We have already seen, in the First order sufficient condition (2.1.2), one benefit of convexity in optimization: critical points of convex functions are global minimizers. In this section we extend the types of functions we consider in two important ways: (i)We do not require f to be differentiable.(ii)We allow f to take the value + ∞.
