Accessing basis information

The sample may query basis information from the solution, if basis information is available.

After the sample solves the model by calling the method solve, it accesses the results in the same way as in ilolpex1.cpp, with the exception of basis information for the variables. Not all optimizers compute basis information. In other words, not all solutions can be queried for basis information. In particular, basis information is not available when the model is solved by the barrier optimizer (IloCplex::Barrier) without crossover (parameter IloCplex::BarCrossAlg set to IloCplex::NoAlg ).
