Para a otimização, implementamos duas versões modificadas do algoritmo de troca de Fedorov (1972), que é um método heurístico para encontrar delineamentos ótimos ou quase ótimos exatos. Apresentamos quatro exemplos para examinar a performance de delineamentos construídos com o novo critério composto, os exemplos 1, 3 e 4 visam o modelo de segunda ordem completo e o exemplo 2 visa o modelo de segunda ordem sem os efeitos quadráticos. Nos exemplos 1 e 3, para preservar bom desempenho em outras propriedades, a eficiência H não foi alta. Os resultados obtidos no exemplo 2 mostraram grande contribuição do uso da propriedade H no critério composto, produzindo delineamentos com alta eficiência nos demais quesitos. Em geral, o novo critério composto produziu delineamentos mais atrativos que os DP-ótimos de Gilmour & Trinca (2012), com valores de leverages mais homogêneos, e portanto mais robustos à perda de observações. Produziu também delineamentos com melhores propriedades do que os delineamentos construídos por subconjuntos em Ahmad & Gilmour (2010) / In this work we propose the use of a robustness measure to missing data to construct designs for factorial experiments. The robustness property is denoted the H criterion and it is added to a compound design criterion expression. Two versions of the modified exchange algorithm of Fedorov (1972) were implemented computationally for the search of exact optimum designs. Four examples are presented, examples 1, 3 and 4 consider the full second-order model and example 2 considers second-order model excluding the quadratic effects. The examples 1 and 3, in order to preserve good efficiency with respect to other properties, their H efficiency is not high. The results for example 2 showed good performance of the new compound criterion since it produced designs high by efficient for all other properties. In general, the new compound criterion produced more attractive designs than the DP criterion of Gilmour & Trinca (2012) since their leverages were more homogeneous and thus, the designs were more robust to missing data. The designs were also more attractive than those constructed by subsets as in Ahmad & Gilmour (2010)

Programação de horários usando um algoritmo genético especializado

Atala, Ali Veggi [UNESP] 27 February 2014 (has links) (PDF)
Made available in DSpace on 2014-12-02T11:16:57Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-02-27Bitstream added on 2014-12-02T11:20:50Z : No. of bitstreams: 1 000797336.pdf: 8867207 bytes, checksum: ee77fd35abfa82d47da021f7f3043be1 (MD5) / O problema de programação ótima de horários consiste em programar eventos aulas em um determinado número de salas, para um determinado número de alunos, com o objetivo de satisfazer certas condições de factibilidade. O problema é representado por um modelo de programação linear inteira mista e foi resolvido pela implementação de um algoritmo genético de Chu-Beasley, que apresenta as características de evitar a homogeinização da população, permitindo encontrar melhores soluções, modificado em três pontos fundamentais: (i) na geraçao da população inicial; (ii) na fase de melhoría local; (iii) no incremento da da diversidade. Adicionalmente, é apresentado um algoritmo construtivo na fase da geração da população inicial e na busca local, a fin de se permiter corrigir possíveis infactibilidades e melhorar a qualidade da população, tanto na fase inicial quanto na de melhoria local. O controle da diversidade e atualização da população são feitos obedecendo parâmetro que garante que o novo individuo tenha número de genes diferentes em relação aos demais individuos da população, evitando a homogeinização da mesma. O método proposto é aplicado no caso de testes da literatura especializada, e os dados do problema são os apresentados pela International Timebling Competition / The problem with optimum schedule programming consists of programming class-events for a given number of classrooms and students, with the goal of satisfying certain factibility conditions. The problem is represented by a full mixed linear programming model and has been solved by use of a genetic Chu-Beasley algorithm, that presents population homogenization avoidance features, allowing for best solutions, modified in three core points: (i) initial population generation; (ii) local improvement phase; (iii) diversity increase. Additionally, a constructive algorithm for the initial phase of initial population generation and local search is presented, this allows for correction of possible unsuitabilities and improves population quality, such in initial phase as in local improvements. Population diversity and updating control is done according to parameters that assure each new individual has a different genes number in relation to the other individuals of the population, avoiding homogenization. The proposed method is applied for test cases of specialized literature, and data for the tests are presented by International Timebling Competition
