Runge–Kutta Pairs of Orders 6(5) with Coefficients Trained to Perform Best on Classical Orbits

Abstract: We consider a family of explicit Runge–Kutta pairs of orders six and five without any additional property (reduced truncation errors, Hamiltonian preservation, symplecticness, etc.). This family offers five parameters that someone chooses freely. Then, we train them in order for the presented method to furnish the best results on a couple of Kepler orbits, a certain interval and tolerance. Consequently, we observe an efficient performance on a wide range of orbital problems (i.e., Kepler for a variety of eccen… Show more

“…For the minimization of the positive value u$$ u $$, we used differential evolution algorithm 9 . We have already tried this approach and got some interesting results in producing pairs from the family of interest here for integrating orbits 10 . In this latter work, we trained the coefficients of a RK6(5) pair on a couple of Kepler orbits.…”

“…9 We have already tried this approach and got some interesting results in producing pairs from the family of interest here for integrating orbits. 10 In this latter work, we trained the coefficients of a RK6(5) pair on a couple of Kepler orbits. Then we observed very pleasant results over a set of Kepler orbits as well as on other known orbital problems.…”
