Hi,

I encountered a new problem. When I do MGE training, an error occurred at iteration 1:

ERROR [+9999] Cholesky_Factorization: (253,253)-th element of W'*U(-1)*W is negative.

The iteration bound of HMgeTool is set to be "-i 0 5". When I used "-i 0 5", This error didn't occur.

And another question is, why the cmps are processed orderedless when the iteration number is larger then 0?

Thanks in advance,

Na Xingyu
