Detailed Description

This is a CONOPT implementation of the Pindyck model from the GAMS model library. The implementation is similar to the one in pindyck, but this time we first solve the model for 16 periods and then we gradually increase the number of periods one at a time up to 20.

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

Function Documentation

buildModel()

void PinAddModelData.buildModel ( int T, double[] xkeep, int[] xstat, int[] estat )

inline

adds variables and constraints to the model

The variables from the last solve are given the old status and the variables in the new period are given those in the last period. Similarly with the Equation status:

evaluateNonlinearTerm()

double PinAddModelData.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.

Returns

the value of the nonlinear terms.

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

evaluateNonlinearJacobian()

void PinAddModelData.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.

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