The conventional impressions of a shy and awkward Chinese youth may no longer fit into the reality. They have a more and more open mindset towards dating and socializing, said Wang Yu, Chief Executive Officer of Tantan (探探) at TechCrunch Hangzhou. Despite growing audience base, matching them is still not easy.

Tantan’s matches two people when they both like each other on the app. After liking a certain amount of users, the platform will push you users of a similar kind. This is a common strategy used by recommendation systems in various applications. However, there’s always a concern that this will, in the end, limit what users can see or, in Tantan’s scenario, talk to, and possibly miss out the one that fits you most.

Wang said it is difficult for algorithms to achieve both variety and accuracy at the same time. Wang referred to the Nash equilibrium in situations Prisoners’ Dilemma. If people only greedily satisfy their own demand without cooperation when cooperation is in their best interests, the result will not be optimal for the community as a whole. However, unlike prisoners who cannot communicate to form a partnership, algorithms within the platform can see things from a God’s-eye-view.
