Abstract

The purpose of this article is to clarify the fundamentals of the card game Daihinmin. By collecting logs of Daihinmin games on a large scale and analyzing them, the authors illuminate the game's characteristics. They discuss the content required from the game to this end and examine the types of logs that must be collected. They then report on the collection of various logs and the calculation of certain features to characterize Daihinmin. Furthermore, the authors investigate the relationship between the initial hands and rankings of players, as well as the influence of the exchange rule, through a computer experiment.

2. Computer Daihinmin

Daihinmin is a card game mainly played in Japan, but similar games are played around the world. It is a multiplayer game of imperfect information that has been extensively studied in recent years. Computer Daihinmin refers to playing the game on a computer. The UEC Computer Daihinmin Convention is an annual competition for computer Daihinmin programs. Several thousand games are played in the competition each year by computers with extreme computational capabilities. The competing algorithms seek to win without the influence of an initial hand over the course of many games.

In this study, we adopt the framework utilized by the UECda. While there are numerous sets of localized Daihinmin rules, the UECda implements the specific rules outlined below:
