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...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Reevaluation of the carbon emissions embodied in global value chains based on an inter-country input-output model with multinational enterprises
跨国企业 国家间 投入产出模式 全球价值链 碳排放
2023/5/9
Multinational enterprises actively participate in global production networks. However, the current global value chain accounting framework fails to consider the emissions originating from the producti...
A global BMI algorithm based on the generalized Benders decomposition
Linear matrix inequalities Robust control Numerical Methods
2015/8/11
We present a new algorithm for the global solution of optimization problems involving bilinear matrix inequalities (BMIs). The method is based on a technique known in large-scale and global optimizati...
Univariate global optimization with multiextremal non-differentiable constraints without penalty functions
Global optimization multiextremal constraints Lipschitz functions continuous index functions
2011/9/21
Abstract: This paper proposes a new algorithm for solving constrained global optimization problems where both the objective function and constraints are one-dimensional non-differentiable multiextrema...

2011/10/8
Abstract: Finding the parameter values of differential equation models from data is an important part of the modelling process. Large models and sparse data often make the parameters very difficult to...

Abstract: In this paper is proposed a new heuristic approach belonging to the field of evolutionary Estimation of Distribution Algorithms (EDAs). EDAs builds a probability model and a set of solutions...
Blow-up phenomena and global existence for a periodic two-component Hunter-Saxton system
A periodic two-component Hunter-Saxton system blow-up scenario blow-up
2011/2/28
This paper is concerned with blow-up phenomena and global existence for a periodic two-component Hunter-Saxton system. We first derive precise blow-up scenarios for strong solutions to the system. The...

Global generation direct images of relative pluricanonical systems
2011/1/18
In this article, using the plurisubharmonic variation property of canonical measures (cf. [T7]), we prove that for an algebraic fiber space f : X −! Y ,fOX(mKX/Y ) is globally generated on the ...
A General Local-to-Global Principle for Convexity of Momentum Maps
Convexity space momentum map geodesic manifold Lokal-global-Prinzip
2010/12/6
We extend the Local-to-Global-Principle used in the proof of convexity theorems for momentum maps to not necessarily closed maps whose target space carries a convexity structure which need not be base...
A sufficiency class for global (in time) solutions to the 3D Navier-Stokes equations II
Global (in time) 3D-Navier-Stokes Equations
2010/12/7
In this paper, we simplify and extend the results of [GZ] to in-clude the case in which = R3. Let [L2(R3)]3 be the Hilbert space of square integrable functions on R3 and let H[R3]3 =: H be the comple...
