A class of pseudoinverse-free greedy block nonlinear Kaczmarz methods for nonlinear systems of equations
Ying Lv, Wendi Bao, Lili Xing +1
In this paper, we construct a class of nonlinear greedy average block Kaczmarz methods to solve nonlinear problems without computing the Moore-Penrose pseudoinverse. This kind of m…
