## Class NonLinearConjugateGradientOptimizer.BracketingStep

- java.lang.Object
- - org.apache.commons.math3.optim.nonlinear.scalar.gradient.NonLinearConjugateGradientOptimizer.BracketingStep

- All Implemented Interfaces:
    OptimizationData
  Enclosing class:
    NonLinearConjugateGradientOptimizer

  Deprecated.
  As of v3.3, this class is not used anymore. This setting is replaced by the `initialBracketingRange` argument to the new constructors.

      @Deprecated
      public static class NonLinearConjugateGradientOptimizer.BracketingStep
      extends Object
      implements OptimizationData

  The initial step is a factor with respect to the search direction (which itself is roughly related to the gradient of the function).
  It is used to find an interval that brackets the optimum in line search.
  Since:
    3.1
