java.lang.Objectorg.apache.commons.math3.optimization.direct.BaseAbstractMultivariateOptimizer<FUNC>
FUNC - Type of the objective function to be optimized.
@Deprecated public abstract class BaseAbstractMultivariateOptimizer<FUNC extends MultivariateFunction>
Base class for implementing optimizers for multivariate scalar functions. This base class handles the boiler-plate methods associated to thresholds, evaluations counting, initial guess and simple bounds settings.
