老板想给TSP找更快或更好的近似算法,所以最近学了下 Primal-Dual Method (原始-对偶方法) 这个近似算法的大锤。原因是TSP目前最好的 3/2-approximation 来自于先找 MST (最小生成树 ), 再在 MST 中所有奇度数的顶点上找 Min Cost Perfect Matching (最小值完美匹配) 从而得到一个 Hamiltonian Cycle (哈密...
Primal-dual method of multipliers是一种基于拉格朗日对偶性的优化方法。它通过将原始问题转化为一个等价的无约束优化问题,然后利用内点法来求解该无约束优化问题。该方法的基本思想是引入拉格朗日乘子,将原问题转化为一个扩展拉格朗日函数,并通过对该函数进行优化来求解原问题。 二、应用领域: Primal-dual method of mu...
2) original dual method 原始对偶法 1. Commonly in additional to simplex method and dual simplex method,another original dual method can solve the liner programming. 解线性规划问题除常见的单纯形法和对偶单纯形法外,还有一种原始对偶法。3) primal-dual interior point method 原始-对偶内点法...
Natural Policy Gradient Primal-Dual Method for Constrained Markov Decision Processes Dongsheng Ding ECE University of Southern California NIPS20 备注: 理论文章,对于CMDP的primal-dual方法,作者采用自然梯度法来更新原问题(参数theta),用投影的次梯度法来更新对偶变量(参数为lambda),在策略参数化使用softmax形式的...
1) primal-dual method 原-对偶方法2) dual method 对偶方法 1. In this paper,by taking the stationary field for example,equal calculation of polari- sation medium additional field is studied,then dual methods between electric field and magnetic field are described. 研究了极化电介质附加场的等效...
The basic idea of this algorithm is to incorporate a multi-step acceleration scheme into the primal-dual method without smoothing the objective function. For deterministic SPP, the APD method achieves the same optimal rate of convergence as Nesterov's smoothing technique. Our stochastic APD method ...
primal-dual-based method -回复 什么是原始对偶法方法(primal-dual-based method)? 原始对偶法方法是一种优化算法,用于求解具有原始对偶结构的优化问题。在这种方法中,优化问题被分解成原始问题和对偶问题,并通过迭代地求解它们之间的对偶性关系来获得最优解。 原始对偶法方法的一般框架如下: 1.确定原始问题:将给定...
