WebJul 19, 2024 · What you're looking for is the biconjugate of a function, which forms the convex envelope (hull) of a function. The conjugate of a function f: E → [ − ∞, ∞] is defines as. f ∗ ( y) = max x ∈ E y T x − f ( x), therefore the biconjugate is. f ∗ ∗ ( x) = max y ∈ E ∗ x T y − f ∗ ( y). It can be shown, for example, that the ... Web3. Combine the two hulls into overall convex hull. Part 2 is simply two recursive calls.
