Exploring Cooperative Game Mechanisms of Scientific Coauthorship Networks

Figure 1

An illustration of an evolutionary research team. At each time, a new player joins the research team, and the group of the players with white numbers forms a hyperedge. It illustrates a usual scene. New coming player 6 wants to complete a work and write it as a paper. Suppose completing the paper needs four players. Then player 6 would ask leader 1 for help, and the leader would suggest team members 2 and 3, who have the most similar interest to player 6, to cooperate.
