Just an idea: If a zero follows a 1, it cannot be the minimum. So you can ommit all the zeros preceded by ones (remove them also), recursively. At the end, there are just zeros followed by ones. The last zero is the minimum (or the first 1 if there are no zeros). Does it help?
Update: re-worded (underscored).
