Dear all, 

talking about OSI 0.102.1

in the method:   const double *OsiCpxSolverInterface::getRowActivity() 
const  , shouldn't line 21: 

                   rowact_[r] = getRightHandSide()[r] + rowslack[r];

be replaced by 

                   rowact_[r] = getRightHandSide()[r] - rowslack[r];

since CPLEX treats rows as Lower than  Type ? 

Sincerely 

Stefano
