F0(x⋆) = f0((1/k) Xk i=1 Qix) ≤ (1/k) Xk i=1 f0(Qix) = f0(x⋆) Therefore x⋆ is also optimal (d) Suppose x⋆ is a minimizer of f Let x = (1/n!) P P Px ⋆, where the sum is over all permutations Since x is invariant under any permutation, we conclude that x = α1 for some α ∈ R By Jensen’s inequality we have f(x) ≤ (1/n!) X P.
