ML_CX = [integer]
Default: ML_CX = 0.0 

Description: The parameter determines how the threshold (ML_CTIFOR) is updated within the machine learning force field methods.


If ML_ICRITERIA>0, ML_CTIFOR is set to the average of the Bayesian errors of the forces stored in history (see ML_ICRITERIA). The number of entries in the history are controlled by ML_MHIS.

ML_CTIFOR = (average of the stored Bayesian errors) *(1.0 + ML_CX).

This implies that for ML_CX=0, the old value stored in ML_CTIFOR is simply overwritten by the current average Bayesian error.
