dd_table_for_deal

Run via Bazel

bazelisk run //python/utilities:dd_table_for_deal "N:73.QJT.AQ54.T752 QT6.876.KJ9.AQ84 5.A95432.7632.K6 AKJ9842.K.T8.J93"

or

bazelisk run //python/utilities:dd_table_for_deal -- hands/example.pbn
bazelisk run //python/utilities:dd_table_for_deal -- --vul ns hands/example.pbn
bazelisk run //python/utilities:dd_table_for_deal -- --limit 3 hands/multi_board.pbn

Run without Bazel

To run the utilities directly, without Bazel, first build the native module and set PYTHONPATH:

bazelisk build //python:_dds3
export PYTHONPATH=python:bazel-bin/python

Direct commands:

python python/utilities/src/dd_table_for_deal.py "N:73.QJT.AQ54.T752 QT6.876.KJ9.AQ84 5.A95432.7632.K6 AKJ9842.K.T8.J93"

or

python python/utilities/src/dd_table_for_deal.py hands/example.pbn

benchmark

Runs dtest timing comparisons. Wrapper at repo root: ./benchmark.sh.

bazelisk run //python/utilities:benchmark
python python/utilities/src/benchmark.py --build -- -n 8

create_list_for_dtest

Generate random dtest hand-list files (conventionally listNNN.txt with --seed NNN).

bazelisk run //python/utilities:create_list_for_dtest -- -n 100 --seed 100 -o hands/list100.txt
bazelisk test //python/utilities:create_list_for_dtest_test

See also utilities/src/regenerate_hand_lists.sh and utilities/src/verify_lists.sh.
