如何解决此CPLEX异常？
[英]How to solve this CPLEX exception?
问题描述
I have made a program to solve a (non trivial) optimization problem with CPLEX. 
我编写了一个程序来解决CPLEX的（非平凡的）优化问题。 I have reviewed the code and the modelisation several times and I don't see problems. 我已经多次审查了代码和建模，但没有发现问题。 However, when I launch the process, the following error message appears : 但是，当我启动该过程时，会出现以下错误消息：
Concert exception 'ilog.cplex.CpxException: CPLEX Error 5002: Q in ''q1'' is not positive semi-definite
Does it imply that there is a mistake in my stuff or is there a trick to avoid this ? 是暗示我的东西有错误还是有技巧避免这种情况？
Thanks in advance ! 提前致谢 ！
