Well, it's too long so I'm not going to elaborate ;>
But I think the problem here is defining what a "better" result is.
(Neccesary for genetic algorithms)
There are 2 "quality" measurements to be made of an mp3 algorithm.
Endfile size, and how it sounds.
A third is possibly speed of the algorithm, but that doesn't really
matter.
File size is easy enough to measure, but "sound quality" is not.
It is purely subjective.
VERY HARD to define on a computer.
Really, the only way I see is to exactly model the ear and brain's
response to the entire fange of frequencies and amplitudes.
And then, all combinations of all frequencies and amplitudes.
Then you'd have to take each result and pass it through the ear-brain
model and compare it to the raw-source-through-ear/brain model.
As you can see, it's not going to happen.
