Sexy NASA genetic algorithm recommends killing 2/3 of crew so remaining crew will survive longer

Perhaps some explanation is in order.
Came across anecdote here:  https://www.gwern.net/Tanks 
"NASA Mars mission planning, optimizing food/water/electricity consumption for total man-days survival, yields an optimal plan of killing 2/3 crew & keep survivor alive as long as possible"

Reference, though, is this single forum post with no names or dates:  https://lobste.rs/s/1d7whd/tales_from_trenches_ai_disaster_stories#c_le6tsr 

It does seem more plausible than some anecdotes, though. The framework and survival length thresholds match those in this paper (which doesn't use a GA but suggests it as a possible future approach).  https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20110008543.pdf 

(If anyone knows of a reference that will confirm this anecdote, please please let me know!)
