Class BaseAbstractMultivariateSimpleBoundsOptimizer<FUNC extends MultivariateFunction>

java.lang.Object
  org.apache.commons.math3.optimization.direct.BaseAbstractMultivariateOptimizer<FUNC>
      org.apache.commons.math3.optimization.direct.BaseAbstractMultivariateSimpleBoundsOptimizer<FUNC>

Type Parameters:

FUNC - Type of the objective function to be optimized.

All Implemented Interfaces:

BaseMultivariateOptimizer<FUNC>, BaseMultivariateSimpleBoundsOptimizer<FUNC>, BaseOptimizer<PointValuePair>

Direct Known Subclasses:

BOBYQAOptimizer, CMAESOptimizer

@Deprecated
public abstract class BaseAbstractMultivariateSimpleBoundsOptimizer<FUNC extends MultivariateFunction>
extends BaseAbstractMultivariateOptimizer<FUNC>
implements BaseMultivariateOptimizer<FUNC>, BaseMultivariateSimpleBoundsOptimizer<FUNC>

Base class for implementing optimizers for multivariate scalar functions, subject to simple bounds: The valid range of the parameters is an interval. The interval can possibly be infinite (in one or both directions). This base class handles the boiler-plate methods associated to thresholds settings, iterations and evaluations counting.
