Help Forum How do cellular automata work?    deadhumourist      3/6/2010 I've recently read about the C3/DS IQ test, and it seems really interesting, but I'm a little confused. So this is a two part question. Apparently, cellular automata enters through the foot of the creature. So how are they supposed to know the food is elsewhere? Is the iq test designed to test their instinct to actively go look for food? And the other part of the question.. How do dispensers fit into it all? I've found that when the food is lying somewhere, the norns eat it. When there's a dispenser however, they don't seem to know that pushing it contains food, even though they have been taught so.   Prodigal Sock Ghosthande     3/6/2010 Norns tell where food is by following the smell to its strongest point (likely by comparing CA levels between adjoining rooms). Then they just happen across the food item once they're there. That's why if you make a non-food agent emit food smell, the Norn will wander aimlessly in that location trying to "get food" when it isn't there. The dispenser thing just seems to be a regular problem with how the game works. Although Norns even have an instinct telling them to use dispensers when hungry, pushing a dispenser just isn't as rewarding as actually eating food, so it seems to get shoved to the sidelines for lack of reinforcement. The alternative would be to bump up the reinforcement value, but then Norns would become dispenser-obsessed and stop eating. Norn genes and brains are too simplistic for things like dispensers to be really effective. They just don't support sequences of behaviors too well.   Malkin Manager     3/6/2010 Norns (and some agents) can tell the gradient of a CA across rooms - that's why the gnarlers from the ettin desert never fall into the water, they smell it and retreat from large concentrations of water smell. For more information on CAs, there's fuzzie's tutorial. Moe's Room Changer agent is fun - it will give you a crash course in CAs. There's also this thread for more information. The IQ test seems to test their ability to realise that hey, getting to food / norn home is more important than kisspopping or slapping other norns, and tests the norn's ability to use lifts and doors appropriately. My TCR Norns   deadhumourist   3/10/2010 Ah, thanks Ghosthande and Malkin! I actually do have the room changer, I use it to make the desert terrarium fertile to plant things.
