  abstract =     "Recent research [1] has found that standard sub-tree
                 crossover with uniform selection of crossover points,
                 in the absence of fitness pressure, pushes a population
                 of GP trees towards a Lagrange distribution of tree
                 sizes. However, the result applied to the case of
                 single arity function plus leaf node combinations,
                 e.g., unary, binary, ternary, etc trees only. In this
                 paper we extend those findings and show that the same
                 distribution is also applicable to the more general
                 case where the function set includes functions of mixed
                 arities. We also provide empirical evidence that
                 strongly corroborates this generalisation. Both
                 predicted and observed results show a distinct bias
                 towards the sampling of shorter programs irrespective
                 of the mix of function arities used. Practical
                 applications and implications of this knowledge are
                 investigated with regard to search efficiency and
                 program bloat. Work is also presented regarding the
                 applicability of the theory to the traditional
                 0.90-function 0.10-terminal crossover node selection
                 policy.",
