Detailed Description

Class for calculator for the least-square equality constraint multipliers.

The Calculate method of this class computes the least-square estimate for the y_c and y_d multiplers, based on the current values of the gradient of the Lagrangian.

Member Function Documentation

virtual bool Ipopt::LeastSquareMultipliers::InitializeImpl	(	const OptionsList &	options,
		const std::string &	prefix
	)			[virtual]

overloaded from AlgorithmStrategyObject

Implements Ipopt::EqMultiplierCalculator.

virtual bool Ipopt::LeastSquareMultipliers::CalculateMultipliers	(	Vector &	y_c,
		Vector &	y_d
	)			[virtual]

This method computes the least-square estimates for y_c and y_d at the current point.

The return value is false, if the least square system could not be solved (the linear system is singular).

Implements Ipopt::EqMultiplierCalculator.

void Ipopt::LeastSquareMultipliers::operator=

(

const LeastSquareMultipliers &

)

[private]

Overloaded Equals Operator.

Reimplemented from Ipopt::EqMultiplierCalculator.
