Abstract
Using a short proof, we show that every set function f can be decomposed into the difference of two monotone increasing and strictly submodular functions g and h, i.e., \(f=g-h\), and every set function f can also be decomposed into the difference of two monotone increasing and strictly supermodular functions g and h, i.e., \(f=g-h\).
