COMMAND LINE OPTIONS
Usage:
phalanx [options] [<moves> <minutes> [<increment in seconds>]]
phalanx [options] [<seconds per move>]
phalanx bench
phalanx bcreate [book creation options]
Options:
-t <transposition table size in kilobytes>
Transposition table really needs to fit in the RAM memory, it should
never be swapped to disk. Maximum size is your total RAM minus space
needed for OS (8-20 MB) minus space for other (possible) applications.
-f <fixed search time in seconds>
-x <+/-> xboard mode on/off default: on
"Xboard mode off" is designed for the ascii interface. In -s+ mode it
shows also the move that is currently searched.
-p <+/-> permanent brain on/off default: off
Phalanx ponders on a predicted move with the permanent brain on. It is
sometimes called pondering. Xboard sets it on with the 'hard' command
regardless of this option, just use xboard menu to set it on/off.
-s <+/-> show thinking on/off default: off
Phalanx shows depth, evaluation, time used in centiseconds, nodes
searched, and principal variation (best line) when searching. Xboard
overrides this option with 'post' and 'nopost' commands, just use
xboard menu instead of this.
-c <+/-> cpu time default: off
This one defaults to the "wall clock" real time. It's better to use
the CPU time when running test suites.
-o <+/-> polling input default: on
Use -o- for running test suites. Phalanx reads the positions from its
standard input and polling input makes it stop thinking after almost
zero seconds on each position.
-b <+/-> opening book default: on
-l <+/-> learning on/off default: on
-r <resign value in centipawns> default: 0 (no resigning)
-e <easy level 0...99> default: 0 (best play)
1 is the easiest and 99 is the hardest easy level. Phalanx tries to
emulate human-like blunders, the higher the number the more blunders it
plays. It also adds more randomness with the easy levels, repeating
games should be impossible. Easy levels set hashtable size to zero,
pondering and learning to off. Since version XXIII, Phalanx uses
the time normally, it does not respond immediatelly. NPS is lowered
to 100-300, unless overriden by the -n agrument. Root moves randomizing
is used here as well, between 10 to 60 centipawns, unless overriden
by the -z argument.
-z <random evaluation in centipawns> default: 0 (best play)
Randomize play. Add pseudo-random values to root moves evaluations.
The numeric value limits the random range, the interval of random
evaluations to be added is [-N/2 ... N/2].
-n <nodes per second> default: 0 (no limit)
Limits the speed to weaken the engine and to use less resources: The
speed of the machine does not matter here, it uses usleep() during
the search, so with low NPS it does not raise the machine load.
-v
Print version and exit.
-P <primary book directory>
-S <secondary book directory>
-L <learning file directory>
-g <log file name>
