submodular optimization. For example, the set
cover problem is a
special case of
submodular optimization,
since the set

- {\displaystyle x} and y {\displaystyle y} . If −f is
supermodular then f is
called submodular, and if the
inequality is
changed to an

- In the
theory of
combinatorial optimization,
submodular flow is a
general class of
optimization problems that
includes as
special cases the minimum-cost...
- non-negative,
every submodular function is subadditive. However,
there are non-negative
subadditive functions that are not
submodular. For example, ****ume...
