学习任何算法,最重要的点就是掌握算法的核心本质。本文重点介绍两种经典算法(DP和GA)的差异和相同点。 二、DP和GA的异同点 2.1 、相同点: DP和GA都利用了历史信息进行求解。但是二者利用历史信息的方式有所区别。 2.2 、不同点: GA:贪心算法的每一步最优解都包含上一步的最优解,通过上一步的结果和当前的信...
The dynamic programming in chinese is “动态规划”, to be honest, this translation is imprecise, because we can’t get the real thinking of the this algorithm. The programming refers to a tabular method, according to the next context, we will understand what is a tabular method. 10月29日...
但就这么一件事,我是真的觉得这辈子都达不成。我们这学期的“算法导论”已经进入下半场了,最近在学 dynamic programming 和 greedy algorithm...上课基本上都是一个例子,就要讲两个钟头那种... 前一阵我们期中考试,大部分人都考得十分垃圾。就不光是我们这些工读学生,包括在本校就念书的硕士研究生,考得也极其...

Leetcode Tags(7)Dynamic Programming & Greedy 一、 儿女情长什么的,最影响我们闯荡江湖了。
https://stackoverflow.com/questions/14038011/dijkstras-algorithm-a-greedy-or-dynamic-programming-algorithm 此算法既应用了 贪婪策略, 也应用了 动态规划。 It's greedy because you always mark the closest vertex. It's dynamic because distances are updated using previously calculated values. ...
I feel like Kadane's algorithm is a modified version of the true dynamic programming solution of maximum subarray problem.Why do I feel so? I feel because the way to calculate the maximum subarray can be taken by: for(i=0;i<N;i++) { DP[i][A[i]]=true; for(j= -ve maximum ;j...

In this work, two of the existing algorithms for solving the Knapsack are investigated and implemented using the same programming language. The complexity of the programs and hence the algorithms were measured to determine the more efficient of the two algorithm. The result of this comparative ...
