Abstract
One characteristic tendency of genetic programming is
the production of considerably larger trees than
expected. It has been suggested that this is related to
the ability of individuals to replicate accurately. In
this paper we present theoretical analysis which shows
that, for certain specific cases, the pressure for
accurate replication induces an increase in tree size.
In particular, we show that among fit individuals,
larger trees are more likely to yield semantically
equivalent children...
