现在要用GA算个函数的极值，用matlab试了试，发现真是慢
不知道用 C的会不会快点？
从网上下了些源代码，发现看起来真是庞大。。。。有没有做过这方面的铜锈给点建议
1. 用c编的GA会不会快点?
2. 推荐一下哪里的c的源代码好用点?

if you use matlab as an interpreter, C is much faster for sure. But if you can
use some compiled module in Matlab, it could be even faster than C.

i guess it depends on how you write your code in C.

many code in the internet has been written very well.

i know many module in matlab are written in c or fortran. So how could
they be faster than the original version.

would you tell me what is the diffrence between interprter and compiled module?
I just use some M. files, interpreter means 从C里面调用matlab?
thanks

sigh, the problem is so many code in internet about GA, seems I have to try
to understand them first, so many!【在 wwww (water) 的大作中提到: 】
