Combination Sum //代码1public class Solution {public List<List<Integer>> combinationSum(int[] candidates, int target) {List<List<Integer>> result = new ArrayList<List<Integer>>();if(candidates.length
题目连接:Leetcode 039 Combination Sum 解题思路:隐式图搜索,状态包括当前使用到的数值下标(对应值一定使用过),和剩余的和。每次枚举当前下标往后的一个数,并枚举使用它的个数,对每个合理状态插入队列。而当剩余的和为零时,记录答案。 class Solution {public:vector<vector<int>> combinationSum(vector<int>

双耦合判决引导 1、定义两个不同平滑参数的DD 其中,a >> b. 2、双耦合判决引导 其中, 论文中,a=0.99, b=0.6 在网上看到的一个关于DD优化的论文,文章据说可以优化音乐噪声和失真度。还没实际实现测试,攻关项目结束后跑个实际效果试试在把结果放这里。 参考文献 【1】A Priori SNR Estimator Based on a Convex Combinat
