Question

解决MINLP问题后我遇到以下错误（GAMS 24.4.1 / SCIP 3.1（020d055））：

Checking feasibility of solution #00 with reported objective value -1.000000970918791e-09.
This is Ipopt version 3.11, running with linear solver ma27.

发生这种情况后，我无法检索解决方案。有办法避免这种情况吗？如果需要，我可以上传GAMS文件。

谢谢。

您可以设置选项gams / resolvenlp = FALSE以避免在最后解析子NLP。但是，如果能够仔细观察GAMS模型文件，那也很高兴。

IPOPT内存不足
