| xegaGeGeneMapmLCM {xegaGeGene} | R Documentation |
Map the bit strings of a binary gene to integer parameters in the interval
1 to numbers::mLCM(x) < 2^k.
Description
xegaGeGeneMapmLCM()
maps the bit strings of a binary string
to integers in the interval 1 to
lF$CodonPrecision().
Bit vectors are mapped into equispaced numbers in the interval.
Usage
xegaGeGeneMapmLCM(gene, lF)
Arguments
gene |
Binary gene (the genotype). |
lF |
Local configuration. |
Details
Using the interval of 1 to numbers::mLCM(1:m)
provides a the least common multiple of all prime factors
of the numbers in the interval 1:m.
This corresponds to the bucket rule of Keijzer et al. (2002).
For 16-bit precision, the highest number of rules
for the same non-terminal symbols is 12.
For 8-bit precision,this reduces to 6.
With 64-bit integer arithmetic, the bucket rule works up to
42 rules starting with the same non-terminal.
Value
Integer vector.
