Linear Programming Algorithms Using Least-Squares Method
To my beloved wife, Yuijn iii ACKNOWLEDGEMENTS First, I want to thank my wife Yujin for her enduring patience and loving support during my study. She has been always there for me from the very beginning to this very end. She has been at the core of my motivation even when I was doubting if could finish this program. I also have to mention my beloved children, Lynn and Olivia, who have been an e...
متن کاملSelf-Calibration via Linear Least Squares
Whenever we use devices to take measurements, calibration is indispensable. While the purpose of calibration is to reduce bias and uncertainty in the measurements, it can be quite difficult, expensive and sometimes even impossible to implement. We study a challenging problem called self-calibration, i.e., the task of designing an algorithm for devices so that the algorithm is able to perform ca...
متن کاملFast and Efficient Linear Programming and Linear Least-squares Computationst
We present a new parallel algorithm for computing a least-squares solution to a sparse overdetermined system of linear equations Ax = b such that the m x n matrix A is sparse and the graph, G = (V, E), of the matrix has an s(m +n)-separator family, i.e. either IV[ <n o for a fixed constant n 0 or, by deleting a separator subset S of vertices of size <~s(m +n), G can be partitioned into two disc...
متن کاملLinear Least Squares Problems
A fundamental task in scientific computing is to estimate parameters in a mathematical model from collected data which are subject to errors. The influence of the errors can be reduced by using a greater number of data than the number of unknowns. If the model is linear, the resulting problem is then to “solve” an in general inconsistent linear system Ax = b, where A ∈ Rm×n and m ≥ n. In other ...
متن کاملNon-linear Least Squares
Using measured radial velocity data of nine double lined spectroscopic binary systems NSV 223, AB And, V2082 Cyg, HS Her, V918 Her, BV Dra, BW Dra, V2357 Oph, and YZ Cas, we find corresponding orbital and spectroscopic elements via the method introduced by Karami & Mohebi (2007a) and Karami & Teimoorinia (2007). Our numerical results are in good agreement with those obtained by others using mor...
