Web1 Mar 2024 · generalized trust region subproblem (GTRS) since it contains the trust region subproblem (TRS), when B = I is the identity matrix, b = 0 and c = −1, as a 5 special case. Our study is inspired by the following results obtained by Mor´e [10]: i) a vector x∗ ∈ Rn is a global optimizer of the GTRS (1) if and only if g(x∗) ≤ 0 WebA generalized trust region subproblem (GTRS), in which a general quadratic constraint appears instead of the norm constraint, is also known to be tractable. Mor e formulated in [19] necessary and su cient conditions for global minimizers of a GTRS. This result was utilized by Beck, Stoica and Li [3] in solving a
