 # Objective Scaling
-Sometimes the model will be built into an ill form if some objective terms are quite large or small. To alleviate this problem, we could add a scaling factor to scale the objective function during solving while leaving all other expressions untouched. The default ```ObjScale``` is set to 1 which has no effect on objective. If you want to scale the objective, you can set the ```ObjScale``` to an appropriate value in the ```genx_settings.yml```. The objective function will be multiplied by the ```ObjScale``` value during the solving process.
