General linear methods are a wide class of numerical methods for solving ordinary differential systems which includes many classical methods, such as for example Runge-Kutta or linear multistep methods. We describe the construction of explicit methods in Nordsieck form with the so-called quadratic stability (QS), i.e. methods with stability function of the form p(w, z) = w^(r-1) (w^2 - p1(z)w + p0(z)); where p1(z) and p0(z) are polynomials of z. After satisfying order conditions and criteria that guarantee quadratic form of its stability function, the remaining free parameters of the methods are used to maximize region of absolute stability. We discuss the error estimation formulas and step changing strategies for constructed methods. The results of numerical experiments with variable stepsize code are also presented. REFERENCES [1] M.
