public static class CMAESOptimizer.PopulationSize extends Object implements OptimizationData
Population size. The number of offspring is the primary strategy parameter. In the absence of better clues, a good default could be an integer close to 4 + 3 ln(n), where n is the number of optimized parameters. Increasing the population size improves global search properties at the expense of speed (which in general decreases at most linearly with increasing population size).
