PRIMAL-DUAL ALGORITHM.A definition of the term "primal-dual algorithm" is presented. It refers to the adaptation of the simplex method that starts with a solution to the dual problem and systematically solves a restricted portion of the primal problem while improving the solution to the dual....
文本比较算法Ⅸ——Primal-Dual算法 研究文本比较算法有一段时间。看到Primal-Dual算法,作为不同的求LCS算法,介绍如下。 原文在《An almost-linear time and linear space algorithm for the longest common subsequence problem》 比较文本: A=a1a2a3……am B=b1b2b3……bn 定义集合P={(i,j)|ai=bj} 则P={...
since our algorithm moves from BFS to BFS without ever repeating a BFS, it must terminate. When it ter- minates, it either shows infeasibility of original prob- lem P or reaches optimality of P. Next: The reason that this is an interesting technique is that we will soon see that solving...

An adaptation of the simplex method that starts with a solution to the dual problem and systematically solves a restricted portion of the primal problem while improving the solution to the dual. At each step, a new restricted primal is defined and the process continues until solutions to the ...

MCPM (以及最大匹配) 的经典解法 Blossom Algorithm (带花树算法) 是基于 primal-dual method,而 primal-dual method 本身可以给很多组合优化问题尤其是网络设计问题提供近似算法。 因此在学习完之后,顺便整理了一点自己的笔记,加强理解记忆。 这里贴出来,以此监督自己,希望之后学习新工具也努力做到随时读完随时整理笔记...
Frank-Wolfe算法,也被称为条件梯度算法(Conditional Gradient Algorithm),是一种用于解决具有线性等式约束的非线性优化问题的迭代方法。该算法由Marguerite Frank和Philip Wolfe在1956年提出,因此得名Frank-Wolfe算法。它在运筹学、机器学习、统计学等领域有着广泛的应用,特别是在支持向量机(SVM)的训练中。 算法的基本思...
