          The referee shall judge the outcome by the following procedure.
          1. To the greatest extent possible, judge dead/alive by referring to the judgment of dead/alive by both programs.
          2. If the programs can roughly calculate the territories, decide win/ lose by using the result.
          3. If the programs find it difficult to judge the territories, the referee makes the better judgment to decide on win/lose. However, in this case, the portion where the dead / alive judgment of both programs matches, shall be judged on the assumption that it is correct.
