Class DifferentiableMultivariateVectorMultiStartOptimizer

java.lang.Object

org.apache.commons.math3.optimization.BaseMultivariateVectorMultiStartOptimizer<DifferentiableMultivariateVectorFunction>

org.apache.commons.math3.optimization.DifferentiableMultivariateVectorMultiStartOptimizer

All Implemented Interfaces:

BaseMultivariateVectorOptimizer<DifferentiableMultivariateVectorFunction>, BaseOptimizer<PointVectorValuePair>, DifferentiableMultivariateVectorOptimizer

Deprecated.

As of 3.1 (to be removed in 4.0).

@Deprecated
public class DifferentiableMultivariateVectorMultiStartOptimizer
extends BaseMultivariateVectorMultiStartOptimizer<DifferentiableMultivariateVectorFunction>
implements DifferentiableMultivariateVectorOptimizer

Special implementation of the DifferentiableMultivariateVectorOptimizer interface addind multi-start features to an existing optimizer. This class wraps a classical optimizer to use it several times in turn with different starting points in order to avoid being trapped into a local extremum when looking for a global one.

Since:

2.0

DifferentiableMultivariateVectorMultiStartOptimizer

public DifferentiableMultivariateVectorMultiStartOptimizer(DifferentiableMultivariateVectorOptimizer optimizer,
                                                   int starts,
                                                   RandomVectorGenerator generator)

Deprecated.

Create a multi-start optimizer from a single-start optimizer.

Parameters:

optimizer - Single-start optimizer to wrap.

starts - Number of starts to perform (including the first one), multi-start is disabled if value is less than or equal to 1.

generator - Random vector generator to use for restarts.
