List of well-known submodular function in physics, statistics, math?

Question

Can you please share a list of well-known submodular functions (have the diminishing return property) that you know? In physics, stats, math, etc?

I am searching for a submodular function for my research problem, which is a bit too much to describe here. So simply share your knowledge about some submodular functions here would very much appreciated.

Ideally, I look for a function that is well-known and has been used often or popularly in sciences, such as entropy, etc. You can discard those simple ones, such as square-root or so.

Thanks

Answer 1

Economics is probably a good choice if you want those (diminishing returns of capital and labour in production functions)
