abstract = "Whereas the current practise of designing antennas by
hand is severely limited because it is both time and
labour intensive and requires a significant amount of
domain knowledge, evolutionary algorithms can be used
to search the design space and automatically find novel
antenna designs that are more effective than would
otherwise be developed. Here we present our work in
using evolutionary algorithms to automatically design
an X-band antenna for NASA's Space Technology 5 (ST5)
spacecraft. Two evolutionary algorithms were used: the
first uses a vector of real-valued parameters and the
second uses a tree-structured generative representation
for constructing the antenna. The highest-performance
antennas from both algorithms were fabricated and
tested and both outperformed a hand-designed antenna
produced by the antenna contractor for the mission.
Subsequent changes to the spacecraft orbit resulted in
a change in requirements for the spacecraft antenna. By
adjusting our fitness function we were able to rapidly
evolve a new set of antennas for this mission in less
than a month. One of these new antenna designs was
built, tested, and approved for deployment on the three
ST5 spacecraft, which were successfully launched into
space on 22 March 2006. This evolved antenna design is
the first computer-evolved antenna to be deployed for
any application and is the first computer-evolved
hardware in space.",

multi-objective components. Randomised to simulate
manufacturing errors. Take _worse_ fitness in order to
