发帖数: 165 | 1 a dll written in C/C++, used to run well for over a year on 2008 R server
platform. Suddenly begin to produce -1.#IND00 and 1.#INF00 . And those error
is not reproducible, the same run running at different time will have #IND
and #INF error in different place.
Any suggestion what might be wrong? |

请问这是因为算法不收敛造成的吗？如果发散的话怎么也该给个很大的数才对吧？ |

which kind of "边际条件"?
if run on different machine, no error. run on that machine, the same run
will fail (setup file, parameter file, model version etc are all the same |
