Several explicit integration algorithms with self-adaptive time integration strategies are developed and investigated for efficiency and accuracy. These algorithms involve the Runge-Kutta second order, the lower Runge-Kutta method of orders one and two, and the exponential integration method. The al

โฆ Synopsis
A new algorithm is presented for accelerating the convergence of sequences possessing an asymptotic expansion. This method is compared to methods already shown. Explicit error estimates are given and the algorithm is shown to be nearly optimal. The algorithm is applied to the problem of numerical integration, and is shown to give good results for real analytic integrands.

For a diffusion type process dX, = d w + a(t, X) dt and a sequence (f,) of nonnegative functions necessary and sufficient conditions to the f, are established which guarantee the as. convergence of fn(X,) dt to zero.
