Hi,
1) the rest of the user's guide is still under construction, and if want to know how to use a specific file, just ' help **' , you can get the help info.
i dont have enough time to finish this document right now...so, sorry about that.
some tips to help you out of disorder:
(1) make a deep look in to your project
(2) make a model you need and a plan about your research work , including workflow
obj: fitness = fit(xi)
con:
f1<=0
f2 = 0
(3) have a fitness function (Max, or min )
(4) set some parameters for this fitness
2)SGA_FITNESS_assignment_dummy.p is a missing file, you can find it in
bbs.sciei.com, I uploaded it .
3) NSGA-II is done but without test, i will have as many types as possible for the SGALAB..
i will upload it after i fixed some bugs of it..
that will be SGALAB1003Beta5, i think.
thanks,.

您好!
非常感谢您的回信!我对我冒昧的打扰到您,感到抱歉。
在您的指导下,我又仔细阅读了zip文件。
1) 但是在我下的文件"SGALAB_FAQ_User's Guide"中,只有前半部分,关键的后半
部分(selection,crossover,mutation,multi-objective,etc.)却没有。在初始种群
30,最大50代的情况下,我的程序要运行20多小时。我现在在算法的选择和参数的挑选
中没有一个指导思想,存在很大的盲目性和随机性,这使我在工作中处于十分被动的地
位。
所以,我想请问一下,您那里是否还存有相关的文件,能否再传一份给我。又或者
我还应该看哪些资料?
2) 对相同SGA_MO_FITNESS_function.p文件和相同的参数设置下,我运行
VEGA,MOGA,NPGA这三个算法没有碰到问题,可是在运行NSGA时系统提示:
??? Undefined command/function 'SGA_FITNESS_assignment_dummy'.
Error in ==> SGA_entry_MO_Pareto_NSGA at 243
Error in ==> SGALAB_demo_MO_NSGA at 180
[ maxfitness ,...
我现在使用的SGALAB版本是不是少了一个文件?还是NSGA算法另外在设置其他参数
?
3) 我的fitness2是象您建议的那样设置的,可是结果不好,我都不知该如何是好了。
请问您那还有其他的多目标的算法吗?例如,NSGA-II?我想再试一试其他算法,
是不是更适合我现在的问题。
以上这些都是我对我现在碰到的问题的不成熟的看法。也不知道我这些想法是否很
幼稚。
再次感激您对我的关注。
遥祝
事事顺心!
