The last of the three functions that can be used to build the model is populatebynonzero. It creates objects for the objective and the ranges without expressions, and variables without columns. The methods IloObjective::setLinearCoef, setLinearCoefs, and IloRange::setLinearCoef, setLinearCoefs are used to set individual nonzero values in the expression of the objective and the range constraints. As usual, the objective and ranges must be added to the model.
