i don't think you will find too many people on this
list knowing that 1 lakh is 100,000. it might be better
to stick to a more common numbering system. ;)

if you do have a very high potential energy system, it is
better to minimize for a smaller number of steps, do a
few MD steps and then minimize again.

you are likely not restarting correctly. impossible to tell
without more information, though.
