Conclusions.
•HOSVS methods provide a useful method of combining the
efficiency gains of both higher
order and variable stepsize methods.
•
•The CEOT method is the most efficient where 6th-8th order integrators, which accurately calculate the re-parameterisation function,
are required.
•
•The OEC method is useful for very high order integrators
or where existing coefficients
are to be used, which accurately calculate the re-parameterisation function.
•
•The MO method is best suited, and the most efficient,
where accurate determination of
the re-parameterisation function is not important, such as time
transformations based on the
eccentricity of the orbit of Mercury.
