Recommended system for bi-directional selection

Most of the typical recommendation system for the "user-commodity" this model down to research, and then in reality there is another mode of "user-user" or "commodity-commodity" phenomenon, the former such as dating and marriage network, the latter is a job network and so on. For friends and marriage network, in addition to the husband of the woman has a good opinion, the woman also to the man's heart to match the situation can be paired with a love, the same job site to recommend me a Google CEO work, I will be interested, but he is not interested in me is meaningless. In this way, it seems that the traditional recommendation mode is not applicable here.

The proposed algorithm has reciprocal recommendation, which is recommended for this kind of bi-directional selection. This algorithm has been issued some paper, but not many, for the time being noted, and later added.
