void	Square2ModelData.buildModel ()
	adds variables and constraints to the model

double	Square2ModelData.evaluateNonlinearTerm (double[] x, int rowno, boolean ignerr, int thread)
	callback method for evaluating the nonlinear terms in a given row

void	Square2ModelData.evaluateNonlinearJacobian (double[] x, double[] jac, int rowno, int[] jacnum, boolean ignerr, int thread)
	callback method for evaluating the jacobian for the nonlinear terms in a given row

Detailed Description

A square model where we pretend that the second constraint is completely nonlinear.

\[ x1 + x2 = 10 \]

\[ x1 - x2 = 0 \]

\[ x1 + x2 \leq 9 \]

In a second case we change the Rhs in the inequality to 11 so the model becomes feasible.

For more information about the individual callbacks, please have a look at the source code.

double Square2ModelData.evaluateNonlinearTerm	(	double[]	x,
		int	rowno,
		boolean	ignerr,
		int	thread )

inline

callback method for evaluating the nonlinear terms in a given row

Parameters

x	the solution vector that needs to be evaluated.
rowno	the number for the row in which the nonlinear term exists.
ignerr	a boolean to indicate whether the current point is safe or unsafe.
thread	the index of the thread from which this method is being called from.

Notes: an error in the evaluation is reported by calling errorInEvaluation()

void Square2ModelData.evaluateNonlinearJacobian	(	double[]	x,
		double[]	jac,
		int	rowno,
		int[]	jacnum,
		boolean	ignerr,
		int	thread )

inline

callback method for evaluating the jacobian for the nonlinear terms in a given row

Parameters

x	the solution vector that needs to be evaluated.
jac	an array to store the Jacobian at the given point and row. This is of length numVar().
rowno	the number for the row in which the nonlinear term exists.
jacnum	vector with a list of column numbers for the nonlinear nonzero Jacobian elements in the row.
ignerr	a boolean to indicate whether the current point is safe or unsafe.
thread	the index of the thread from which this method is being called from.
