Patent GB-2533007-A (GB)
Title: Efficient modulo calculation
Inventor: SIMON FENNEY
IPC: G06F7/72
Filed: 2015-05-27
Abstract: Apparatus to perform modulo calculation with respect to a constant value b. comprising a series of addition units (each comprising a plurality of binary adders). A first stage addition unit in the series groups bits from an input number into a number of strings, multiplies each string by a corresponding coefficient using adders and left-shifting and adds the resulting strings together to generate an intermediate value which, in most examples, has a smaller range of possible values than the input number. The series of addition units also includes a second stage addition unit and/or a final stage addition unit. A second stage addition unit uses similar methods to generate an updated intermediate value in a pre-defined terminating range. A final stage addition unit generates a final result from the final intermediate result output by an immediately previous addition unit in the series.

Title: New game "Shiki"
Inventor: MIZUTANI YOSHIHIRO
IPC: A63F3/02
Filed: 2013-05-02
Abstract: [Problem] The problem to be resolved is to invent a new game independent from the domain of a Go game in order to dramatically extend the possibilities of the same to the world of a different dimension. [Solution] The first is an improvement of the board. With respect to the 19Ã—19 board of a Go game, the new game adopts a 27Ã—27 board. The second is an improvement in how a stone is put. I know that it is necessary to address the same using a method in which stones are put alternately two moves at a time, and adopted the same. Thereby, it becomes possible to configure a game that is twice larger, quantitatively speaking, using an equivalent number of moves and amount of time as in the prior art, and to be more pleasant, in a shorter amount of time. The third is an improvement in the rules. In the new game, in order to maintain fairness between the players who move first and second, the first placement, i.e., the first move of the player moving first, is set to be one stone only. In addition, with regard to the handicap "Komi" imparted to the player moving second by the player moving first, it is set that 8 stones be imparted to the second player's turn from the first player's turn. The above-mentioned three points are significant features of the new game, and are critical components for functioning as one balanced superior game.
