GRBModel::addGenConstrPoly()
Add a new general constraint of type GRB_GENCONSTR_POLY to a model.
A polynomial function constraint states that the relationship
should hold between variables 
and 
.
A piecewise-linear approximation of the function is added to the model. The details of the approximation are controlled using the following four attributes (or using the parameters with the same names): FuncPieces, FuncPieceError, FuncPiecesLength, and FuncPieceRatio. For details, consult the General Constraint discussion.
| GRBGenConstr | addGenConstrPoly ( | GRBVar | xvar, |

| int | plen, | ||
| const double* | p, | ||
| std::string | name="", | ||
| std::string | options="" ) |

Arguments:
xvar: The variable.
yvar: The variable.
plen: The length of coefficient array p. If 
is the highest power term, then plen should be 
.
p: The coefficients for the polynomial function (starting with the coefficient for the highest power).
name (optional): Name for the new general constraint.
options (optional): A string that can be used to set the attributes that control the piecewise-linear approximation of this function constraint. To assign a value to an attribute, follow the attribute name with an equal sign and the desired value (with no spaces). Assignments for different attributes should be separated by spaces (e.g. "FuncPieces=-1 FuncPieceError=0.001").
Return value:
New general constraint.
