I am curious how most people are preventing the queen from moving
out? Rewarding it to stay on its original square or penalizing it if
found on other than its original square? How about penalizing it
an amount that is linearly increased by the number of moves its
made so far when other pieces still remain to be developed?

What is the best way to prevent her royal highness from wandering?

(I use the last method but sometimes end up with very high penalties
on the queen after a series of moves that won some material or induced
a very bad positional problem for the computer's opponent.)
