MAX_DR {Real}  
Convergence criterion for the maximum geometry change between the current and the last optimizer iteration.  
This keyword cannot be repeated and it expects precisely one real.  
Default value: 3.00000000E003  
Default unit: [bohr] 
MAX_FORCE {Real}  
Convergence criterion for the maximum force component of the current configuration.
