http://laplace.physics.ubc.ca/555B/Doc/elliptic/Elliptic2.pdf WebOur block relaxation methods look for desirable points, which are usually fixed points of point-to-set maps. They minimize, in a vast majority of the applications, a loss function or badness-of-fit function, which is often derived from some general data analysis principle such as Least Squares or Maximum Likelihood. WebIn addition, inspired by the effectiveness of block Kaczmarz algorithms for solving linear systems, we further present a block MRNK (MRBNK) algorithm based on an approximate maximum residual criterion. Based on sketch-and-project technique and sketched Newton–Raphson method, we propose the deterministic sketched Newton–Raphson … freemind mind mapping software free download
