Save results of Optimize Parameter operator using macros
Hi everybody ,
I want to save result of each combination of parameter values in separate files , I know I have to use macros , but I don't know how to use it here ,
Thanks ,
Arian

Hi Arian,
you can add two Set Macro operators (one for each optimized parameter) to your inner process, and iterate the values of these macros instead of directly optimizing the parameters. Then, you can use macros for both setting the actual parameters and the filename.
Btw, you can also store the performance object in the repository with Store instead of using plain text files.
