Abstract
This paper presents a survey of research results obtained by the authors and by their team, on the round-off error propagation and the accuracy of mathematical computations.
The efficiency of the Permutation-Perturbation method is shown:
-
i)
For evaluating the accuracy of the exact finite method results,
-
ii)
For breaking off the iterative processes using the optimum termination criterion and evaluating the accuracy of the results,
-
iii)
For choosing the optimum integration step in approximate methods, such as the finite difference method.
The Permutation-Perturbation method may be also used to evaluate the data error propagation.
Examples are presented to illustrate the efficiency of the method.
