Column()
Column ( coeffs=None, constrs=None )
Column constructor.
Arguments:
coeffs (optional): Lists the coefficients associated with the members of constrs.
constrs (optional): Constraint or constraints that participate in expression. If constrs is a list, then coeffs must contain a list of the same length. If constrs is a single constraint, then coeffs must be a scalar.
Return value:
An expression object.
Example usage:
constrs = model.getConstrs() c = Column() c.addTerms(3.0, constrs[0]) model.addVar(vtype=GRB.BINARY, obj=1.0, column=c) model.addVar(vtype=GRB.INTEGER, column=Column(3.0, constrs[0])) model.addVar(obj=3.0, column=Column([1.0, 2.0], constrs[1:3]))
