Convergence Rate Analysis for Fixed-Point Iterations of Generalized Averaged Nonexpansive Operators
Yizun Lin, Yuesheng Xu
We estimate convergence rates for fixed-point iterations of a class of nonlinear operators which are partially motivated from solving convex optimization problems. We introduce the…
