Pictures:

Note: In some of the pics, I have optimized the yellow dots so that some of them arn't drawn. They are still there, but just not drawn to save on processing.
White trees are newly born, black trees are about to die.

These pics have mostly the same constants, you can see different strategies evolve.

The next set of trees are under different constants, along with one that decreased their branch size slightly since they were getting too big.
