void Bonmin::CouenneInterface::extractLinearRelaxation ( OsiSolverInterface &  si,
CouenneCutGenerator couenneCg,
bool  getObj = 1,
bool  solveNlp = 1 
) [virtual]

Extract a linear relaxation of the MINLP.

Solve the continuous relaxation and takes first-order outer-approximation constraints at the optimum. The put everything in an OsiSolverInterface.
