Abstract
In steady state Twin GP both children created by sub-tree crossover and point mutation are used. They are born together and die together. Evolution is little changed. Indeed fitness selection using the twin’s co-conceived doppelganger is possible.

Notes
- 1.
According to the binomial distribution the first three variants of twin GP, i.e. twin, mean and max, are not significantly worse than TinyGP without twins.
- 2.
For the small trees the distribution is only approximately binomial (Langdon 2009).
