A(2)BL can encode the same agent much more naturally.

The asynchronous searching techniques are characterized by the fact that each agent instantiates its variables in a concurrent way. Then, it sends the values of its variables to other agents directly connected to it by using messages. These asynchronous techniques have different behaviors in the case of delays in sending messages. This article presents the opportunity for synchronizing the execution of agents in the case of asynchronous techniques. It investigates and compares the behaviors of several asynchronous techniques in two cases: agents process the received messages asynchronously (the real situation) and the synchronous case, when a synchronization of the execution of agents is done, i.e. the agents perform a computing cycle in which they process a message from a message queue. After that, the synchronization is done by waiting for the other agents to finalize the processing of their messages. The experiments show that the synchronization of the agents execution leads to lower costs in searching for solutions. A solution for synchronizing the agents execution is suggested for the analyzed asynchronous techniques.

IEEE Latin America Transactions 2008年第6期6卷 511-516页

作者： J. M. Gamboa M. J. Ramirez Departamento de mecatrónica y automatización Instituto Tecnológico de Estudios Superiores de Monterrey (ITESM) Campus Monterrey Monterrey Nuevo Leon Mexico

The main propose of this project is to design a multi-agent system platform on a flexible manufacturing cell (FMC). Taking into consideration all levels of functional issues, cellular architecture, standardization, and technical configurations, we take advantage of features released on a graphical programming commercial software, such as object oriented programming, distributed intelligence, and block function representation. The approach is addressed to encourage the usage of holonic and multiagent concepts in traditional manufacturing systems, with friendly software based upgrade and a minimum low cost hardware expansion. The intention is to develop a system that will fit into different levels of an enterprise, including shop-floor and manufacturing execution systems, and simultaneously we will deal with technological migration from conventional manufacturing structure to a holonic-ready FMC.

In repeated games with incomplete information, rational agents must carefully weigh the tradeoffs of advantageously exploiting their information to achieve a short-term gain versus carefully concealing their information so as not to give up a long-term informed advantage. The theory of infinitely-repeated two-player zero-sum games with incomplete information has been carefully studied, beginning with the seminal work of Aumann and Maschler. While this theoretical work has produced a characterization of optimal strategies, algorithms for solving for optimal strategies have not yet been studied. For the case where one player is informed about the true state of the world and the other player is uninformed, we provide a non-convex mathematical programming formulation for computing the value of the game, as well as optimal strategies for the informed player. We then describe an efficient algorithm for solving this difficult optimization problem to within arbitrary accuracy. We also discuss how to efficiently compute optimal strategies for the uninformed player using the output of our algorithm.

Application of multi-agents to power distribution systems

Application of multi-agents to power distribution systems

引用

作者： Nareshkumar, Koushaly West Virginia University

学位级别：M.S.

The electric power system has become a very complicated network at present because of re-structuring and the penetration of distributed energy resources. In addition, due to increasing demand for power, issues such as transmission congestion have made the power system stressed. A single fault can lead to massive cascading effects, affecting the power supply and power quality. An overall solution for these issues can be obtained by a new artificial intelligent mechanism called the multi-agent system. A multi-agent system is a collection of agents, which senses the environmental changes and acts diligently on the environment in order to achieve its objectives. Due to the increasing speed and decreasing cost in communication and computation of complex matrices, multi-agent system promise to be a viable solution for today’s intrinsic network problems. A multi-agent system model for fault detection and reconfiguration is presented in this thesis. These models are developed based on graph theory and mathematical programming. A mathematical model is developed to specify the objective function and the constraints. The multi-agent models are simulated in Java agent Development Framework and Matlab® and are applied to the power system model designed in the commercial software, Distributed Engineering Workstation© . The circuit that is used to model the power distribution system is the Circuit of the Future, developed by Southern California Edison. The multi-agent system model can precisely detect the fault location and according to the type of fault, it reconfigures the system to supply as much load as possible by satisfying the power balance and line capacity constraints. The model is also capable of handling the assignment of load priorities. All possible fault cases were tested and a few critical test scenarios are presented in this thesis. The results obtained were promising and were as expected.

Modelling and simulation of social systems with INGENIAS

引用

International Journal of agent-Oriented Software Engineering 2008年第2期2卷 196-221页

作者： Pavón, Juan Sansores, Candelaria Gómez-Sanz, Jorge J. Dep. Ingeniería del Software e Inteligencia Artificial Universidad Complutense de Madrid Profesor José García Santesmases s/n 28040 Madrid Spain

Most agent-based simulation toolkits are based on the Java programming language. This makes their use difficult for social scientists, who are usually not skilled in computer programming. However, agent modelling concepts are not unlike those which could be used for the modelling of social systems. This assumption is considered in proposing the use of a graphical agent-oriented language for the specification of social simulation models, and for transforming (automatically) these models to code for an agent-based simulation toolkit. In this manner, a social scientist could prepare social models in a more convenient way, and execute simulations on existing simulation toolkits, getting results back in terms of the model. This framework is built with a set of agent development tools, specifically, the INGENIAS Development Kit (IDK), which provides a customisable model editor and modules for automatic code generation.
