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
