What processes can explain how very large populations are able to converge on the use of a particular word or grammatical construction without global coordination? Answering this question helps to understand why new language constructs usually propagate along an S-shaped curve with a rather sudden transition towards global agreement. It also helps to analyze and design new technologies that sup...

We study novel aspects of multi-agent Q-learning in a model market in which two identical, competing \pricebots" strategically price a commodity. Two fundamentally diierent solutions are observed: an exact, stationary solution with zero Bellman error consisting of symmetric policies, and a non-stationary, broken-symmetry pseudo-solution, with small but non-zero Bellman error. This \pseudo-conve...

A team consisting of an unknown number of mobile agents, starting from different nodes of an unknown network, possibly at different times, have to meet at the same node. Agents are anonymous (identical), execute the same deterministic algorithm and move in synchronous rounds along links of the network. An initial configuration of agents is called gatherable if there exists a deterministic algor...

The difference between the speed of the actions of different processes is typically considered as an obstacle that makes the achievement of cooperative goals more difficult. In this work, we aim to highlight potential benefits of such asynchrony phenomena to tasks involving symmetry breaking. Specifically, in this paper, identical (except for their speeds) mobile agents are placed at arbitrary ...

Wave height as well as water depth at the breaking point are two basic parameters which are necessary for studying coastal processes. In this study, the application of soft computing-based methods such as artificial neural network (ANN), fuzzy inference system (FIS), adaptive neuro fuzzy inference system (ANFIS) and semi-empirical models for prediction of these parameters are investigated. Th...

The central challenge in particle physics is to explore the 1-TeV scale and elucidate the nature of electroweak symmetry breaking. A key element in this quest is the search for the Higgs boson, the agent of electroweak symmetry breaking in the standard electroweak theory. Uncovering the secrets of the Higgs sector is the focus of much present and future experimental research. The LEP 2 experime...

Implementation of MD which provides the mediation function of an interface is a key to TMN-based management of the non-Q3 interface NE. We have implemented MD which has the mediation function of the Q3 interface in a conventional agent to Proxy-Agent. We have also duplicated Proxy-Agent to improve the reliability of the network management system and have succeeded the performance improvement by...
