Evo

Environment for testing natural selection processes on some digital "bugs"

Key Parameters:

W, width of canvas [pixels]
H, height of canvas [pixels]

D_f, diameter of food [pixels]
P_f, period of food generation [ticks]

D_b, diameter of bug [pixels]
V_b, maximum velocity of a "bug" [pixels/tick]
S_b, number of bugs "spawned" when food eaten [bugs]
H_b, number of ticks a bug can go without food before death [ticks]

Key Behaviors

- Bug acceleration is "random" in 2D space but velocity never exceeds V_b
- The canvas is "infinite" (i.e. if bug wanders off left side it will appear on right side, and vice versa)
- Upon encountering food, a bug will eat it.  The polygon representing the bug and the food must intersect.
- If a bug goes length of time H_b without eating food it will disappear from simulation
- Upon eating food, the bug will become completely "full" and will instantly generate offspring of amount S_b
- Every amount of time P_f, a unit of food is placed randomly on the canvas
