Function Documentation

evaluateNonlinearTerm()

pyconopt.ModelData.evaluateNonlinearTerm	(		self,
			x,
			rowno,
			ignerr,
			thread )

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.

Returns

the value of the nonlinear terms.

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

Reimplemented in qp1.QPModelData, qp2.QPModelData, qp3.QPModelData, qp4.QPModelData, tutorial.TutModelData, tutorial2.TutModelData, and tutoriali.TutModelData.

evaluateNonlinearJacobian()

pyconopt.ModelData.evaluateNonlinearJacobian	(		self,
			x,
			rowno,
			jacnum,
			ignerr,
			thread )

callback method for evaluating the jacobian for 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.
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.

Returns

a vector the length of jacnum that contains the jacobian values for the referenced elements.

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

Reimplemented in qp1.QPModelData, qp2.QPModelData, qp3.QPModelData, qp4.QPModelData, tutorial.TutModelData, tutorial2.TutModelData, and tutoriali.TutModelData.

endFDEvaluation()

pyconopt.ModelData.endFDEvaluation	(		self,
			ignerr )

Optional function, if defined, it will be called at the end of the function evaluation stage.

This can be used to clean up any user data generated, such as in FDEvalIni, that was used to improve the efficiency of the function and derivative evaluation.

Parameters

ignerr

a boolean to indicate whether the current point is safe or unsafe.

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