The Roundtable: An Abstract Model of Conversation Dynamics

Is it possible to abstract a formal mechanism originating schisms and governing the size evolution of social conversations? In this work we propose a constructive solution to this problem: an abstract model of a generic N-party turn-taking conversation. Th ...

Approximating geometric crossover in semantic space

Pawel Lichocki

We propose a crossover operator that works with genetic programming trees and is approximately geometric crossover in the semantic space. By defining semantic as program's evaluation profile with respect to a set of fitness cases and constraining to a spec ...

Evolution of stochastic switching rates in asymmetric fitness landscapes

Marcel Salathé

Uncertain environments pose a tremendous challenge to populations: The selective pressures imposed by the environment can change so rapidly that adaptation by mutation alone would be too slow. One solution to this problem is given by the phenomenon of stoc ...

A hybrid CMA-ES and HDE optimisation algorithm with application to solar energy potential

Jérôme Henri Kämpf, Darren Robinson

This paper describes the results of initial experiments to apply computational algorithms to explore a large parameter space containing many variables in the search for an optimal solution for the sustainable design of an urban development using a potentia ...

Evolutionary engineering design synthesis of on-board traffic monitoring sensors

Alcherio Martinoli

In this paper, a formal engineering design synthesis methodology based on evolutionary computation is presented, with special emphasis on the design and optimization of distributed independent systems. A case study concerned with design of a sensory system ...

Survey Propagation Inspired Algorithms for Satisfiability

Nicolas Macris, Shrinivas Kudekar

In this note we develop generalized Survey Propagation (SP) equations from the cavity method. We quantize the message space of the messages to develop a message passing rule. We investigate a framework of greedy algorithms for finding out satisfying assign ...

Uncovering the topology of configuration space networks

Paolo De Los Rios, David Gfeller, David Sébastien Morton de Lachapelle

The configuration space network (CSN) of a dynamical system is an effective approach to represent the ensemble of configurations sampled during a simulation and their dynamic connectivity. To elucidate the connection between the CSN topology and the underl ...

Application of dynamic subgrid-scale concepts from large-eddy simulation to modeling landscape evolution

Fernando Porté Agel

Landscapes share important similarities with turbulence: both systems exhibit scale invariance (self-similarity) over a wide range of scales, and their behavior can be described using comparable dynamic equations. In particular, modified versions of the Ka ...

A Dynamically Constrained Genetic Algorithm For Hardware-software Partitioning

Guillaume Zufferey, Pierre-André Mudry

In this article, we describe the application of an enhanced genetic algorithm to the problem of hardware-software codesign. Starting from a source code written in a high-level language our algorithm determines, using a dynamically-weighted fitness function ...

Evolution of Spiking Neural Circuits in Autonomous Mobile Robots

Dario Floreano, Jean-Christophe Zufferey, Claudio Mattiussi

We describe evolution of spiking neural architectures to control navigation of autonomous mobile robots. Experimental results with simple fitness functions indicate that evolution can rapidly generate spiking circuits capable of navigating in textured envi ...
