This paper presents such a demonstration for two problems, the n-bit adder with carry and even n-bit parity problems, and shows that development imposes, and benefits from, fewer constraints on evolutionary innovation than other approaches to scalability.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127289743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, the complexities involved in such designs make manual designs challenging and suggest the use of evolutionary design procedures. Yet, surprisingly, there has not been an attempt so far to evolve asynchronous sequential circuits. This paper pioneers this attempt and proposes an evolutionary approach for the first time. The evolution is done at two levels using a developmental approach called the developmental Cartesian genetic programming (DCGP) technique. The first level evolution aims at evolving race-free stable circuits, satisfying the input/output combinations, with no hazards or minimal number of hazards. The second level evolution modifies/adds more components to the circuits, in order to make them hazard-free, both with respect to static as well as dynamic hazards. Experimental results for a modulo-six counter and an ISCAS'89 benchmark circuit, 'lion', are provided as a proof of concept.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127243606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It features intensive applications of the Uniform Design Technique (UDT) to fitness function composing and crossover operator construction for the sake of multiple uniform search directions, better quality of offspring and higher computation efficiency. With an efficient and universal representation scheme based on standard component values and PSpice Net-list, it supports generation and optimization of circuit structures and component values. Moreover, its search efficiency is enhanced by an adaptation technique of genetic parameters, which pays attention to both population diversity, loci' effects and development of evolution. Both theoretic analyses and experimental results demonstrated its capability in finding out a set of Pareto-optimal solutions or effective design results via a shorter execution, and showed its potential in fully automated design of circuits concerning multi-objective requirements and preferences.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115488435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We survey a number of these concepts and discuss their intrinsic advantages as well as technical challenges relative to more traditional exploration modalities. Specifically, distributed sensors working in conjunction with traditional surface vehicles enable critical phenomena to be measured in previously inaccessible terrain over temporal and spatial scales not obtainable otherwise. We discuss how this strategy can be integrated into an overall science campaign and address several key issues in regards to returning the acquired data. Dispersion and data extraction studies performed for the global environmental micro sensors (GEMS) project will be presented in the context of Mars exploration and the search for life. The modeling results provide insight into optimum strategies for distributing probes and then extracting measured data either via an ad hoc network or direct exfiltration to an orbital asset.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115428860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our approach is to replace a single monolithic computing element with a system of simple, redundant, interconnected processing nodes such as a neural net. Each node will be a hardware device called a mote that can sense data, do simple processing and wirelessly transmit and receive data from its neighbors. The neural net is trained using an evolutionary algorithm called particle swarm optimization (PSO). This paper discusses the PSO algorithm, simulated results using the algorithm, and its application to the mote-based neural net. We also describe and show results for a new algorithm called dispersive PSO, which is useful when a neural net needs to be retrained to a different function or when a neural net needs to be retrained due to a node failure.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"22 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123726347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has been previously argued that because such components are human designed and intentionally have predictable responses, they may not be the most suitable medium to use when trying to get a naturally inspired search technique to solve a problem. Indeed allowing computer controlled evolution (CCE) to manipulate novel physical media can allow much greater scope for the discovery of unconventional solutions. Last year the authors demonstrated, for the first time, that CCE could manipulate liquid crystal to perform signal processing tasks (i.e frequency discrimination). In this paper we show that CCE can use liquid crystal to solve the much harder problem of controlling a robot in real time to navigate in an environment to reach an obstructed destination point.","PeriodicalId":448208,"journal":{"name":"2005 NASA/DoD Conference on Evolvable Hardware (EH'05)","volume":"88 23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114167468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
