abstract = "The computational efficiency of existing genetic
programming (GP) software is improved through the
addition of parallelization and hybridization with a
low-level optimiser. The low-level optimiser is
implemented using genetic algorithm (GA), and two
different versions of the developed hybrid GP program
are presented. Timing and efficiency performance are
discussed, which includes a method of making the
original optimiser more than eight times faster.
Efficiency results indicate that through the use of the
optimiser, with sufficient variables included,
significantly fewer (about quarter to half) GP
generations are required to achieve working
metamaterial designs. Two low frequency, broadband
(225-450MHz) ground plane design examples, which are
25.3percent thinner than a previously published design
covering the same frequency band, are included.",
