竞技二打一游戏中同等牌力的研究

全国竞技二打一扑克锦标赛是国家体育总局棋牌运动管理中心推出的新兴项目，比赛采用复式赛赛制，然而这种赛制存在无法杜绝线上比赛作弊的问题，为此提出用同等牌力赛制来代替复式赛制进行比赛的设想。本文主要针对如何判定和选取具有同等牌力的初始手牌进行研究，提出用等级难度评估指标来计算初始手牌的难度，初始手牌难度相近的牌认定为同等牌力，并给出了同等牌力的选取方法；为保证一副牌所得等级难度评估指标的可靠性，提出用多个不同水平的“二打一AI程序”来代替真人打牌产生牌谱的方法。实验证明了同等牌力生成方法的有效性，本文提出的同等牌力方法应用于比赛是可行的。

Research on the equal card force competition system of competitive two against one game

The General Administration of Sport of China launched a new project that uses a double competition system, namely, the National Competitive Doudizhu (Two-on-One) Poker Tournament; however, this system does not eliminate online cheating. As a remedy, the idea of using the equal card force competition system to replace the double competition system has been proposed. This paper focuses mainly on how to judge and select the initial hand with equal card force, suggesting the evaluation index of grade difficulty as a method of measuring the difficulty of the initial hand. This system offers a way to select cards of equal card force. Cards of similar grade difficulty in the initial hand are considered to have equal card force. To ensure the reliability of the resultant evaluation of a deck of cards, this paper proposes an innovative “Doudizhu AI program” with different levels as an alternative. The validity of this method is verified by experiments. It is feasible to apply this method in competitions.
