Enum ConjugateGradientFormula
java.lang.Object
java.lang.Enum<ConjugateGradientFormula>
org.apache.commons.math3.optimization.general.ConjugateGradientFormula
- All Implemented Interfaces:
Serializable
,Comparable<ConjugateGradientFormula>
Deprecated.
As of 3.1 (to be removed in 4.0).
Available choices of update formulas for the β parameter
in
NonLinearConjugateGradientOptimizer
.
The β parameter is used to compute the successive conjugate search directions. For non-linear conjugate gradients, there are two formulas to compute β:
- Fletcher-Reeves formula
- Polak-Ribière formula
- Since:
- 2.0
