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