AN ALGORITHM FOR THE numerical DETECTION OF SIMPLEX OVERLAP
收藏 引用
APPLIED MATHEMATICS LETTERS 1995年 第4期8卷 13-18页
作者: BRODZIK, ML Department of Mathematics and Statistics University of Pittsburgh Pittsburgh PA 15260 U.S.A.
A method is presented for testing whether or not two n-simplices in R(n) intersect, and if so, deciding whether or not the intersection has a nonempty interior. The algorithm is an application of a method by Stewart f... 详细信息

A Time-Freezing Approach for numerical Optimal Control of Nonsmooth Differential Equations With State Jumps
收藏 引用
IEEE CONTROL SYSTEMS LETTERS 2021年 第2期5卷 439-444页
作者: Nurkanovic, Armin Sartor, Tommaso Albrecht, Sebastian Diehl, Moritz Siemens Corp Technol D-81739 Munich Germany Univ Freiburg Dept Microsyst Engn IMTEK D-79110 Freiburg Germany Katholieke Univ Leuven Dept Mech Engn MECO Res Team B-3000 Leuven Belgium Univ Freiburg Dept Math D-79110 Freiburg Germany
We present a novel reformulation of nonsmooth differential equations with state jumps enabling their easier simulation and use in optimal control problems without the need for integer variables. The main idea is to in... 详细信息

METHODOLOGY AND COMPUTING IN APPLIED PROBABILITY 2008年 第2期10卷 179-198页
作者: Mercier, Sophie Univ Paris Est Lab Anal & Math Appl CNRS UMR 8050 F-77454 Marne La Vallee France
We propose new easily computable bounds for different quantities which are solutions of Markov renewal equations linked to some continuous-time semi-Markov process (SMP). The idea is to construct two new discrete-time... 详细信息
