Über einige Methoden der Relaxationsrechnung

- 1952
After a study of the gradient method it is shown that relaxation methods are not necessarily successive approximations taking an infinite number of steps but that it is possible to speed up convergence such that the desired result is reached in a finite number of Steps.

On a successive transformation of probability distribution and its application to the analysis of the optimum gradient method
- Computer Science, Mathematics

The conjecture which was stated by Forsythe and Motzkin and was used as the logical basis of an acceleration procedure for the optimum gradient method is proved and it is said that when the matrix is ill-conditioned the convergence rate tends near to its worst possible value.
