Class NonLinearConjugateGradientOptimizer.BracketingStep
java.lang.Object
org.apache.commons.math3.optim.nonlinear.scalar.gradient.NonLinearConjugateGradientOptimizer.BracketingStep
- All Implemented Interfaces:
- OptimizationData
- Enclosing class:
- NonLinearConjugateGradientOptimizer
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
