BinarySelection plays (except having its classical search meaning) an important role in theory of HR management. It defines what happens when employees are leaving the employer (either voluntarily or after being fired):
BinarySelection means, that "ones" leave and "zeros" stay.
I mention this definition whenever we chat about life of software developers and it always generates grin smile. Of course, because it is so true! I can confess that as for last seventeen years I have been sticking with my job surviving any layoffs and acquisitions: I've seen so many "ones" leaving, but the rest of us is still marching on!
