解决 MINLP 问题(GAMS 24.4.1/SCIP 版本 3.1 (020d055))后出现以下错误:

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。有没有办法避免这种情况?如果需要,我可以上传 GAMS 文件。

谢谢你。

您可以设置选项 gams/resolvenlp = FALSE 以避免在最后解决子 NLP。但是,如果能够深入了解 GAMS 模型文件,那也将是一件好事。
