ML_FF_CTIFOR = [real]
Default: ML_FF_CTIFOR =  

Description: This flag sets the threshold for the Bayesian error estimation on the force in the machine learning force field method.


During learning, if a newly considered structure yields a Bayesian error in the force larger than ML_FF_CTIFOR, a first principles calculation is performed, and the corresponding structure is added to the date set of structures that are used when the force field is updated. This flag is only used if ML_FF_IERR=2 or 3. The unit of ML_FF_CTIFOR is eV/Angstrom. If the tag ML_FF_LCRITERIA=.TRUE. is set, ML_FF_CTIFOR is updated.

For more details see ML_FF_ISAMPLE .
