xegaGpAllCross2Gene {xegaGpGene} | R Documentation |
Crossover of 2 derivation tree genes.
Description
xegaGpAllCross2Gene()
swaps two randomly extracted
subtrees between 2 genes. Subtrees must have the same
root in order to be compatible. The current implementation
performs at most lF$MaxTrials()
trials to find compatible
subtrees. If this fails, the original genes are returned.
Usage
xegaGpAllCross2Gene(ng1, ng2, lF)
Arguments
ng1 |
Derivation tree. |
ng2 |
Derivation tree. |
lF |
Local configuration of the genetic algorithm. |
Details
Crossover is controlled by one local parameter:
-
lF$MaxTrials()
: Maximal number of trials to find compatible subtrees. If compatible subtrees are not found, the gene is returned unchanged.
Value
List of 2 derivation trees.
