Eficiência probabilística de algoritmos numéricos

Ourique, Luiz Eduardo January 1990 (has links)
Seguindo as ideias de s. smale, estudamos a eficiencia probabilistica de algoritmos numericos para equacoes diferenciais ordinarias. especial atencao e dada a dois exemplos classicos: os algoritmos de runge-kutta de dois e de quatro estagios, sendo a sua eficiencia estimada em termos de medidas gaussianas. em ambos os casos, sao obtidas estimativas detalhadas que levam a uma expressao para a media do erro global. / Following the ideas of S. Smale, we study the probabilistic efficiency of numerical algorithms in ordinary differential equations. Special attention is directed to two classical examples: the algorithms of Runge-Kutta of two and four stages with their efficiency estimated in terms of gaussian measures. In both these cases detailed estimates are given. leading to an expression for the mean global error.
