cmaSamplePopulation {rCMA}

Sample a population from the current CMA-ES distribution.

Description

The population size is given by cmaGetPopulationSize(cma). It can be either set manually with cmaSetPopulationSize(cma,p), prior to cmaInit(cma), or CMA-ES will use the default population size
popSize = 4 + 3*log(dimension).

Usage

cmaSamplePopulation(cma)

Arguments

cma

CMA-ES Java object, already initialized with cmaInit

Value

popR, a (dimension x popSize) matrix with popR[,1] being the first individuum in the population.
dimension = cmaGetDimension(cma)
popSize = cmaGetPopulationSize(cma)
