Declaring the objective: IloObjective

Describes the C++ class IloObjective.

Objects of class IloObjective represent objective functions in optimization models. IloCplex may only handle models with at most one objective function, though the modeling API provided by Concert Technology does not impose this restriction. An objective function is specified by creating an instance of IloObjective . For example:

IloObjective obj(env, 
                 1*x[1] + 2*x[2] + 3*x[3],
                 IloObjective::Minimize);

defines the objective to minimize the expression 1*x[1] + 2*x[2] + 3*x[3].
