Genghis Rabbit Hordes

Ran through a 2000+ day simulation over night. The days start to drag as the number of animals increase. The early part revealed a few bugs I had on removing dead rabbits. I also saw a big trend when there are a lot of rabbits running around looking for something to eat. I'll call it the Genghis Rabbit Horde affect. The rule for the rabbits was to eat then move to the best place to eat next ("The grass is always greener rule"). This led to a horde of rabbits moving together from one cell to the next. The bad thing is that the horde would get so big that not all of the rabbits would have something to eat. This led to massive die offs from starvation. I expect boom bust cycles, but I think this pattern exaggerates the cycle magnitude.

I set up a simple history tracking table, at the end of each day it takes the average vitality of the cells in the grid and the number of rabbits. I'll post some pictures of the graphs later after going through several runs.

I made a change in the order of what the rabbits do. It moves to a new cell then eats. Hopefully this will cut down on the horde affect.
