mutation_mean: /mean mutation for DE

In ExpDE: Modular Differential Evolution for Experimenting with Operators

Description

Implements the "/mean/nvecs" mutation for the ExpDE framework

Usage

mutation_mean(X, mutpars)

Arguments

X	population matrix
mutpars	mutation parameters (see Mutation parameters for details)

Value

Matrix M containing the mutated population

Mutation Parameters

The mutpars parameter contains all parameters required to define the mutation. mutation_mean() understands the following fields in mutpars:

• f : scaling factor for difference vector(s).
  Accepts numeric vectors of size 1 or nvecs.

• nvecs : number of difference vectors to use.
  Accepts 1 <= nvecs <= (nrow(X)/2 - 2)
  Defaults to 1.
