When specified the solution procedure stops if the solver can guarantee that the current best solution is within suffix .optcr of the global optimum. This is only valid for mixed integer programming models including mixed integer quadratic problems. The .optcr suffix controls the append mode of the file. When specified the suffix .optcr overwrites the option MIP_Relative_Optimality_Tolerance


The value of the .optcr suffix is numeric.


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