WebMay 7, 2024 · In a separable convex cost setting, the cost of sending xij units of flow along an arc is Cij(xij). A function is convex if f(λa+(1−λ)b)≤ λf(a)+(1−λ)f(b) for λ ∈(0,1). This means that any line connecting two points on the graph of the function lay above the function. The function Cij(x) must satisfy this, as it is convex. WebQuestion: 5.
