Talk:Supermodular function

Notation
What does prim stand for on z? How do z' and z relate? —Preceding unsigned comment added by 140.123.218.105 (talk • contribs)


 * The elements z and z&prime; can be any arbitrary elements of Rk. I've changed the variables used to x and y to help clarify this. Michael Slone (talk) 17:03, 7 June 2008 (UTC)

What is R?
The real numbers (usually noted by $$\mathbb{R}$$)? A linear order? 192.114.91.228 (talk) 08:40, 23 April 2013 (UTC)

Merge with submodular function and generalize to lattices
I suggest merging this article with submodular function, since a function is supermodular iff its negative is submodular.

Furthermore, I propose generalizing the definition to lattices, of which the lattice of subsets is a special case. 50.221.225.231 (talk) 16:37, 16 September 2023 (UTC)
