Let KK be a convex subset of a normed linear space and let R1R^1 denote the real line. We show that there are many (in the sense of Baire category) strictly convex and totally convex functions f ⁣:KR1f \colon K \to R^1. It is known that the existence of such functions is crucial in numerous optimization algorithms.
