energy minimization parameters

Hello users,

I’d like to ask a question about energy minimization issue which I cannot find exact solution of my problem in the archieve. What is the selection criteria of etol, ftol, maxiter and maxeval? I realized ones using default values of manual but as much as I understand they can affect the results or are they arbitrary?

I thought about analyzing force and energy output at first but even so how can I constrict these values? So is there anyone who can give a suggestion about scientific decision of those parameters especially for energy and force restrictions(etol and ftol)?
