  • Are there enough cows?

    In nature, aren't there usually more prey than hunters?

    Long-term, so long as not _all_ prey are eaten, the population of both hunter and prey should balance each other. When the prey is scarce, the hunters starve.

    Do you have a "fiercness" dimension on the tigers? Maybe they could learn to back off? :)
    • In a predator/prey system with only two species you usually get an oscillating system, where the number of individuals in each species varies in a sine curve, with the predators lagging behind the prey.

      Adding more species, eg grass that the prey 'preys on', gives a more interesting picture...

      • Adding more species ...

        Long term, that's my plan. I want to add bodies of water, larger maps (it's only 30x30 right now) and omnivores. First, though, I have to get it working :)

    • I keep the number of predators and prey from falling below a certain preset value for each; they'd go extinct before they'd evolve. Currently, they each hover at at 9 to 10 animals.

      I could add new traits to the tigers, but for now, I want to see what's wrong (if anything) with my model. The cows have bumped up to a maximum bloodstream of four generations and when this happened, my "world data" file was rewritten. In checking that, I saw some very curious results which I think are indicative of a bug in
