GRBModel::addGenConstrPWL()
Add a new general constraint of type GRB_GENCONSTR_PWL to a model.
A piecewise-linear (PWL) constraint states that the relationship 
must hold between variables 
and 
, where 
is a
piecewise-linear function. The breakpoints for are provided as
arguments.
Refer to the description of
piecewise-linear objectives
for details of how piecewise-linear functions are defined.
| GRBGenConstr | addGenConstrPWL ( | GRBVar | xvar, |
| GRBVar | yvar, | ||
| int | npts, | ||
| const double* | xpts, | ||
| const double* | ypts, | ||
| std::string | name="" ) |
Arguments:
xvar: The variable.
yvar: The variable.
npts: The number of points that define the piecewise-linear function.
xpts: The values for the points that define the piecewise-linear function. Must be in non-decreasing order.
ypts: The values for the points that define the piecewise-linear function.
name (optional): Name for the new general constraint.
Return value:
New general constraint.
