学术翻译：群体玩家数量可变 - 讨论问题的简化假设

Academic translation: The number of players in each group does not necessarily have to be consistent, allowing for scenarios where different groups have different numbers of players. However, for the sake of convenience in discussing the issue at hand, we assume in Question 1 that there is an equal number of players in each group. Nevertheless, it is relatively easy to extend the discussion from the case of equal numbers to varying numbers, as it only requires adjusting the dimensions of the relevant variables. Therefore, further discussion on scalability is not necessary.
