WebSDP Relaxations: Primal Side The original problem is: minimize xTQx subject to x2 i= 1 Let X:= xxT. Then xTQx= traceQxxT= traceQX Therefore, X”0, has rank one, and Xii= x2 i= 1. Conversely, any matrix Xwith X”0; Xii= 1; rankX= 1 necessarily has … Weboptimal solution of an SDP lifting of the original binary quadratic program. The reformulated quadratic program then has a convex quadratic objective function and the tightest … WebConic Linear Optimization and Appl. MS&E314 Lecture Note #06 10 Equivalence Result X∗ is an optimal solution matrix to SDP if and only if there exist a feasible dual variables (y∗ 1,y ∗ 2) such that S∗ = y∗ 1 I1:n +y ∗ 2 I n+1 −Q 0 S∗ •X∗ =0. Observation: zSDP ≥z∗. Theorem 1 The SDP relaxation is exact for (BQP), meaning zSDP = z∗. Moreover, there is a rank … simplify 5 1/3
