我参考你的修改 现在可以运行了 而且有可行解 但相对个别目标变量取整 @gin(),但就提示无可行解了。怎么办？
我增加了 x1=m(1);x2=m(3);x3=z(1);x4=z(2);x5=z(3);x6=@cos(j(1));x7=@cos(j(2));x8=b(1);x9=b(3);
@gin(x3);@gin(x4);@gin(x5);
另外，这是一道二级斜齿轮减速器的最小体积优化问题。
谢谢再次前来指导！前面是没出现X，我的想法是题目的独立设计变量是m(1) m(3) z(1) z(2) z(3);@cos(j(1));@cos(j(2));b(1);b(3); 我想把他们9个显示集中到一块 这样看结果也就方便多了，呵呵。那我就把x1~等去掉。但我的问题依然存在：其中z是指齿数啊 应该整数化 所以在后面加一句@for(vec1(i):@gin(z(i)));吧，语法上行的通的吧 但就是没可行解。
