Quadratic Functions, Optimization, and Quadratic Forms
ocw.mit.eduA quadratic optimization problem is an optimization problem of the form: (QP) : minimize f (x):=1 xT Qx + c xT 2 s.t. x ∈ n. Problems of the form QP are natural models that arise in a variety of settings. For example, consider the problem of approximately solving an over-determined linear system Ax = b, where A has more rows than
