Has anyone used the Forrester function?[D]

Hey guys,

I came across the Forrester function recently while studying mathematics, and I started wondering if there’s more to it than just being a mathematical function.

I have a feeling I’ve seen it come up in machine learning or optimization, but I’m not really sure what it’s actually used for.

Does anyone here have experience with it? Is it mostly something people use to test/benchmark ML or optimization methods, or is it actually useful for solving real-world problems?

And since I’m studying Economics and Data Science, I’m also curious if it has any applications in economics, econometrics, forecasting, or economic modeling.

Would love to hear from someone who has actually encountered it in practice. Even a simple explanation would help 😄
