However, in GGGP, and in the research presented in this chapter,
this is generally not an issue, because in both fields of research, the derivations
of the individuals/examples from the given grammar are preserved, and thus
correct, unique derivations are known.

For example, a common SCFG grammar for the symbolic regression prob-
lem is illustrated in Fig. 6.10. An individual, which may be derived or sampled
from this grammar, is illustrated in Fig. 6.11. The individual in Fig. 6.11 is
derived by applying the following sequence of rules. Starting from the starting
symbol S, rule 0 is chosen to rewrite S and obtain
Exp Op Exp.
