An architecture for evolving robust shared communication systems

Abstract. Genetic algorithms are adaptive search techniques which have been used to learn high-performance knowledge structures in reactive environments that pro-vide information in the form of payoff. In general, payoff can be viewed as a noisy function of the structure being evaluated

. An important task for a mobile robot is to determine its location in the environment. This task is called positioning. In this paper we represent two algorithm for positioning in a noisy environment. The first one is for special use in simulation soccerserver [1] environment, while the second

protocol. The main idea is to use binary codes to correct bit errors occurring during the fast bit exchanges. Our protocol is perfectly suitable to be employed in noisy wireless environments such as RFID.

To prevent or alleviate conflicts in multi-agent environ-ments, it is important to distinguish between situations where another agent has misbehaved intentionally and situations where the misbehavior was accidental. One situation where this problem arises is the Noisy Iterated Prisoner’s Dilemma, a

Determining the solution space for a coordinated whole body movement in a noisy environment: application to the upstart in gymnastics This item was submitted to Loughborough University's Institutional Repository by the/an author.

This paper reports on one aspect of the Acoustic Ecology project of the UBC Institute for Hearing Accessibility Research. We examined the effect of a noisy environment on speech communication, with the aim of testing our

This paper studies the problem of recovering a signal with a sparse representation in a given orthonormal basis using as few noisy observations as possible. As opposed to previous studies, this paper models observations which are subject to the type of ‘clutter noise ’ encountered in radar

We investigate the emergent behavior of four types of generic dynamical systems under random environmental perturbations. Sufficient conditions for nearly-emergence in various scenarios are presented. Recent fundamental works of F. Cucker and S. Smale on the construction and analysis of flocking models directly inspired our present work. Keywords: emergence; Cucker-Smale model; dynamical system; flocking; multiagent system; consensus problems; random noise; linguistic evolution.
