We have constructed an inequality for the stability control of the Dormand-Prince method of the eighth order of accuracy and a fi rst-order method with an enhanced stability region, based on the fi rst seven stages. There are given some numerical
results con fi rming the effi ciency increase due to alternating order using.
Keywords: stiff system, explicit methods, accuracy and stability control, algorithm of variable order and step.
