The generalized trust region subproblem

Pong, Ting; Wolkowicz, Henry - In: Computational Optimization and Applications 58 (2014) 2, pp. 273-322

The interval bounded generalized trust region subproblem (GTRS) consists in minimizing a general quadratic objective, q <Subscript>0</Subscript>(x)→min, subject to an upper and lower bounded general quadratic constraint, ℓ≤q <Subscript>1</Subscript>(x)≤u. This means that there are no definiteness assumptions on either quadratic...</subscript></subscript>
