420 APPENDIX B. PARAMETERS B.1.48 dparam.mio rel gap const Corresponding constant: dparam.mio rel gap const Description: This value is used to compute the relative gap for the solution to an integer optimization problem. Possible Values: Any number between 1.0e-15 and +inf. Default value: 1.0e-10 B.1.49 dparam.mio tol abs gap Corresponding constant: dparam.mio tol abs gap Description: Absolute optimality tolerance employed by the mixed-integer optimizer. Possible Values: Any number between 0.0 and +inf. Default value: 0.0 B.1.50 dparam.mio tol abs relax int Corresponding constant: dparam.mio tol abs relax int Description: Absolute relaxation tolerance of the integer constraints. I.e. min(|x| − ⌊x⌋, ⌈x⌉ − |x|) is less than the tolerance then the integer restrictions assumed to be satisfied. Possible Values: Any number between 1e-9 and +inf. Default value: 1.0e-5

B.1. DPARAM: DOUBLE PARAMETERS 421 B.1.51 dparam.mio tol feas Corresponding constant: dparam.mio tol feas Description: Feasibility tolerance for mixed integer solver. Any solution with maximum infeasibility below this value will be considered feasible. Possible Values: Any number between 0.0 and +inf. Default value: 1.0e-7 B.1.52 dparam.mio tol rel dual bound improvement Corresponding constant: dparam.mio tol rel dual bound improvement Description: If the relative improvement of the dual bound is smaller than this value, the solver will terminate the root cut generation. A value of 0.0 means that the value is selected automatically. Possible Values: Any number between 0.0 and 1.0. Default value: 0.0 B.1.53 dparam.mio tol rel gap Corresponding constant: dparam.mio tol rel gap Description: Relative optimality tolerance employed by the mixed-integer optimizer. Possible Values: Any number between 0.0 and +inf. Default value: 1.0e-4
