交替方向乘子法(Alternating Direction Multiplier Method,ADMM)

交替方向乘子法(Alternating Direction Multiplier Method,ADMM)是一种求解具有可分结构的凸优化问题的重要方法,其最早由Gabay和Mercier于1967年提出。ADMM是结合对偶上升法的可分离特性以及ALM松弛收敛条件,所形成的一种改进方法[5],该算法在大规模数据分析处理领域因处理速度快,收敛性

[LeetCode] 1129. Shortest Path with Alternating Colors

Consider a directed graph, with nodes labelled 0, 1, ..., n-1.  In this graph, each edge is either red or blue, and there could be self-edges or parallel edges. Each [i, j] in red_edges denotes a red directed edge from node i to node j.  Similarly,

[Swift]LeetCode693. 交替位二进制数 | Binary Number with Alternating Bits

Given a positive integer, check whether it has alternating bits: namely, if two adjacent bits will always have different values. Example 1: Input: 5Output: TrueExplanation:The binary representation of 5 is: 101  Example 2: Input: 7Output: FalseExplanation

LeetCode 693 Binary Number with Alternating Bits 解题报告

题目要求 Given a positive integer, check whether it has alternating bits: namely, if two adjacent bits will always have different values. 题目分析及思路 给定一个正整数,判断它的二进制形式是否是01交替出现。如果是则返回True,否则返回False。可以先获得该数的二进制形式
