The most likely cause of this error stems from a problem in evaluating the functions within your model. Not all functions are defined for all values of their arguments. For example, @LOG( X ?1) is undefined for values of X less than or equal to 1. You should check your model for any such functions, and use the @BND function to place bounds on your variables to keep the optimizer from straying into any regions where functions become undefined.' r: D0 ?& X- S/ g
Another complicating factor can be nonlinear relations in a model. Linear models can be solved much more reliably and quickly than nonlinear models of comparable size. If possible, try to linearize your model by approximating nonlinear functions with linear ones, or by eliminating nonlinear equations.7 P3 {7 e$ J5 B( n* _* u
Another possible remedy when dealing with nonlinear models is to attempt different starting points. A starting point may be input in the model抯 INIT section. Refer to Windows Commands for more details.5 w" i4 B4 m- y6 M: C2 s1 x7 U
If this problem persists after bounding any variables that could potentially lead to a problem, removing any unnecessary nonlinearities, and attempting new starting points, please contact LINDO Systems for assistance., b$ O5 u4 k5 F( L H: V( f

出现了一个严重的问题，可能在目标函数上，比如函数定义域不符合要求，剩下的是一些其他可能的原因，就不逐字给你翻译了！作者: 风沙 时间: 2009-7-14 20:53
函数问题，变量定义付值有没有问题，有没有溢出作者: limiaoshumo 时间: 2009-7-15 21:33
呵呵 继续啊作者: hand208 时间: 2009-7-26 16:35
你运行LINGO都能出这，你太牛逼了！2 T' _8 x5 T5 G- ]) U4 u) h2 O
好好改改代码吧！肯定有重大错误！
