Default value of "mixing_beta"

Here the default value of "mixing_beta" is set to -10, which should not be a reasonable value.
Are there any other considerations for such a default?

I agree, it should be improved.

-10 actually is a dummy value for telling the abacus to auto-set mixing_beta.

There are two methods in the code of ABACUS to set default value of input parameters

One is like the case of mixing_beta, which uses a dummy value.
The other one is the case of symmetry, which uses a string of default and std:stoi method

Here is a discussion about these two methods

OK! Thank you for your reply.
