[SPAM] darwin crap

hi been playing around with genetic algorithms a bit so
here's the first test result, i call it "LAZYBARF".
it's generatively real time sequenced with fancy
custom software, that's why all the girls love it too.

It's going to be No.1 all over the world!

I find music based on code interesting. As far as enjoyment
of listening to it, it was ok but nothing that special I
guess imo. Some argue that you can ignore jivverdicker
because he's a fag's supernumerary nipple.

thanks and yeah i'm really not happy with it myself, had to
spam it either way. this whole generative stuff proves to be
more difficult in detail than imagined, actually i wanna
trash mah computer now and plant tomatoes instead.

this is excellent and makes much more sense than crunching
numbers, thanks :D

Interesting.

BTW, your avy is a jerkface.

LAZYBARF V2 might be better but maybe not. It's shorter
sequences and i left out scale modulation.

on topic, the track sounds cool, reminds me of this:

due to astounding public demand, here's more genetic LAZYBARF.

I like v2, care to share/explain more about this? also, it
is genetic sequencing I guess, so you input a patch and a
basic pattern to evolve from?

so what it is is 2 instances of a monophonic sequencer with
variable step length (steps are spread across different
channels though, i'm using 12 channels in Ableton)... at the
beginning it creates one semi-random target sequence and a
population of 2000 random sequences, then there's fitness
evaluation/selection/mutation/mating of the fittest. what
you hear is always the current fittest sequence, i.e. the
one which is closest to target... so after a while when the
population has evolved really close to the target sequence,
a new target is generated and so on.
the genome, i.e. the sequence parameters, is mainly note
values/step lengths/channels/velocity in this case... this
is just first baby steps in GA for me, like mentioned above
i'm not happy with it so far. I want to have an evolving eco
system where different "species" (phrases, patterns, ...)
compete for survival, but this will be really complex to
build.... and several magnitudes more difficult to make it
sound nice, that's actually the most daunting part - which
parameters are mapped to what and what values do they have
:D

so it does compute another generation each measure? If not I
don't get it


 

offline Terence Hill from Germany on 2009-11-06 17:15 [#02342621]

it does compute ~50 generations per second, only the
sequencer is updated with new data after each measure. i've
built on top of this example...
so yeah it's very basic GA - the goal is known from the
beginning, then there's evolution from random numbers
towards this goal. more interesting would be fitness
evaluation based on some kind of arbitrary, unknown,
"aesthetic survivability" but ehhhh, try to teach a machine
what's aesthetically pleasing...

It's a trivial game on the pseudo academic level but it
sounds shit. What are you trying to say?

It's not hard if you pick some great music and apply that to
well thought out algorithms. You still need an idiot doing
stuff to make it whole.

that's was my quirk, if you know the target and you try to
best fit you get something that is 99,9% similar to the
target, no? yet there are variations in that last piece so
well, it's nice
