对称椭圆特征值问题的一个局部化的最优预处理Newton-Schur方法
对称椭圆 特征值问题 局部化 最优预处理 Newton-Schur
2023/12/13
A locally optimal preconditioned Newton-Schur method is proposed for solving symmetric elliptic eigenvalue problems. Firstly, the Steklov-Poincaré operator is used to project the eigenvalue problem on...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：A Squared Smoothing Newton Method for Semidefinite Programming
半定规划 平方平滑 牛顿方法
2023/4/14
This paper proposes a squared smoothing Newton method via the Huber smoothing function for solving semidefinite programming problems (SDPs). We first study the fundamental properties of the matrix-val...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global and Local Convergence-Rate Analysis of an Inexact Newton Augmented Lagrangian Method for Zero-One Composite Optimization
零一复合优化 不精确 牛顿增强拉格朗日方法 收敛率分析
2023/4/14
Zero-One Composite Optimization (0/1-COP) is a prototype of nonsmooth, non- convex optimization problems and it has attracted much attention recently. Augmented Lagrangian Method (ALM) has stood out a...
Breaking Newton's Law
Breaking Newton's Law
2017/7/21
A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton’s equations of motion tell us that a moving body ke...
Review of William L.Harper,Isaac Newton's Scientific Method
Newton scientific method gravity Principia
2016/6/15
The title and dust jacket portrait of Newton eliciting the celebrated phenomenon of colors may lead one to think this is a comprehensive work on Newton’s scientific method,including his experimental w...
Absolute, true and mathematical time in Newton’s Principia
Newton absolute time absolute motion true time mathematical time
2016/6/12
I discuss the three distinctions “absolute and relative”, “true and apparent”, and “mathematical and common”, for the specific case of time in Newton’s Principia. I argue that all three distinctions a...
Newton and Spinoza:On Motion and Matter(and God,of Course)
Newton, Spinoza Clarke More Maclaurin Matter Motion
2016/5/31
This study explores several arguments against BENEDICTUS DE Spinoza Spinoza’s philosophy that were developed by Henry More, Samuel Clarke, and Colin Maclaurin. In the arguments on which I focus, More,...
Newton’s Philosophy of Time
Newton Descartes Huygens mathematical time absolute time true time
2016/5/31
In this paper I explain what Newton means with the phrase “absolute, true, and mathematical time” (Principia, Scholium to the definitions) in order to discuss some of the philosophic issues that it gi...
Einstein and Tagore,Newton and Blake,Everett and Bohr:the dual nature of reality
realism idealism quantum
2016/5/31
There are two broad opposing classes of attitudes to reality (realist vs idealist, material vs mental) with corresponding attitudes to knowledge (objective vs subjective, scientific vs romantic). I ar...
Newton on Matter and Space in De gravitatione et aequipondio fluidorum
Isaac Newton Matter Space
2016/5/30
This paper explicates the concepts of matter and space that Newton develops in De gravitatione. As I interpret Newton’s account of created substances, bodies are constructed from qualities alone, as c...
How to find all roots of complex polynomials by Newton’s method
complex polynomials Newton’s method
2015/8/26
We investigate Newton’s method to find roots of polynomials of fixed degree d, appropriately normalized: we construct a finite set of points such that, for every root of every such polynomial, at leas...

PROXIMAL NEWTON-TYPE METHODS FOR MINIMIZING COMPOSITE FUNCTIONS
convex optimization nonsmooth optimization
2015/7/3
We generalize Newton-type methods for minimizing smooth functions to handle a
sum of two convex functions: a smooth function and a nonsmooth function with a simple proximal mapping.
ON PROJECTED NEWTON BARRIER METHODS FOR LINEAR PROGRAMMING AND AN EQUIVALENCE TO KARMARKAR'S PROJECTIVE METHOD
Linear programming Karmarkar's method
2015/7/3
Interest in linear programming has been intensified recently by Karmarkar's publication in 1984
of an algorithm that is claimed to be much faster than the simplex method for practical problems.
We...
Blending Dual Time Stepping and Newton-Krylov Methods for Unsteady Flows
Blending Dual Time Stepping Newton-Krylov Methods Unsteady Flows
2015/7/3
We explore the idea of using nonlinear schemes as preconditioners in Newton-Krylov schemes for unsteady flow computations. Analysis shows that left preconditioning changes the Newton scheme in a...
