[P2 | 8h] Create a complex world

[andypyrope]

NOTE: This world probably won't be useful for actual straightforward evolution. It's mostly just for fun, hence the low priority.

Organism constants (DNA-defined)

• Genders (g - [0; 1)) - male organisms choosing female ones, after which female ones filter them out
  • Gender can be in the form of a double in the [0; 1) range. Every generation all organisms pick a temporary effective gender - male, female or asexual. The chance, if the gender coefficient is g, is as follows:
    • female: Math.max(0.5 - g, 0.0) -- chooses males based on their resources/fitness; receives resources from the chosen males but when giving birth, loses a preset part of her resources; doesn't know how much the males give,
    • male: Math.max(g - 0.5, 0.0) -- chooses females based on their fitness; gives resources to the ones who choose him
    • asexual: otherwise (the chance is technically 1.0 - Math.abs(0.5 - g))
• Food/resources (r - (0; 1]) - every generation a set amount is given away and spread across the organisms, with the fittest ones receiving the most resources; an organism with 0 food dies; studying (training its neural network, etc.) costs resources. Any resources greater than 1.0 at the end of a generation are cut down to 1.0.
• Care coefficient (c - [0; 1)). This one has 2 applications:
  • what part of their resources a parent gives to their child every generation
  • what part of their resources a male gives to a female
• Studying coefficient (s - [0; 1)) - how much of their resources an organism is willing to spend for studying each generation
• Promiscuity (p - [0; 1)) - what ratio of the available mates an organism would choose

World constants

• Hunger rate (H - [0; 1)) - the amount of resources taken away from every organism (indiscriminately) each generation
• N (N - natural number) - the average number of organisms. The resources given away each generation are equal to h * n. The number of organisms can go up or down but they should balance out around n
• Max studying complexity (S - big natural number, e.g. 1 000 000) - the max number of computations an organism is allowed to make. The price of x computations is equal to x / S. Every generation an organism decides to allocate r * s resources for studying. If one studying iteration consists of x computations, then the organism will make (r * s) / (x / S) studying iterations. Any leftover resources remain in the organism.

TODO: Figure out how to make resource distribution fair. Another world constant may be necessary for this.
