Evolving collective behaviours in simulated kilobots
(Association for Computing Machinery, 2018-04-09)The field of Evolutionary Robotics has multiple common tasks and widely used benchmark activities such as navigation, obstacle avoidance, and phototaxis. We present an evolutionary approach to learning behaviours that ... -
Evolving Racetrack Knowledge in a Racing Game.
(21st National Conference on Artificial Intelligence and Cognitive Science, 2010-07-30)This paper discusses the use of a Genetic Algorithm (GA) to evolve waypoint-based racing lines for computer-controlled cars in an online game. One goal is the reduction of developer effort, in order to automatically produce ... -
Examining the impact of neutrality on genetic algorithm population evolution
(SciTePress Digital Library, 2015-11-12)This paper examines the introduction of neutrality as proposed by Kimura (Kimura, 1968) into the genotype-phenotype mapping of a Genetic Algorithm (GA). The paper looks at the evolution of both a simple GA (SGA) and a ... -
Examining the use of a non-trivial fixed genotype-phenotype mapping in genetic algorithms to induce phenotypic variability over deceptive uncertain landscapes
(IEEE, 2011-06-05)In nature, living organisms can be viewed as the product of their genotype-phenotype mapping (GP-map). This paper presents a GP-map loosely based on the biological phe- nomena of transcription and translation, to create a ... -
Experimental Assessment of an Emotion Tracking Software Agent (ETA) for Assisting Communicative Interactions of Multitasking Users in Groupware
(Eurosis, 2011-08-22)Interactions such as discussion and negotiation in face-to-face work contexts strongly rely on non-verbal feedback. Such feedback provides indications of important negotiation states such as agreement or disagreement and ... -
Follow flee: A contingent mobility strategy for the spatial prisoner's dilemma
(Springer Verlag, 2016-08-10)This paper presents results from a series of experimental simulations comparing the performances of mobile strategies of agents participating in the Spatial Prisoner's Dilemma game. The contingent movement strategies Walk ... -
A Framework for Digital Wide-Area Survey from Aerial Photographs
(Wordwell Ltd., 1998)Despite the potential offered by modern computer technology to the labour-intensive work of 'Aerial Archaeology', few applications have been published. Where developments have been made, they have tended to be carried out ... -
A further analysis of the role of heterogeneity in coevolutionary spatial games
(Elsevier, 2017-11-04)Heterogeneity has been studied as one of the most common explanations of the puzzle of cooperation in social dilemmas. A large number of papers have been published discussing the effects of increasing heterogeneity in ... -
A genetic algorithm with a multi-layered genotype-phenotype mapping
(SciTePress Digital Library, 2010-08-24)In this paper we investigate the introduction of a multiple-layer genotype-phenotype mapping to a Genetic Algorithm (GA) which attempts to mimic more closely, the effects of nature. The motivation for introducing multiple-layers ... -
The Genetic Evolution of Kernels for Support Vector Machine Classifiers
(2004)Abstract. The Support Vector Machine (SVM) has emerged in recent years as a popular approach to the classi¿cation of data. One problem that faces the user of an SVM is how to choose a kernel and the speci¿c parameters for ... -
A groupware system for virtual product innovation management
(Wiley, 2007-10-11)We are experiencing a radical shift in the way organizations are designed, structured, and organized. New organizational forms such as virtual strategic partnerships and networks are replacing traditional bureaucratic, ... -
Identifying the reality gap between abstract and realistic models using evolved agents and simulated kilobots
(IEEE, 2018-12-12)A common challenge in evolutionary swarm robotics is the transfer of simulated results into real-world applications. This difficulty can arise in a variety of real-world settings and problems such as sensory differences in ... -
Improving spectral library search by redefining similarity measures
(Journal Of Chemical Information And Modeling, 2015-04-22)Similarity plays a central role in spectral library search. The goal of spectral library search is to identify those spectra in a reference library of known materials that most closely match an unknown query spectrum, on ... -
The influence of random interactions and decision heuristics on norm evolution in social networks
(Springer, 2011-05)In this paper we explore the effect that random social interactions have on the emergence and evolution of social norms in a simulated population of agents. In our model agents observe the behaviour of others and update ... -
Input and output data analysis for system dynamics modelling using the tidyverse libraries of R
(Wiley, 2018-09-07)From a number of perspectives, system dynamics is a data‐intensive activity. First, each modelling challenge addresses behaviour over time, where historical time series data inform the model‐building process, and techniques ... -
An introduction to system dynamics
(Cham: Springer, 2016-06-15)This chapter presents the important concepts underlying the system dynamics modeling method. Following an initial definition of the term model, a summary of a successful system dynamics intervention is described. The key ... -
A learning architecture for scheduling workflow applications in the cloud
(IEEE, 2011-09-15)The scheduling of workflow applications involves the mapping of individual workflow tasks to computational resources, based on a range of functional and non-functional quality of service requirements. Workflow applications ... -
A Machine Learning Application for Classification of Chemical Spectra
(2008)This paper presents a software package that allows chemists to analyze spectroscopy data using innovative machine learning (ML) techniques. The package, designed for use in conjunction with lab-based spectroscopic ...
