NAME

crittering - Evolving Artificial Life

SYNOPSIS

critterding [OPTION]...

DESCRIPTION

This manual page was written for the Debian distribution because critterding does not have a manual page. It provides information taken from "critterding --help" output and project homepage.

Critterding is a "Petri dish" universe in 3D that demonstrates evolving artificial life. Critters start out with completely random brains and bodies, but will automatically start evolving into something with much better survival skills.

Critters are informed by sensors:

Critters can make use of the following motor neurons (actions):

At default, the program sets up a small world with a relatively large amount of food units and keeps throwing in critters with randomly generated brains and bodies.

After a while, one of these idiot critters will unavoidably be good enough to maintain a small population:

Slowly but surely, their behaviour will become a lot less random as they demonstrate increasingly better survival skills.

KEYS

To save current settings to a profile, press "s" in the simulation. It will be saved to ./default and can be loaded by using "--profile ./default"

Use F1 in the simulation for more information about keys.
