Abstract:

As part of a continuing program of numerical tests of convergence accelerators, we have compared the iterated Aitken’s ${\Delta ^2}$ method, Wynn’s $\varepsilon$ algorithm, Brezinski’s $\theta$ algorithm, and Levin’s u transform on a broad range of test problems: linearly convergence alternating, monotone, and irregular-sign series, logarithmically convergent series, power method and Bernoulli method sequences, alternating and monotone asymptotic series, and some perturbation series arising in applications. In each category either the $\varepsilon$ algorithm or the u transform gives the best results of the four methods tested. In some cases differences among methods are slight, and in others they are quite striking.
