The randomized circumcentered-reflection iteration method for solving consistent linear equations

Abstract: After randomly reflecting on two hyperplanes, a new iteration method is established by making use of the circumceter of the reflective points from the viewpoint of geometry. The linear combination could be non-convex when the angle between the hyperplances is small. Theoretical analysis show that the proposed method converges and the convergence rate in expectation is also addressed in detail. The relation between our method and block Kaczmarz method is well discussed. Numerical experiments further verify that… Show more
