This bot seems to do well, as in it destroys the previous entry. It constantly fires ties, which allows it to capture food from a distance. The gain of capturing more food most likely outweighs the cost of extra tie firing. If the bot fires a tie at conspec, it is repelled and deletes the tie. This has the benifit of sending offspring away to find more food.
