Abstract

First a review of previous results on dependence graphs and roundoff error analyses is presented. Then it is shown that allowing perturbations of outputs does not change the bounds on the forward error essentially in two important cases. A new condition number of the algorithm is introduced. Finally, a classification of all numerical algorithms is given.
