WebSep 28, 2011 · Yes, binary search is optimal. This is easily seen by appealing to information theory. It takes log N bits merely to identify a unique element out of N elements. But each comparison only gives you one bit of information. Therefore, you must perform log N comparisons to identify a unique element. More verbosely...
