Abstract: | In this paper, a projected gradient trust region algorithm for solving nonlinear equality systems with convex constraints
is considered. The global convergence results are developed in a very general setting of computing trial directions by this
method combining with the line search technique. Close to the solution set this method is locally Q-superlinearly convergent
under an error bound assumption which is much weaker than the standard nonsingularity condition. |
