Comparaçãoo entre Variantes do Método de Pontos Interiores para Multifluxo

In this paper we compare two specialized versions of the primal-dual interior point method for multiflow problems: one version called {\it Usual} and a second one known as {\it Predictor-Corrector}. We studied the cpu time, the number of iterations of the primal-dual method, as well as the total number of iterations of the preconditioned conjugate gradient in the presence of distinct starting points and different initializations in the preconditioned conjugate gradient.
