Orientador: Sandra Augusta SantosDissertação (mestrado profissional) - Universidade Estadual de Campinas, Instituto de Matemática Estatística e Computação CientíficaResumo: Neste trabalho estudamos alguns métodos iterativos para resolver o problema de minimização irrestrita de funções suaves, entre os quais o Método da Máxima Descida, o Método de Gradientes Conjugados Lineares e o Método de Gradientes Conjugados não Lineares. Neste último analisamos geometricamente, em problemas bidimensionais, a variabilidade dos resultados em decorrência do ponto inicial, da precisão requerida e da escolha dos parâmetros associados à busca linear. Também observamos que os escalares beta, responsáveis pela conjugação das direções geradas, coincidem quando ...
