This sounds good. I don't know a lot about GAs, so if others have
insight, that would be great. It would also be handy if you could put
up a section on the Wiki about GAs and maybe post some links to basic
papers there, so people that aren't familiar can go do some background
reading.
I
Conceptually, at least, it would be good to have the option for fitness
functions to be expressed as map-reduce programs. Unfortunately, having
mappers spawn MR programs runs the real risk of dead-lock, especially on
less than grandiose clusters.
To me, that indicates that if the fitness function

How about writing the population to the file and using it as input to
map-reduce directly? Evaluations that fit into a map can obviously handle
that. Evaluations that need to be parallelized, can have the map emit
multiple copies with sequential keys. This will put a copy of each input
into mult

This is exacly what I did in [Mahout-56]

I found a cool introduction to evolutionary algorithms, I added it to the wiki
if someone is interested...
