Now, the objective function is a parameter of the model. How can i specify a parametric objective function for the model? I tried using a macro variable, but i get an error ...<BR /> <BR /> Any tips?<BR /> <BR /> Many thanks Fri, 20 Jun 2008 14:35:58 GMT https://communities.sas.com/t5/Mathematical-Optimization/Parametric-objective-function/m-p/26954#M316 deleted_user 2008-06-20T14:35:58Z https://communities.sas.com/t5/Mathematical-Optimization/Parametric-objective-function/m-p/26955#M317 Please post the code snippet (and error log) that is not working as expected.
