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. cupra born sofort verfügbare neuwagen
