It attempts to avoid steps that are too large and can help improve robustness 
of convergence in some cases.

Hello everyone,

 

I’ve been wondering about what does the “optional step-control” part of the 
MIPS algorithm serves for.

 

Ok, I understand it must be associated with the MIPS alphaD and alphaP steps, 
but I wonder for what kind of particular conditions it is useful. 

 

Does it try to accelerate convergence? Does it solve convergence problems?

 

Thank you in advance.

 

Best regards,

André
