Life and death judgement system for go game

Abstract

Provided is a life and death judgment system for a go game played with a computer, having an input reception unit that receives an input, a life and death judgment processing unit that judges whether judgment subject stones or target stones are alive, and an output processing unit that outputs the result of the life and death judgment. The life and death judgment processing unit tentatively determines the priority of a move at each point when processing life and death judgment in a predetermined judgment realm, judges a point of a move with a high possibility and/or a move with a low possibility of giving a result of the life and death judgment, changes the priority of the point of the move at each tentatively determined point, and undertakes the move of each stone in accordance with the priority after such change, thereby processing the life and death judgment.

1 . A life and death judgment system for a Go game characterized in that life and death of a Go is determined by the use of a computer, wherein
 said life and death judgment system comprises   an input reception unit which receives an input by a player,   a life and death judgment processing unit that determines whether the judgment object stone or target stone is alive, and   an output processing unit which outputs the result of life and death judgment made by said life and death judgment processing unit; and   said life and death judgment processing unit   places a stone of a color which is different from that of the judgment object stone in the predetermined judgment realm in accordance with a given condition, and   carries out the processing of life and death judgment after said placement is made on the board.   
     
     
         2 . A life and death judgment system for a Go game for determining life and death of a Go by use of a computer, wherein said life and death judgment system comprises;
 an input unit configured to receive an input by a player,   a life and death judgment processor configured to determine whether a judgment object stone or target stone is alive,   an output unit configured to output a result of life and death judgment made by said life and death judgment processor, and   a memory;   wherein said life and death judgment processor is further configured to count a number of E-vacant points of a judgment object stone or target stone, determine a move of an offence side or defense side based on the number of said E-vacant points if the number of E-vacant points is two or more, and implement a life and death judgment based on the determined move.   
     
     
         3 . A life and death judgment system for a Go game for determining life and death of a Go by use of a computer, wherein said life and death judgment system comprises;
 an input unit configured to receive an input by a player,   a life and death judgment processor configured to determine whether a judgment object stone or target stone is alive,   an output unit configured to output a result of life and death judgment made by said life and death judgment processor, and   a memory;   wherein   said life and death judgment processor comprises   an processor-executable E-vacant point count processing module which counts a number of E-vacant point of a judgment object stone or target stone, and   a processor-executable life and death judgment execution module which implement a life and death judgment by determining a priority of a move of offence side or defense side based on the number of E-vacant points counted by said E-vacant point if the number of E-vacant points is two or more, and alternately repeating moves of the offense side or defense side according to the priority.   
     
     
         4 . A life and death judgment system for a Go game for determining life and death of a Go by use of a computer, wherein said life and death judgment system comprises;
 an input unit configured to receive an input by a player,   a life and death judgment processor configured to determine whether a judgment object stone or target stone is alive,   an output unit configured to output a result of life and death judgment made by said life and death judgment processor, and   a memory;   wherein   said life and death judgment processor is further configured to accept a designation of one or more target stones as said judgment object stones, implement a life and death judgment on said accepted one or more target stones, and determine if one of said target stones is captured or all of said target stones are captured.
