单词	lower bound
释义	Lower Bound A value that is less than or equal to every element of a set of data. Example: in {3,5,11,20,22} 3 is a lower bound. But be careful! 2 is also a lower bound (it is less than any element of that set), in fact any value 3 or less is a lower bound. Example: how tall is a human? We may not know the exact shortest human, but we can say that 0 is a lower bound (can't be less than zero in height, right?)
