Adapter program for playing games between two Go programs supporting GTP (Go Text Protocol).
Optional observer and referee GTP Go programs can be used for observing the game and answering commands related to the final game score. TwoGtp forwards the following commands to all programs (command translation is done for protocol version 1 programs):
The following commands are forwarded to the referee program, if existing, otherwise to first player program that implements them (Black is tried first):
The command genmove is forwarded only to the program of the corresponding color, the other programs are informed about the move with a play command. GTP extension commands implemented by exactly one of the programs are forwarded to the program. The special comment line # interrupt, used by GoGui to interrupt commands, is forwarded to all programs.
If the option -sgffile
is used, the games are
saved after they are finished and a result text file in table format
is created with some statistics.
If the program(s) support the GTP command cputime,
these statistics include CPU times.
The errors in the statistics are the standard errors; they are computed by
the standard deviation of the results, divided by the square root of the
number of unique games, which is correct only for a sufficiently large number
of games (especially if the percentage of wins is close to 0% or 100%).
-alternate
Alternate colors. Black and White are exchanged every odd game;
the scores saved in the results table -sgffile
are still using the name Black and White, as given with
-black
and -white
.
-analyze
file.dat
Analyze the result file
.
Creates a HTML file file.dat
with links to the games and summary statistics.
Also creates a text file
file.html
,
with a table row containing the most important summary statistics.
file.summary.dat
-auto
Automatically play games.
Use this option if you want to run TwoGtp as a
standalone program, without a program like GoGui
which controls the move generation with genmove_black
and genmove_white commands.
If a result file already exists (as specified with -sgffile
),
and contains less games than specified with -games
,
the remaining games will be played.
Use -force
to overwrite existing result files.
-black
command
Command for black program.
-compare
Compare a list of SGF files given as arguments an exit. Works only with SGF files with alternating moves and without setup stones.
-config
file
Read command line options and arguments from file.
-force
Overwrite existing files.
-games
n
Number of games to play (0 means no limit).
-help
Display help and exit.
-komi
komi
Komi. If this option is not used, the komi can be set with the komi command, or a default komi of 6.5 will be used.
-loadsgf
See -openings
.
-observer
command
Command for observer program.
-openings
directory
Use openings from SGF files in the given directory.
The openings will be cycled through in alphabetical order.
If option -alternate
is set, each opening is played twice
with colors exchanged.
There are two ways how the opening moves can be sent to the programs.
By default, all moves and setup stones are sent as alternating
play commands, so instead of forwarding the first
genmove commands to the program to play,
TwoGtp responds with moves from the opening and informs the programs with
play commands.
The advantage of this method is that it still works, if TwoGtp is used
interactively with GoGui as a graphical frontend; however, it is very slow
for opening files containing many moves or setup stones.
Alternatively the option -loadsgf
makes TwoGtp to use
the loadsgf GTP command for setting up openings;
this works only with option -auto
.
Note that TwoGtp has no handicap option yet, but openings can be used
to play handicap games by creating a directory with a single opening
file, containing the position with handicap stones.
-referee
command
Command for referee program.
-sgffile
prefix
Save games after they are finished with filename
(prefix
-n
.sgf
n
is the game number).
The results are appended to the file
.
prefix
.dat
-size
n
Board size for games. If this option is not used, the size will
be set with the boardsize command, or the
default size 19 will be used when option -auto
is set.
-time
timespec
Set time limits (min[+min/moves]).
-verbose
Print debugging messages.
-version
Print version and exit.
-white
command
Command for white program.
Indicate interrupt ability for GoGui. TwoGtp will forward the interrupt to both programs, with the appropriate method, if they implement either gogui_interrupt or gogui_sigint. See Chapter 9, Interrupting Commands of the GoGui documentation.
Return a title for the current game, consisting of the game number (if option
-sgffile
was used) and the player names.
command
Send command to black player.
command
Send command to observer program.
command
Send command to referee program.
command
Send command to white player.
Play 100 games between GNU Go, default level, and GNU Go, level 5, on a 9x9 board, with alternating colors; save games and results to files with filename prefix gnugo5:
BLACK="gnugo --mode gtp"
WHITE="gnugo --mode gtp --level 5"
twogtp -black "$BLACK" -white "$WHITE" -games 100 \
-size 9 -alternate -sgffile gnugo5 -auto
Create a HTML formatted result page of the games played in the previous section:
twogtp -analyze gnugo5.dat
Play one game between GNU Go, default level, and GNU Go, level 5, using GoGui as a graphical display (to start play, select Computer Color/Both from the Game menu in GoGui):
BLACK="gnugo --mode gtp"
WHITE="gnugo --mode gtp --level 5"
gogui -program "twogtp -black \"$BLACK\" -white \"$WHITE\""
Play 100 games with same settings as in the first example, with GoGui as a graphical display (start games automatically):
BLACK="gnugo --mode gtp"
WHITE="gnugo --mode gtp --level 5"
TWOGTP="twogtp -black \"$BLACK\" -white \"$WHITE\" -games 100 \
-size 9 -alternate -sgffile gnugo5"
gogui -size 9 -program "$TWOGTP" -computer-both -auto
