On convergence rate estimation for gradient projection method
The author studies the dependency of convergence estimates for the gradient projection method on the behavior of the objective function in a neighborhood of the solution of the problem. In section 1 preliminaries and the definition of conditional sharpness minimum are given. In section 2 the convergence of the gradient projection method to a minimum with various degrees of sharpness is considered. A theorem on finite convergence of the gradient projection method is proved. In section 3 three theorems considering the rate of convergence are proved.
