 - The behavioral distances between node ''i'' and every node ''j'' from `parent1` are computed using a formula that takes into account the minimum and maximum values computed by the two nodes during evaluation:

 - The sampling semantic distance (SSD) between two nodes (subtrees) is defined as the absolute mean between their corresponding sampling semantics:

 The crossover procedure chooses a crossover point from `parent0`, then picks the first node in `parent1` that satisfies the similarity condition (5).
