GRBModel::addGenConstrPWL()

Add a new general constraint of type GRB_GENCONSTR_PWL to a model.

A piecewise-linear (PWL) constraint states that the relationship $y =
f(x)$ must hold between variables $x$ and $y$, where $f$ is a piecewise-linear function. The breakpoints for $f$ 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 $x$ variable.

yvar: The $y$ variable.

npts: The number of points that define the piecewise-linear function.

xpts: The $x$ values for the points that define the piecewise-linear function. Must be in non-decreasing order.

ypts: The $y$ values for the points that define the piecewise-linear function.

name (optional): Name for the new general constraint.

Return value:

New general constraint.
