how to change the batch.programs

[coingoldens]

Hello,

Sorry to bother you with my issue, but I don't think I've seen anyone else report the same problem as mine.
I'm still very much a neophyte when it comes to python and, by extension, anaconda.
So, I hope that perhaps my problem is actually trivial.

For example, I want to fit a function with four variables('x','m','L','MT') , but the program :

batch.programs.get_programs_array()[4]: [sqrt mul L c_x]

It is useless in my programs, how can I delete it and only keep the functions with 4 variables?

thanks
