problems. For example, suppose that the constraint g (x; y) = k is a smooth closed curve parameterized by r (t) = x (t) ; y (t) on [a; b] ; and suppose that f (x; y) is di¤erentiable at each point onh the Then …nding the extrema of ...
EXAMPLE 3 Find the point(s) on the curve y=1:5,x2 closest to the origin both visually and via the Lagrange Multiplier method. Solution: If we let f(x;y) be the square of the distance from a point (x;y) to the origin (0;0) ; then our constrained optimization ...

For this problem we derive a generalized multiplier rule as a necessary optimality condition and we show under which assumptions this multiplier rule is also sufficient for optimality. The results are also applied to multiobjective optimization problems....

problems for example, solving the SDP maximize 1Tν subject to W + diag(ν) 0 gives a lower bound for the two-way partitioning problem on page 5–7 strong duality: d= p does not hold in general (usually) holds for convex problems conditions that guarantee strong duality in convex ...
To overcome the scalability issue, we should use the first-order information only and fully harness the special prop- erties of this class of convex optimization problems. For example, it has been recently shown that the (first-order) iterative thresholding (IT) algorithms can be very e...
