Japanese Mahjong Japanese Mahjong Japanese Mahjong (Japanese: 麻雀, 麻将 or マージャン; "mājan"), also known as Rīchi Mahjong, is a variation of mahjong. While the basic rules to the game are retained, the variation features a unique set of rules such as "rīchi" and the use of "dora". The main mahjong article contains general terms, but only English and Japanese terms are used here. Terms like "chow," "pung," and "kong" are not used in this variation, yet their functions are still used. Instead, they are referred to in Japanese as "chī", "pon", and "kan". In 1924, a soldier named Saburo Hirayama brought the
Chow–Liu tree construction are common in the Bayes network literature, e.g., for dealing with loops. See .) Generalizations of the Chow–Liu tree are the so-called t-cherry junction trees. It is proved that the t-cherry junction trees provide a better or at least as good approximation for a discrete multivariate probability distribution as the Chow–Liu tree gives. For the third order t-cherry junction tree see , for the "k"th-order t-cherry junction tree see . The second order t-cherry junction tree is in fact the Chow–Liu tree.
