recombination_geo {ExpDE}

Geometric recombination for DE

Description

Implements the "/geo" (geometric) recombination for the ExpDE framework

Usage

recombination_geo(X, M, recpars)

Arguments

X

population matrix (original)

M

population matrix (mutated)

recpars

recombination parameters (see Recombination parameters for details)

Value

Matrix U containing the recombined population

Recombination Parameters

The recpars parameter contains all parameters required to define the recombination. recombination_geo() understands the following fields in recpars:

• alpha : exponent for geometrical recombination.
  Accepts numeric value 0 <= alpha <= 1 or NULL (in which case a random value is chosen for each recombination).
