Hi,

having an issue which might just be misunderstanding the cli. I'm just trying to run a limit holdem 2p game.

./pure_cfr games/holdem.limit.2p.reverse_blinds.game test.limit --status=1 --max-walltime=30

GAME_FILE games/holdem.limit.2p.reverse_blinds.game
OUTPUT_PREFIX test.limit
RNG_SEEDS 6 12 1983 28
CARD_ABSTRACTION NULL
ACTION_ABSTRACTION NULL
NUM_THREADS 1
STATUS_FREQ_SECONDS 1
DUMP_TIMER 2147483647 1 0
MAX_WALLTIME_SECONDS 30
DO_AVERAGE TRUE
PARAMETERS_END
Initializing Pure CFR machine... pure_cfr: entries.hpp:119: Entries_der::Entries_der(size_t, size_t, T*) [with T = int; size_t = long unsigned int]: Assertion `entries != NULL' failed.
Aborted

I am specifically interested in games with larger sets of hands (eg Pot Limit Omaha with a bet sizing abstraction) and game types with heavy suit symmetries (eg games where the low hand wins and flushes / straights are ignored).

If you could point me to the key classes where hand evaluation is done and where suit symmetries on the game tree are calculated that would be much appreciated.

Thanks!

Hello Richard,

What does card --card-abs=<NULL|BLIND> option really do? By reading the papers I understood that using CFR you could use a "bucket" system which basically allows you to group the solution instead of holding all possible solution (in the case of nolimit holdem there are too much).

Does it mean that currently open-pure-cfr doesn't save any cards data and doesn't really has this "bucket" way of grouping cards? so how it even work by BLIND cards, I'm a bit confused.

Thanks! :)
