Description

Interface Summary
Preconditioner: This interface represents a preconditioner for differentiable scalar objective function optimizers.

Class Summary
NonLinearConjugateGradientOptimizer: Non-linear conjugate gradient optimizer.
NonLinearConjugateGradientOptimizer.BracketingStep: The initial step is a factor with respect to the search direction (which itself is roughly related to the gradient of the function).
NonLinearConjugateGradientOptimizer.IdentityPreconditioner: Default identity preconditioner.

Enum Summary
NonLinearConjugateGradientOptimizer.Formula: Available choices of update formulas for the updating the parameter that is used to compute the successive conjugate search directions.
