Updating preconditioners for modified least squares problems

In this paper, we analyze how to update incomplete Cholesky preconditioners to solve least squares problems using iterative methods when the set of linear relations is updated with some new information, a new ...

Low-rank updates of balanced incomplete factorization preconditioners

Let A x = b be a large and sparse system of linear equations where A is a nonsingular matrix. An approximate solution is frequently obtained by applying preconditioned iterations. Consider...

QTL Analysis for Root Protein in a Backcross Family of Cassava Derived from Manihot esculenta ssp flabellifolia

Root protein content of elite cassava is very low, largely due to breeder’s selection for other agronomic traits mainly fresh weight yield and disease resistance. Increased protein content in the root of cassa...
