Witryna您收到(message from solver=Ipopt 3.11.1\x3a Converged to a locally infeasible point.Problem may be infeasible.)的消息并不表示该问题必然是不可行的。非线性求解器通常会为您提供一个局部最优值,而到达解决方案的路径是找到“更好的”局部最优值的非常重要的部分。 Witryna推荐律师服务: 若未解决您的问题,请您详细描述您的问题,通过百度律临进行免费专业咨询

Witryna7 kwi 2014 · As I encountered this issue too and because this is the first post to show up in my Google search, I want to thank Jeff A Wrightfor the answer. I use a WatchGuard Firewall connected to my computer by wired Ethernet. Witryna1 wrz 2009 · 提示是说没有在局部找到可行解 因为你的模型是非线性的,而lingo默认求的是局部最优可行解,它在线性的情况下局部最优解就是全局最优 而在非线性的情况下,可能就不同了,所以需要在longo-options-global solver里选择use global solver. 本回答被提问者采纳. 3. 评论. dfg25aw ...
