PKU_算法_分类

主流算法:

1.搜索 //回溯

2.DP(动态规划) 

3.贪心 

4.图论 //Dijkstra、最小生成树、网络流

5.数论 //解模线性方程

6.计算几何 //凸壳、同等安置矩形的并的面积与周长

7.组合数学 //Polya定理

8.模拟 

9.数据结构 //并查集、堆

10.博弈论 

//表示举例

 

非主流算法:

1.送分题 

2.构造 

3.高精度 

4.几何 

5.排序 

6.日期/时间处理 (这类题目相当多的)

7.数学方法 

8.枚举 

9.递推 

10.递归 

11.分治 

 

 

说明:

  显然“送分题”不是一种算法。但是ACM竞赛中经常有一些很简单很简单的题目,具体涉及内容繁杂,难以归类,干脆就管他们叫送分题。

  几何不同于计算几何,计算几何或者叫S计算几何,以Shamos1975年发表的一篇论文为诞生标志。其实两者有很大的不同。
