java.lang.Object

org.apache.commons.math3.optimization.BaseMultivariateMultiStartOptimizer<DifferentiableMultivariateFunction>

org.apache.commons.math3.optimization.DifferentiableMultivariateMultiStartOptimizer

All Implemented Interfaces:

BaseMultivariateOptimizer<DifferentiableMultivariateFunction>, BaseOptimizer<PointValuePair>, DifferentiableMultivariateOptimizer

Deprecated.

As of 3.1 (to be removed in 4.0).

@Deprecated
public class DifferentiableMultivariateMultiStartOptimizer
extends BaseMultivariateMultiStartOptimizer<DifferentiableMultivariateFunction>
implements DifferentiableMultivariateOptimizer

Special implementation of the DifferentiableMultivariateOptimizer interface adding 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

DifferentiableMultivariateMultiStartOptimizer

public DifferentiableMultivariateMultiStartOptimizer(DifferentiableMultivariateOptimizer optimizer,
                                                     int starts,

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.
