set_mip_gapSpecifies the MIP gap value. void set_mip_gap(lprec *lp, unsigned char absolute, REAL mip_gap); Return Value set_mip_gap has no return value. Parameters lp Pointer to previously created lp model. See return value of make_lp, read_lp, read_LP, read_mps, read_freemps, read_MPS, read_freeMPS, read_XLI absolute If TRUE then the absolute MIP gap is set, else the relative MIP gap mip_gap The MIP gap. Remarks The set_mip_gap function sets the MIP gap that specifies a tolerance for
the branch and bound algorithm. This tolerance is the difference between the
best-found solution yet and the current solution. If the difference is smaller
than this tolerance then the solution (and all the sub-solutions) is rejected.
This can result in faster solving times, but results in a solution which is not
the perfect solution. So be careful with this tolerance. Example
