Kkt conditions for equality constraints

WebLecture 13: KKT conditions 13-5 13.4 Examples 13.4.1 Quadratic optimization with equality constraints Consider for Q 0, min x2Rn 1 2 xTQx+ cTx subject to Ax= 0 (13.24) As Q 0, the above problem is convex. By stationarity and primal feasibility, we have xis a solution if and only if Q AT A 0 x v = c 0 (13.25) for some v. WebExample: quadratic with equality constraints Consider for Q 0, min x 1 2 xTQx+cTx subject to Ax= 0 (For example, this corresponds to Newton step for the constrained problem min x f(x) subject to Ax= b) Convex problem, no inequality constraints, so by KKT conditions: xis a solution if and only if Q AT A 0 x u = c 0 for some u.

The KKT … WebFeb 27, 2024 · Strongly-active inequalities are included as linearized equality constraints in the QP, while weakly-active constraints are linearized and added as inequality constraints to the QP. This ensures that the true solution path is tracked more accurately also when the full Hessian of the optimization problem becomes non-convex.
