1. Problem These two algorithm are all used to find a minimum spanning tree for a weighted undirected graph. 2.Kruskal's algorithm 2.1 Pseudocode A = ∅ foreach v ∈ G.V: MAKE-SET(v) foreach (u, v) in G.E ordered by weight(u, v), increasing: if FIND-SE…

A method is presented for finding a shortest path from a starting place to a destination place in a traffic network including one or more turn restrictions, one or more U-turns and one or more P-turns using a Dijkstra algorithm. The method as sets a…

For example we have the array like this: [, , , , , ] First step is using Counting sort for last digit, in our example is: [, , , 233] [, , , , , ] Then sort according to the last digit: [, , , , , ] Then using second last digit to the sort: [, , , ,…

A* is a best-first search, meaning that it solves problems by searching amoung all possible paths to the solution(goal) for the one that incurs the smallest cost(least distance, shortest time, etc.), and among these paths it first considers the one t…

约会配对问题 一．立即接受算法: 对于约会的配对,大家都去追自己最心仪的女生.而这个女生面对几位追求者,要立刻做个决定. 被拒绝的男生们调整一下心情,再去追求心中的 No. 2.以此类推. 这样做法有一个严重的问题:当你被你的No.1拒绝后,再去追求你的No.2的时候,你心中的No.2可能已经在第一轮中选择了其他人. 但坑爹的是,有可能你正是你心中No.2心中的No.1,但是她并不知道.所以她在第一轮中,因为没有被你追求,而屈就他人.比及你在第一轮中表白失败,再去找你的No.2 时,已然晚矣.…

The median maintenance problem is a common programming challenge presented in software engineering job interviews. In this lesson we cover an example of how this problem might be presented and what your chain of thought should be to tackle this probl…

寻找最大公约数方法 代码如下: int gcd (int a, int b) { return b ? gcd (b, a % b) : a; } 应用:求最小公倍数 代码如下: int lcm (int a, int b) { return a / gcd (a, b) * b; }…

<algorithm>是C++标准程序库中的一个头文件,定义了C++ STL标准中的基础性的算法(均为函数模板).<algorithm>定义了设计用于元素范围的函数集合.任何对象序列的范围可以通过迭代器或指针访问. std::adjacent_find:在序列中查找第一对相邻且值相等的元素: std::find: 对一个输入序列,查找第一个等于给定值的元素: std::find_end: 查找有B定义的序列在A序列中最后一次出现的位置(B可能是A的子序列): std::find_f…
