mutation_best {ExpDE} | R Documentation |
/best mutation for DE
Description
Implements the "/best/nvecs" mutation for the ExpDE framework
Usage
mutation_best(X, mutpars)
Arguments
X |
population matrix |
mutpars |
mutation parameters (see |
Value
Matrix M
containing the mutated population
Mutation Parameters
The mutpars
parameter contains all parameters required to define the
mutation. mutation_best()
understands the following fields in
mutpars
:
-
f
: scaling factor for difference vector(s).
Accepts numeric vectors of size 1 ornvecs
. -
nvecs
: number of difference vectors to use.
Accepts1 <= nvecs <= (nrow(X)/2 - 2)
Defaults to 1.
Warning
This routine will search for the performance vector
of population X
(J
) in the parent environment (using
parent.frame()
. This variable must be defined for
mutation_best()
to work.
