it was surprising to find the dE value increases 10 order after iteration 32. Could anyone please help us sort out the problem

I suggest you to explain a little bit more you system. Is that happen every runs or only in in this system?. If that the case what kind of system do you have? metal, slab, etc... Then the community can give you some suggestions.

You are spanning a range of at least 13 orders of magnitude in energy. Why do you use such tight criteria?

The minimizer doesn't find the minima within your limits, makes a big jump and searches somewhere else.

cheers,
