[Cbc] Multiple Optimal Solutions

[Haroldo Gambini Santos]

Hi Satish,

Please note that CBC will exit as soon as the lower bound reaches the 
upper bound - unless you "slowdown" this event (disabling all cuts?) CBC 
will not find *all* optimal solutions. That said, you can configure how 
many solutions will be saved and access then (in C++) using:

bool CbcModel::setMaximumSolutions(int value)
const double* CbcModel::savedSolution(int which) const

Cheers,

Haroldo
