cmaInit function

Initialize a CMA-ES Java object.

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.

Returns

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

where $n=$dimension.

Examples

cma <- cmaNew();
   cmaInit(cma,seed=42,dimension=2,initialX=1.5);
