   The design of the InvaderZ is his genome and the way it behaves. It as vector of size 16 with zeros or ones. If it's a one it draws a "pixel". So you have to think of it as a 4x4 Matrix ```[ 0,0,1,1, 0,0,1,1, 1,1,1,1, 0,1,1,

   I don't have a server; I pay a hosting service, it's what I can afford right now, and I called them and asked for more resource, cause it's been receiving a lot of visitors. Maybe it went down for a moment.

   the manifest.appcache should take care of the update; but if it don't, clear the storage and visit victorribeiro.com/invaderz again

    I'm inserted in a context that I don't have anyone to discuss this kind thing, so you don't have to be apologetic. It was very that you liked the project. I've been receiving many suggestions and I'll look into them

    The idea began with me wanting to generate space Invaders character design using genetic algorithm, so I thought, what the heck: if I do that I might as well do a sort of game play to justify they design. That's how this project was bo

    But do you agree that if they don't move, they will the ones easier to shoot? So, unless you are sparing them, they won't go very far and will have less chance of reproduction.

    No, their fit score is how close they got to crossing the finish line. If they don't move, they got no score. If they move in a straight line and still manage to win, hey, that's life. I've observed that the ones who jiggle a

    Yes, and the last one who survived moved in a way that helped it survive. It's not the best one the ones who reproduce, they all can reproduce, the ones who got closer or went through have more chance.

    They evolve each generation. What happens after the 7 generation is that if no one could kill you until now, make a new wave of Invaders while keeping the best one from past generations.

    It's the second time I'm posting this here, I know; but it is now a lot faster than before, so I thought to show it again.

    My end goal is to have this implement on a file explorer, so you can list your pictures by name, date, type or similarity.

    We could get a dataset of images and see how each one does. Mine is very simple. It uses a histogram as features and could use the width and height of the image as well, if you pass the flag -s
