粒子群优化算法是一种基于种群的随机优化算法…
Particle swarm optimization (PSO) is a population based stochastic optimization technique developed by Dr. Eberhart and Dr. Kennedy in 1995, inspired by social behavior of bird flocking or fish schooling. Each particle keeps track of its coordinates in the problem space which are associated with the best solution (fitness) it has achieved so far. (The fitness value is also stored.)
This value is called pbest. Another "best" value that is tracked by the particle swarm optimizer is the best value, obtained so far by any particle in the neighbors of the particle. This location is called lbest. when a particle takes all the population as its topological neighbors, the best value is a global best and is called gbest. Following is the steps of PSO:

ACM代码总结
经过了一段时间的努力,我再Pku上也算是有了一个阶段性的总结拉,下面是我就这段时间搞ACM来的一些代码的总结,具体的一些题目类型的总结看本Blog的相关文章。
huicpc26 ACM_PKU 代码总结
1、DP(动态规划)
/*1080-HumanGeneFunctions.cpp*/
观察题目给出的一个最优解:
AGTGATG
-GTTA-G
将其从某一处切开,如果左边部分的分值不是最大,那么将其进行调整,使其分值变大,
则整个解分值变大,与已知的最优矛盾。所以左边部分的分值必是最大。
同理,右边也是。可见满足最优子结构的性质。考虑使用DP:
设两个DNA序列分别为s1,s2,长度分别为len1,len2,score为分值表。
