GRBModel::addVar()
Add a single decision variable to a model.
| GRBVar | addVar ( | double | lb, |
| double | ub, | ||
| double | obj, | ||
| char | type, | ||
| string | name="" ) |
-
Add a variable; non-zero entries will be added later.
Arguments:
lb: Lower bound for new variable.
ub: Upper bound for new variable.
obj: Objective coefficient for new variable.
type: Variable type for new variable (GRB_CONTINUOUS, GRB_BINARY, GRB_INTEGER, GRB_SEMICONT, or GRB_SEMIINT).
name (optional): Name for new variable.
Return value:
New variable object.

| string | name="" ) |
-
Add a variable, and the associated non-zero coefficients.
Arguments:
lb: Lower bound for new variable.
ub: Upper bound for new variable.
obj: Objective coefficient for new variable.
type: Variable type for new variable (GRB_CONTINUOUS, GRB_BINARY, GRB_INTEGER, GRB_SEMICONT, or GRB_SEMIINT).
numnz: Number of constraints in which this new variable participates.
constrs: Array of constraints in which the variable participates.
coeffs: Array of coefficients for each constraint in which the variable participates.
name (optional): Name for new variable.
Return value:
New variable object.
