In 1959 Milne and Reynolds described a technique of stabilizing averages for damping out the increasingly disruptive oscillations of the error associated with certain multistep methods for solving ordinary differential equations numerically. In 1965 Timlake published a constructive proof of the fact that stabilizing averages exist for all conditionally stable multistep methods and in particular, he proved the existence of stabilizing averages for Milnes method which reduce by a factor of theetah superscript2k1 the disruptive component of the truncation error expression for any non-negative integer k. Numerical experiments were carried out to verify Timlakes theoretical results and the results are presented in this report. Author
