WebBearing this in mind, A convex problem is defined as an optimization of a convex function f defined over a convex domain X. If it is a constrained problem, then this also implies that a convex (constrained) problem is one in which the objective function f is convex and … WebAug 25, 2024 · A typical definition is that convex optimization asks for best value of a convex function over a convex set, and by that definition linear programs are convex optimization problems. –. Aug 25, 2024 at 12:31. Yes since the set { x / A x ≤ b } is convex since A is linear. –.
