426 APPENDIX B. PARAMETERS B.1.66 dparam.simplex abs tol piv Corresponding constant: dparam.simplex abs tol piv Description: Absolute pivot tolerance employed by the simplex optimizers. Possible Values: Any number between 1.0e-12 and +inf. Default value: 1.0e-7 B.1.67 dparam.upper obj cut Corresponding constant: dparam.upper obj cut Description: If either a primal or dual feasible solution is found proving that the optimal objective value is outside, [dparam.lower obj cut, dparam.upper obj cut], then MOSEK is terminated. Possible Values: Any number between -inf and +inf. Default value: 1.0e30 See also: • dparam.upper obj cut finite trh Objective bound. B.1.68 dparam.upper obj cut finite trh Corresponding constant: dparam.upper obj cut finite trh Description: If the upper objective cut is greater than the value of this value parameter, then the the upper objective cut dparam.upper obj cut is treated as ∞. Possible Values: Any number between -inf and +inf. Default value: 0.5e30

B.2. IPARAM: INTEGER PARAMETERS 427 B.2 iparam: Integer parameters B.2.1 iparam.alloc add qnz Corresponding constant: iparam.alloc add qnz Description: Additional number of Q non-zeros that are allocated space for when numanz exceeds maxnumqnz during addition of new Q entries. Possible Values: Any number between 0 and +inf. Default value: 5000 B.2.2 iparam.ana sol basis Corresponding constant: iparam.ana sol basis Description: Controls whether the basis matrix is analyzed in solaution analyzer. Possible values: • onoffkey.off Switch the option off. • onoffkey.on Switch the option on. Default value: onoffkey.on B.2.3 iparam.ana sol print violated Corresponding constant: iparam.ana sol print violated Description: Controls whether a list of violated constraints is printed when calling Task.analyzesolution. All constraints violated by more than the value set by the parameter dparam.ana sol infeas tol will be printed. Possible values:
