Este trabalho descreve o problema de traçamento de raios, que é freq¨uente em Geofísica e introduz sua solução utilizando métodos quase-Newton. Na literatura em geral, problemas desse tipo eram sempre resolvidos utilizando o método de Newton. Aqui foram utilizados, além do método de Newton, os métodos quase- Newton: Broyden, Inverse Column Updating Method e Inverse q−Columns Updating Method. Uma análise comparativa do desempenho desses métodos é feita, traçando seus performance profiles usando como medidas o número de iterações e o tempo de execução.References
