Distributed Cognition As the Basis for Adaptation and Homeostasis In
DISTRIBUTEDCOGNITIONASTHEBASISFORADAPTATION ANDHOMEOSTASISINROBOTS james henry stovold Doctor of Philosophy University of York Computer Science July 2016 ABSTRACT Many researchers approach the problem of building autonomous systems by looking to biology for inspiration. This has given rise to a wide-range of artificial systems mimicking their biological counterparts—artificial neural networks, artificial endocrine systems, and artificial musculoskeletal systems are prime examples. While these systems are succinct and work well in isolation, they can become cumbersome and complicated when combined to perform more complex tasks. Autonomous behaviour is one such complex task. This thesis considers autonomy as the complex behaviour it is, and proposes a bottom-up approach to developing autonomous beha- viour from cognition. This consists of investigating how cognition can provide new approaches to the current limitations of swarm systems, and using this as the basis for one type of autonomous behaviour: artificial homeostasis. Distributed cognition, a form of emergent cognition, is most often described in terms of the immune system and social insects. By taking inspiration from distributed cognition, this thesis details the development of novel algorithms for cognitive decision-making and emergent identity in leaderless, homogenous swarms. Artificial homeostasis is provided to a robot through an architecture that combines the cognitive decision-making algorithm with a simple associative memory. This architecture is used to demonstrate how a simple architecture can endow a robot with the capacity to adapt to an unseen environment, and use that information to proactively seek out what it needs from the environment in order to maintain its internal state. iii CONTENTS Abstract iii Table of Contents v List of Figures viii List of Tables xi List of Code Listings xii Acknowledgements xiii Declaration xv 1 introduction 1 1.1 Motivation . -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Efficient and reliable power production is necessary to meet both the profitability of power systems operations and the electricity demand, taking also into account the environmental concerns about the emissions produced by fossil-fuelled power plants. The economic emission load dispatch problem has been defined and applied in order to deal with the optimization of these two conflicting objectives, that is, the minimization of both fuel cost and emission of generating units. This paper introduces and describes a solution to this famous problem using a new metaheuristic nature-inspired algorithm, called firefly algorithm, which was developed by Dr. Xin-She Yang at Cambridge University in 2007. A general formulation of this algorithm is presented together with an analytical mathematical modeling to solve this problem by a single equivalent objective function. The results are compared with those obtained by alternative techniques proposed by the literature in order to show that it is capable of yielding good optimal solutions with proper selection of control parameters. -

Recent Advances in Mathematics Firefly Algorithm Applied to Integer Programming Problems Nebojsa BACANIN, Ivona BRAJEVIC, Milan TUBA Faculty of Computer Science Megatrend University Belgrade Bulevar umetnosti 29, N. Belgrade SERBIA [email protected], [email protected], [email protected], Abstract: - Firefly algorithm is a recently added member of the swarm intelligence heuristics family. In this paper the firefly algorithm is adjusted and applied to integer programming problems. In order to deal with integer programming problems, firefly algorithm rounds the parameter values to the closest integer after producing new solutions. The performance of firefly algorithm is tested on seven problems widely used in the literature. Artificial bee colony algorithm is also implemented for comparison with the results of the firefly algorithm. Experimental results show that the firefly algorithm proved to be superior in almost all tested problems. Key-Words: - Firefly algorithm, Optimization metaheuristics, Integer programming, Swarm intelligence 1 Introduction Delaunay triangulation of the free configuration Linear programming optimization can find optimal space [3] are also solvable by integer programming solution to problems with hundreds of thousands of method.

