WebProof of strong duality under Slater’s condition and primal convexity can be found in 5.3.2. of [2]. Example of a Slater point: min x f 0(x) s.t. x2 1 5x+ 1 2 Note that since second constraint is a ne, we only need to check the rst condition. Since X, R, 9xs.t. x2 <1. Hence Slater’s condition holds and Web1 Strong duality: Slater’s condition It turns out that in most of the applications of semide nite programming to real world, strong duality holds. Hence the optimal value of primal is same as optimal value of dual. Strong duality can be obtained by verifying Slater condition. Speci cally, if the semide nite program satis es Slater conditions ... WebIn mathematics, Slater's condition (or Slater condition) is a sufficient condition for strong duality to hold for a convex optimization problem, named after Morton L. Slater.
