Member Function Documentation

double * ClpLinearObjective::gradient (  const double *  solution,
double &  offset,
bool  refresh
)  [virtual]
 

Returns gradient. If Linear then solution may be NULL, also returns an offset (to be added to current one) If refresh is false then uses last solution

Implements ClpObjective.

00113 {
00114   offset=0.0;
00115   return objective_;
00116 }

ClpObjective * ClpLinearObjective::subsetClone (  int  numberColumns,
const int *  whichColumns
)  const [virtual]
 

Subset clone. Duplicates are allowed and order is as given.

Reimplemented from ClpObjective.
