Semi-implicit numerical integration methods are an effective trade-off between weakly stable explicit and computationally expensive implicit ODE solvers. Variable stepsize is a proven technique to raise the effectiveness of ODE solvers in real applications. This paper considers the implementation of extrapolation semi-implicit methods with adaptive timestep for a two initial value problems, HIRES and Rössler systems. The performance of various adaptive extrapolation methods was compared by… CONTINUE READING
