ML_FF_LCRITERIA = [logical]
Default: ML_FF_LCRITERIA = .TRUE. 

Description: Decides whether the threshold (ML_FF_CTIFOR) is updated in the machine learning force field methods.


This flag is only used if Bayesian error estimation is switched on (ML_FF_IERR=2 or 3). Generally it is recommended to automatically update the criteria ML_FF_CTIFOR during machine learning. Details on whether the update is performed are controlled by ML_FF_CSLOPE, ML_FF_CSIG and ML_FF_MHIS.

ML_FF_CTIFOR is set to the average of the Bayesian errors of the forces stored in the history. The number of entries in the history are controlled by ML_FF_MHIS. To avoid that noise data or an abrupt jump in the Bayesian error causes issues, the standard error of the history most be below the threshold ML_FF_CSIG.
