Abstract

We describe the search for explicit general linear methods in Nordsieck form for which the stability function has only two nonzero roots. This search is based on state-of-the-art optimization software. Examples of methods found in this way are given for order p = 5, p = 6, and p = 7.

Keyword : general linear methods, Nordsieck methods, quadratic stability, least-squares minimization
