Alternating direction method of multiplier (ADMM) is a widely used algorithm for solving constrained optimization problems in image restoration. Among many useful features, one critical feature of the ADMM algorithm is its modular structure, which allows one to plug in any off-the-shelf image denois...

虽然我对优化不在行,但是感觉优化问题还是挺有意思的,下面是一个经典问题,即找到两个非空凸包的交集中的一点。该算法都可以追溯到1930年代的Neumann交替投影算法(alternating projections algorithm): xk+1zk+1=ΠC(zk)=ΠD(xk+1) ΠC,ΠD分别是两个集合的欧式空间投影。写成ADMM形式就是 ...
In this study, a two-stage reactive power optimization method based on the alternating direction method of multipliers (ADMM) algorithm is proposed for achieving optimal reactive power dispatch in wind farm-integrated distribution systems. Unlike existing optimal reactive power control methods, the ...
