alt Hacker NewsI've been working on a surprisingly similar project for the last week: plants grow cells on a grid by executing a raw chunk of memory according to a simple instruction set. I'm aiming more for an evolution simulator, where each plant gets a 1kb brain that is randomized a little when a new plant is spawned.
Most plants right now settle into a simple goto loop that places the requisite cells to survive and then spam seeds until they die. I have seen some interesting variety in body plans emerge where plants sort into discrete species regionally. I'm hoping to eventually get decision making to emerge organically. If things go well this system is theoretically capable of sexual selection (and maybe fisherian runaway) but that's a pipe dream right now.
