How to add more input arguments to objection function

[David King]

Is it possible to add additional arguments. For example, adding default arguments as the following example works: 

      def objective(args, idx = 10)

but the following example would show positional error: 

      def objective(args)

Thanks

One option is to use hp.choice to introduction two cases, e.g. 1st case it hyperparameter, 2nd case contain arguments with fixed value. Just wondering if that will slow down the optimization process
