The algorithm, based on the block form of Gaussian elimination, consists of four steps: (1) LU decomposition A rr = L rr · U rr; (2) inversion ( L rr) 1, ( U rr) 1; (3) multiplications L pr = A pr · ( U rr) 1 U rq = ( L rr) 1 · A rq; and (4) update A ...
LU分解In this paper, a new digital watermarking algorithm based on LU decomposition of matrix is proposed. In order to apply LU decomposition, the corresponding nonnegative matrix of the image is transformed into G-diagonally dominant matrix. In the course of embedding digital watermarking, the ...
A decomposition algorithm based on proximal bundle-type method with inexact data is presented for minimizing an unconstrained nonsmooth convex function f. At each iteration, only the approximate evaluation of f and its approximate subgradients are required which make the algorithm easier to implement. ...
Matrix inversion is a fundamental technique in machine learning, but the .NET Framework doesn't seem to have a matrix inversion method. James McCaffrey remedies this with a method that uses an algorithm called Crout's LU decomposition.

Given the favorable scaling, the cost of the general purpose quantum inverse iteration algorithm can be small for future large scale quantum devices. However, generally there is no simple procedure to perform c-U operation, and it requires decomposition into a set of universal gates or multi-laye...
19 make a policy decomposition technology based on an ant colony algorithm, which decomposes a policy set into multiple sub-policies, so as to reduce the cost of policy deployment. Lischka et al.20 put forward a distributed method, which analyzes the architecture of XACML policies and makes ...
Murphey (2000) develops a decomposition algorithm to solve D9. In this heuristic, he solves the first stage by some heuristic algorithm, saving the first stage solution and expected second stage solution. After this he solves the second stage primal and dual formulation across all possible second...
(1) RCD (regular cell decomposition). RCD commonly pre-sets the size of the cell and uses a rectangular shape, thus dividing the environment of the mobile robot into small cells of the same shape and equal size. For the safety of the mobile robot, we also use inflation to enlarge the ...
