Class NonLinearConjugateGradientOptimizer.BracketingStep

  • All Implemented Interfaces:
    OptimizationData
    Enclosing class:
    NonLinearConjugateGradientOptimizer

    @Deprecated
    public static class NonLinearConjugateGradientOptimizer.BracketingStep
    extends java.lang.Object
    implements OptimizationData
    Deprecated.
    As of v3.3, this class is not used anymore. This setting is replaced by the initialBracketingRange argument to the new constructors.
    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
