This interesting answer to the question Do antenna farms on spacecraft make any sense or are they purely aesthetic? in Worldbuilding SE links to the NASA Ames page 'Borg' Computer Collective Designs NASA Space Antenna. The clever title refers to a small rack of computers working together using evolutionary design algorithms to iteratively adapt a design in funny ways to obtain a certain set of performance specification.
The link says:
Like a friendly, non-biological form of the Borg Collective of science fiction fame, 80 personal computers, using artificial intelligence (AI), have combined their silicon brains to quickly design a tiny, advanced space antenna.
If all goes well, three of these computer-designed space antennas will begin their trip into space in March 2006, when an L-1011 aircraft will take off from Vandenberg Air Force Base in California. The airplane will drop a Pegasus XL rocket into the sky high above the Pacific Ocean. The rocket will ignite and carry three small Space Technology (ST5) satellites into orbit.
Each satellite will be equipped with a strange-looking, computer-designed space antenna. Although they resemble bent paperclips, the antennas are highly efficient, according to scientists.
It continues, and has other links.
The NASA Computational Sciences Division Intelligence Report 2004 says:
The Evolvable Systems Group’s evolved antennas are being prepared for tests that will determine if they are flight qualified for the mission scheduled to orbit in the Earth's magnetosphere after 2004.
The New Millennium Program’s Space Technology 5 (ST5) mission will test multiple technologies and mission concepts in Earth’s orbit for future use. Each technology represents a breakthrough in performance, capability or application in a new and unique manner. Once launched with ST5, the antennas will be the first evolved hardware ever flown on a NASA mission. On ST5 the antenna will both relay satellite data to the ground and accept commands sent from Earth to the satellites.
The evolved antenna is a product of evolvable systems research, an emerging set of computer methods using algorithms that are creative and are termed invention machines because of their demonstrated ability to produce patentable inventions.
The Question: Have these evolved antenna tests taken place? Did it go well? Have subsequent antenna designs based on this kind of algorithm ever been used in spacecraft beyond the preliminary testing stages?
I found this larger version of the same image in the links in this thread but I can't read German. There's a similar image on page 18 in http://cerna-ethics-allistene.org/digitalAssets/48/48092_cerna_apprentissage_mouret_juin_2016.pdf which says "Hornby et al. 2011" but I can't read this either.
