## 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.
  As of 3.1 (to be removed in 4.0).

      @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.
  Since:
    3.0
