On a Nonlinear Fast Deterministic Block Kaczmarz Method for Solving Nonlinear Equations
For solving large-scale nonlinear equations, a nonlinear fast deterministic block Kaczmarz method based on a greedy strategy is proposed. The method is adaptive and does not need to compute the pseudoinverses of submatrices. It is proved that the method will converge linearly to the nearest solution to the initial point under mild conditions. Numerical experiments are performed to illustrate that the method is efficient at least for the tested problems.
