Explicit, semi-symmetric, hybrid, six-step, eighth order methods for solving \(y''=f(x,y)\). (English) Zbl 1431.65096

Summary: A family of explicit, semi-symmetric, eighth-order, six-step methods for the numerical solution of \(y''=f(x,y)\) is studied. This family can be derived through interpolation techniques and only two function evaluations are spent per step. An interval of periodicity is possessed and the phase-lag is of high order. We conclude with numerical tests over a set of problems justifying our effort of dealing with the new methods.
