| Purpose | |||||||
| |||||||
|
Get the current objective function value. | ||||||
| |||||||
| Synopsis | |||||||
| |||||||
|
int QSget_objval (QSprob p, double *value) | ||||||
| |||||||
| Arguments | |||||||
|
| ||||||
| |||||||
| Returns | |||||||
| |||||||
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred. Note that QSget_objval returns an error code if it is called with a specified problem that has not been solved with one of the optimization functions ( QSopt_dual or QSopt_primal) since the last time the problem was loaded or modified. | ||||||
| |||||||
| Description | |||||||
| |||||||
|
After a successful call to one of the optimization routines ( QSopt_dual or QSopt_primal), this function can be used to obtain the value of the objective function. | ||||||
| |||||||
| Example | |||||||
| |||||||
|
/* p is an initialized QSprob, a handle to an existing LP problem */
int rval;
double value;
rval = QSget_objval (p, &value);
if (rval) {
fprintf (stderr,
"Could not get objective value, error code %d\n", rval);
} else {
printf ("Objective value = %.6f\n", value);
}
