Description: 虽然说生成随机数大家都知道.但是要生成指定长度.指定字符组合.随机率在1/2000000.就难了.这是我在做充值卡时写的用来生成充值时写的随机数生成器.也是原创吧.在网上找了一堆不满意,只好自己写了.-generated random number is known to all. However, to generate a specified length. Designated character portfolio. Random rates in the 1/2 million. Very difficult. This is my doing prepaid card was used to generate the recharging time to write the random number generator. It is also original. On the Internet to find a heap of dissatisfied, but his writing.

Description: 改进遗传算法－郭涛算法做最优化问题很管用,算法的基本思想是
先任意产生n个随机数，然后从n个数里随机选择m个数，再有这m个
数合成一个新数，将这个新数同n个数中间适应值函数值的最差的比较，
如果好的话就取代最差的那个，如果它比最好的还要好的话，则把最好的
也取代。如果比最差的坏，则重新合成一个新数。依次循环下去。
程序的奇妙之处是GA_crossover()函数，产生的新数确实比较好，看看
那位大侠能改进一下，产生比这跟好的数。-improved genetic algorithm- Guo Tao done optimization algorithm is very effective, and the algorithm is the first basic idea arbitrary n generated random number and then the number li n m randomly selected number, and this number m of a new synthesis of the new middle with n number fitness function of the worst by comparison, if a good case to replace the worst, um, if it even than the best, then ruled the best have replaced. If worse than the worst, a de novo synthesis of new. Followed by the cycle continues. The magic of procedures is GA_crossover () function, the new really good to see heroes who can be improved upon, it generated more than a few with a good.

Description: Distribution generator
Here is a simple generator which can build some distributions with given properties.
Distributions generator (compile with -lm)
Typical use might be:
./distributions -u -m 1 -M 10 -n 100 -s 500
Generates a distribution of 100 uniform random numbers between 1 and 10, such that the sum of numbers is 500.
./distributions -p -2.2 -m 1 -M 100 -n 200 -s 500
