When specified, the solution process stops if the solver can guarantee that the current best solution is within the value of suffix optca of the global optimum. This is only valid for mixed integer programming models including mixed integer quadratic problems. When specified the suffix .optca overrides the option MIP_Absolute_Optimality_Tolerance.


The value of the .optca suffix is numeric.


  • The suffix .optca is initialized to NA. AIMMS considers it specified when its value is not equal to NA.
