Important changes

• We decided not to allow the operator to resign.
• It was strictly stressed that operators cannot touch any input device on the computer during the game.
• The item of “Abnormal termination of programs" was deleted from the stop condition of the game. If a program does not return the next move due to abnormal termination and so on, the game will continue until the expiration of time.
• The item of "In case of the normal progress of the game cannot be made" was added. In such case, operators must seek the judgement of the referee promptly.

• Until the past competitions, the game started with the "match" command by players, but the "adminmatch" command is newly established and the start of the game will be decided by the administrator. Be aware that the previous "match" command can no longer be used!

≫We prepared a new ruby script and CGF board for bridging between NNGS and GTP. Please download it from the following page.

> GTP_20180715.tar.gz ruby script: tie the GTP engine to nngs. It is incompatible with the previous one.

> cgfgoban109.zip CGF board: Added an option that can be connected to AI Longyan Battle.

# Since the administrator will start the game, the game will not start even if you log in the two programs. The ruby script does not need to designate an opponent, but you need to correctly set the opponent's black and white on the CGF board.

• The item of "Categories of participation" was deleted.
• Programs with a source code that is permissible to use (in this competition by its developer) are permitted to participate. However, such programs must add an explicit unique contrivance.
• All participants (not only the program with other source code but also original program), when making an application, must submit an appeal summary that describes the features of your program. The appeal summary will be released at the competition website.

• On the second day (final), the final ranking is decided by round-robin competition by the two ranking leagues (1st to 6th in the A-League, 7th to 12th in the B-League) of the top 12 teams following the order of the preliminary-match ranking.
• The first day (preliminary match) is carried out in an anomalistic Swiss style as before.
