Chapter 12 Quadratic Optimization Problems
12.1. QUADRATIC OPTIMIZATION: THE POSITIVE DEFINITE CASE 455 Thus, when the energy function P(x)ofasystemisgiven by a quadratic function P(x)= 1 2 xAx−xb, where A is symmetric positive definite, finding the global minimum of P(x) is equivalent to solving the linear system Ax = b. Sometimes, it is useful to recast a linear problem Ax = b

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
