matlab 非线性规划问题,我的变量有40个,很急
编程后,出现的错误是:
Warning: Large-scale (trust region) method does not currently solve this type of problem,
switching to medium-scale (line search).

请问该怎么解决啊,急

关于整数优化方面,Matlab还没有现成的工具箱可以使用,建议:
1:使用GA算法,你这个是线性优化,用GA很容易完成
2:Matlab里调用开源的算法,这是我们经常用的,开源的算法有:
lpsolve55.dll,使用这个,现在我们已经能做到2万个变量的整数优化,时间在6分钟左右
3: Matlab里调用Lindo的API,这个适合公司、院校,毕竟Lindo的API是付费的,用过lingo的人都知道,lingdo在整数优化方面,无人能及,lindo就是lingo的API
