mild conditions. Unlike traditional trust region method, the superlinear convergence of the method is proven under the … local error bound condition. This condition is weaker than the nondegeneracy assumption which is necessary for superlinear … convergence of traditional trust region method. We also propose an approximate algorithm for the trust region subproblem …
