cmaInit: Initialize a CMA-ES Java object.

In rCMA: R-to-Java Interface for 'CMA-ES'

Initialize a CMA-ES Java object.

Description

Initialize a CMA-ES Java object.

Usage

cmaInit(cma, seed = NULL, dimension = NULL, initialX = NULL,
  initialStandardDeviations = NULL)

Arguments

cma	CMA-ES Java object, as created by cmaNew
seed	[NULL] if not NULL, set the seed to the given value
dimension	[NULL] if not NULL, overwrite the dimension setting from propFile (cmaNew)
initialX	[NULL] if not NULL, overwrite the initialX setting from propFile (cmaNew). initialX can be a double or a double vector of length dimension.
initialStandardDeviations	[NULL] if not NULL, overwrite the initialStandardDeviations setting from propFile cmaNew. initialStandardDeviations can be a double or a double vector of length dimension.

Value

fitness, a vector of 0's with the length of the intended population.

Note

As a side effect, the CMA-ES Java object cma of class CMAEvolutionStrategy is transferred into an augmented state. As a second side effect, the population size is set to

λ = 4 + 3 floor(ln(n))

where n=dimension.
