%description
Derivation tree operations are needed for implementing grammar-based
genetic programming and grammatical evolution: Generating of a random
derivation trees of a context-free grammar of bounded depth, decoding a
derivation tree, choosing a random node in a derivation tree, extracting a
tree whose root is a specified node, and inserting a subtree into a
derivation tree at a specified node. These operations are necessary for
the initializiation and for decoders of a random population of programs,
as well as for implementing crossover and mutation operators. Depth-bounds
are guaranteed by switching to a grammar without recursive production
rules. For executing the examples, the package 'BNF' is needed. The basic
tree operations of generating, extracting, and inserting of derivation
trees as well as the conditions for guaranteeing complete derivation trees
have been presented in Geyer-Schulz (1997, ISBN:978-3-7908-0830-X). The
use of random integer vectors for the generation of derivation trees has
been introduced in Ryan, C., Collins, J. J., and O'Neill, M. (1998)
<doi:10.1007/BFb0055930>.
