Accelerating Convergence of Iterative Processes A technique is discussed which, when applied to an iterative procedure for the solution of an equation, accelerates the rate of convergence if the iteration converges and induces convergence if the iteration diverges. An illustrative example is given. CACM June, 1958 Wegstein, J. H. CA580602 JB March 22, 1978 9:09 PM 20 5 20 20 5 20 20 5 20
