GCMC - no of steps to run

Dear all,

I have very basic question. We specify the no of steps to run in gcmc calculation. How can we know that we have to run for these many steps, for eg: i can run for 10^6 or 10^7 steps but the later takes more computational time. How to choose optimum no of steps for gcmc calculation?

Thanks & regards,

Dear all,
              I have very basic question.

basic questions almost always warrant a thorough look into a suitable
text book on the topic and then a discussion with a more experienced
colleague or tutor or adviser.

there is no simple answer for that outside of "you have to keep going
until it is enough".
for the explanation why, please refer to a text book on statistical mechanics.
those explanations are better than what i could ever write.
