Thought you guys might find this interesting. This video is about a match-making algorithm which takes two groups of people, has them submit a "preference list," and then pairs up people from each group.

The interesting thing is that the algorithm uses a series of "proposals" and "rejections." It's not a perfect corollary to how actual dating works, but it is close enough to provoke some interesting thoughts.

The algorithm always favors one group over the other; namely, the group that is doing the proposing, rather than the group doing the rejecting. In the video, the example scenario used is women proposing to men, but when the algorithm was first developed, it was men proposing to women.
