MODIFIED INCOMPLETE CHOLESKY FACTORIZATION FOR SOLVING ELECTROMAGNETIC SCATTERING PROBLEMS [PDF]
Progress In Electromagnetics Research B, 2009 In this paper, we study a class of modified incomplete Cholesky factorization preconditioners LLT with two control parameters including dropping rules. Before computing preconditioners, the modified incomplete Cholesky factorization algorithm allows to decide the sparsity of incomplete factorization preconditioners by two fillin control parameters: (1)

Fast Kernel k-means Clustering Using Incomplete Cholesky Factorization
CoRR, 2020 Kernel-based clustering algorithm can identify and capture the non-linear structure in datasets, and thereby it can achieve better performance than linear clustering. However, computing and storing the entire kernel matrix occupy so large memory that it is difficult for kernel-based clustering to deal with large-scale datasets. In this paper, we employ

Cholesky Factorization of Matrices [PDF]
, 2020 Cholesky factorization is a type of matrix factorization which is used for solving system of linear equations. In this paper, we will study the factorization of real positive definite matrices by using Cholesky factorization.

Affinification: A Fine Approximation of Deformations
Computer Graphics Forum, EarlyView.Abstract We introduce affinification, a novel method for accelerating physics‐based animation of elastic solids. During a time‐dependent simulation, our method automatically partitions the space into affine and elastic regions depending on the deformation.

Accelerating Volkov's Hybrid Implementation of Cholesky Factorization on a Fermi GPU [PDF]
, 2012 In linear algebra, Cholesky factorization is useful in solving a system of equations with a symmetric positive definite coefficient matrix. Cholesky factorization is roughly twice as fast relative to LU factorization which applies to general matrices. In

South Africa's Inflation: Monetary or Fiscal
South African Journal of Economics, Volume 94, Issue 4, December 2026.ABSTRACT Conventional macroeconomics has viewed inflation as a monetary phenomenon through the quantity theory of money. Ever‐increasing sovereign debt globally has caused concern amongst economists. These concerns follow not from the ability of governments to repay their debt, but rather the impact of sizeable debt portfolios on price levels.

How to enviromically predict breeding genotypes as if they were commercial cultivars?
Crop Science, Volume 66, Issue 5, September/October 2026.Abstract Early trial rankings may not translate into cultivar‐stage performance, especially when genotype‐by‐environment interaction changes the target response across breeding stages. This study implemented and evaluated a bi‐trait genomic–enviromic reaction‐norm framework to predict breeding genotypes “as cultivars” by combining genomic relationships,
