xegaGeDecodeGene {xegaGeGene} | R Documentation |
Decode a binary gene for a context-free grammar.
Description
xegaGeDecodeGene()
decodes a binary gene with
a context-free grammar.
Usage
xegaGeDecodeGene(gene, lF)
Arguments
gene |
Binary gene. |
lF |
Local configuration of the genetic algorithm. |
Details
The codons (k-bit sequences) of the binary gene determine the choices of non-terminal symbols of a depth-first left-to-right tree traversal. Decoding works in 3 steps:
From the binary gene and a grammar a potentially incomplete derivation tree is built.
The leaves of the derivation tree are extracted.
By reusing the random integer vector and by using a non-recursive grammar, all non-terminals are randomly completed.
It is guaranteed that a complete and syntactically correct program is returned.
Value
Decoded gene.
