These problems are often intrinsically difficult and unsolved even if the code length is relatively small. With the motivation to improve lower bounds on the sizes of constant weight codes and asymmetric codes,
LeetCode122. 买卖股票的最佳时机 II(动态规划、贪心算法) 题目: 贪心算法 贪心算法原理 原理链接 动态规划 贪心算法 贪心算法 什么是贪心算法 1、与动态规划算法先死,贪心算法多用来解决优化问题。 2、在动态规划中,递归属性是用于将实例划分为较小的实例。 3、贪心算法只考虑当前步骤的最优解,不保证全局的...
This paper presents a survey on Greedy Algorithm. This discussion is centered on overview of huffman code, huffman algorithm and applications of greedy algorithm. A greedy algorithm is an algorithm that follows the problem solving heuristic of making the locally optimal choice at each stage with ...
The above code is an implementation of the Greedy algorithm for solving the Activity Selection Problem. ThePrintMaxActivitiesfunction takes as input two arrayssandfof lengthn, representing the start and finish times ofnactivities, respectively. The goal is to select the maximum number of activities t...

Jump Game(https://leetcode.com/problems/jump-game/) 给定非负整数列表,从0位置起按照所在位置的p值往前跳p个位置,问是否能跳出列表长度。 从第0位置开始,我们p0个“下个位置“可以选,那么选哪个呢?贪心地选,从”下个位置“能得到的信息也就仅仅是”下个位置“后还能跳多远。
Problem2 Partition Labels (https://leetcode.com/problems/partition-labels/) A string S of lowercase letters is given. We want to partition this string into as many parts as possible so that each letter appears in at most one part, and return a list of integers representing the size of th...
We started by understanding the problem statement and how a greedy algorithm can solve these problems. We went on to learn a little bit about greedy algorithms, what these are and how they work. After that, we discussed two different approaches to solve this problem. The first one was brute...
A zero-error code of block length n for a DMC is defined by a set of mutually orthogonal input words (Körner and Orlitsky 1998; Cover and Thomas 2006). Furthermore, an independent set I of the characteristic graph \(G(W^n)\) corresponds to the zero-error code for \(W^n\) ...
