The fs and dfs are from the sigmoidal programming library mentioned in the link earlier and they are not in my code. I just copied one of the examples in the repo and ran it on my system. That seems to work but when I do it myself, it throws up errors.
states, actions are used to define the constraints and this issue is specific to objective function, ergo they’re unrelated I guess, however, I am open to sharing entire code if that helps in any way. b is a model parameter and is between 0 to 1. So what I basically want to do is generate a list of functions with coeff[i]*x^b where I can change b at the top, where I assign different values to different parameters of the model and it would work out. Or so I think. coeff[i] is basically the cost of the associated variable.
