pentobi - computer opponent for the board game Blokus


pentobi [options] [file]


pentobi is the command to invoke the program Pentobi, which is a graphical user interface and computer opponent to play the board game Blokus. The command can take the name of a game file to open at startup as an optional argument. The game file is expected to be in Pentobi's SGF format as documented in doc/blksgf/Pen‐ tobi-SGF.html in the Pentobi source package.


--maxlevel Set the maximum playing level. Reducing this value reduces the amount of memory used by the search, which can be useful to run Pentobi on systems that have low memory or are too slow to use the highest levels. By default, Pentobi currently allocates up to 2 GB (but not more than a quarter of the physical memory available on the system). Reducing the maximum level to 8 currently reduces this amount by a factor of 3 to 4 and lower maximum levels even more. -h, --help Display help and exit. --nobook Do not use opening books. --nodelay Do not delay fast computer moves. By default, the computer player adds a small delay if the move generation took less than a second to make it easier for the human to follow the game if the computer plays several moves in a row. --seed Set the seed for the random generator. Using a fixed seed makes the move generation deterministic if no multi-threading is used (see option --threads). --threads The number of threads to use in the search. By default, up to 4 threads are used in the search depending on the number of hardware threads supported by the current system. Using more threads will speed up the move generation but using a very high number of threads (e.g. more than 8) can degrade the playing strength in higher playing levels. --verbose Print internal information about the move generation and other debugging informa‐ tion to standard error.
