The underlying theory of vector sequence extrapolation methods for linear and nonlinear problems is examined. It is shown that nonlinearity limits savings in total number of iterations to 50% for strongly nonlinear problems when linear-based extrapol

The temporal evolution of small and large ensembles is examined for the Lorenz equations. It is shown that a general closed system of ensemble averaged equations can be developed for the Lorenz equations, independent of the size of the ensemble. The