Ronoh George Kamucha Tonny K. Omwansa School of Computing and Department of Electrical and School of Computing and Informatics Information Engineering Informatics University of Nairobi University of Nairobi University of Nairobi Nairobi, Kenya Nairobi, Kenya Nairobi, Kenya ABSTRACT 1GHz spectrum. TV white spaces (TVWS) can be used by Secondary Users Regulatory authorities worldwide have mandated the use of (SUs) through Dynamic Spectrum Access (DSA) as long as geo-location database (GLDB) for protection of incumbent they do not cause harmful interference to Primary Users users in TVWS network. GLDB is used by a SU or White (PUs). Due spectrum scarcity, there is increasing demand for Space Device (WSD) to find the set of frequency channels DSA. When there is a high density of SUs in a TVWS that can be used on a secondary basis at a given area and at network such as cellular access to TVWS, problem of any given time [5], [6], [7]. GLDB is populated through the interference among SUs will arise. Possibility of harmful use of a propagation model. The database contains estimated interference to PUs may also arise. Optimization of power power levels of PUs for any point in a particular region of allocation is therefore necessary to reduce the level of interest. The WSD, which has a Cognitive Radio System interference among SUs and to protect PUs against harmful (CRS), queries a central database. -
Migration and Conservation: Frameworks, Gaps, and Synergies in Science, Law, and Management
GAL.MERETSKY.DOC 5/31/2011 6:00 PM MIGRATION AND CONSERVATION: FRAMEWORKS, GAPS, AND SYNERGIES IN SCIENCE, LAW, AND MANAGEMENT BY VICKY J. MERETSKY,* JONATHAN W. ATWELL** & JEFFREY B. HYMAN*** Migratory animals provide unique spectacles of cultural, ecological, and economic importance. However, the process of migration is a source of risk for migratory species as human actions increasingly destroy and fragment habitat, create obstacles to migration, and increase mortality along the migration corridor. As a result, many migratory species are declining in numbers. In the United States, the Endangered Species Act provides some protection against extinction for such species, but no protection until numbers are severely reduced, and no guarantee of recovery to population levels associated with cultural, ecological, or economic significance. Although groups of species receive some protection from statutes such as the Migratory Bird Treaty Act and Marine Mammal Protection Act, there is no coordinated system for conservation of migratory species. In addition, information needed to protect migratory species is often lacking, limiting options for land and wildlife managers who seek to support these species. In this Article, we outline the existing scientific, legal, and management information and approaches to migratory species. Our objective is to assess present capacity to protect the species and the phenomenon of migration, and we argue that all three disciplines are necessary for effective conservation. We find significant capacity to support conservation in all three disciplines, but no organization around conservation of migration within any discipline or among the three disciplines. Areas of synergy exist among the disciplines but not as a result of any attempt for coordination. -
Swarm Intelligence for Multiobjective Optimization of Extraction Process
Swarm Intelligence for Multiobjective Optimization of Extraction Process T. Ganesan* Department of Chemical Engineering, Universiti Technologi Petronas, 31750 Tronoh, Perak, Malaysia *email: [email protected] I. Elamvazuthi Department of Electrical & Electronics Engineering, Universiti Technologi Petronas, 31750 Tronoh, Perak, Malaysia P. Vasant Department of Fundamental & Applied Sciences, Universiti Technologi Petronas, 31750 Tronoh, Perak, Malaysia ABSTRACT Multi objective (MO) optimization is an emerging field which is increasingly being implemented in many industries globally. In this work, the MO optimization of the extraction process of bioactive compounds from the Gardenia Jasminoides Ellis fruit was solved. Three swarm-based algorithms have been applied in conjunction with normal-boundary intersection (NBI) method to solve this MO problem. The gravitational search algorithm (GSA) and the particle swarm optimization (PSO) technique were implemented in this work. In addition, a novel Hopfield-enhanced particle swarm optimization was developed and applied to the extraction problem. By measuring the levels of dominance, the optimality of the approximate Pareto frontiers produced by all the algorithms were gauged and compared. Besides, by measuring the levels of convergence of the frontier, some understanding regarding the structure of the objective space in terms of its relation to the level of frontier dominance is uncovered. Detail comparative studies were conducted on all the algorithms employed and developed in this work. -
