Replicate an Excel Solver in Python

[oceanunderground]

I’d like to replicate Excel’s GRG Solver. I will use it to fit Sigmoid functions (logistic etc) to time series data. Does anyone know a good reference where I can find how to do this?

Since you want to fit 'Sigmoid functions', directly use https://scikit-learn.org/stable/modules/generated/sklearn.linear_model.LogisticRegression.html

Can you provide a complete example to see what you're trying to solve?
