Class NonLinearConjugateGradientOptimizer.BracketingStep

java.lang.Object
org.apache.commons.math3.optim.nonlinear.scalar.gradient.NonLinearConjugateGradientOptimizer.BracketingStep
All Implemented Interfaces:
OptimizationData
Enclosing class:
NonLinearConjugateGradientOptimizer
@Deprecated public static class NonLinearConjugateGradientOptimizer.BracketingStep extends 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
