- Rename module to gitea.iliadenisov.ru/developer/scrabble-solver so it can be
consumed as a versioned dependency (no go.work replace / CI clone).
- De-internalize wordlist and dictdawg as public packages.
- Remove cmd/builddict, dictprep/, the dictionaries submodule and the dawg
Makefile: the word-list parsing and DAWG build now live in the separate
scrabble-dictionary repository, which publishes the DAWG set as a release artifact.
- internal/dict loads the committed dawg/en_sowpods.dawg fixture for cmd/stress.
- Update README/CLAUDE docs accordingly.
Replay 17 real tournament games (cross-tables.com, including the 700+ club) and
check, move for move, that:
- ScorePlay reproduces the protocol score and running total exactly;
- the move generator produces every dictionary-valid played move with that score.
The GCG parser handles coordinates (across/down), blanks (lowercase), played-through
tiles ("."), passes/exchanges, challenge bonuses, end-game rack adjustments and phony
withdrawals ("--", un-applied). Uses the committed dawg/en_sowpods.dawg.
Build a committed Russian common-noun word list (dictprep/russian/scrabble.txt)
from the RAN orthographic dictionary, for the Эрудит ruleset.
- Stage 1 (Go, dictprep/ruwords): orfo_dict_2025.txt -> all.txt; extracts
headwords, reconstructs "ед." singulars (suppressing plurals), pairs "и" variants.
- Stage 2 (Python brain, dictprep/ru_stage2.py): OpenCorpora (mawo-pymorphy3) +
libmorph + orthographic notes select common nouns (nom. sing.); --trace explains
a word's fate, --dump writes the in-memory buckets.
- libmorph C++ bridge (libmorph_check.cpp); manual_confirm.txt is merged in.
- orfo_dict_2025.txt is the committed pdftotext source of truth.
- See dictprep/README.md for methodology and reproducibility.
A Go library that returns every legal play ranked by score and scores or
validates plays, using the Appel-Jacobson DAWG algorithm over
github.com/iliadenisov/dafsa v1.1.0.
- DAWG move generation (across / down / both), full tournament scoring with a
per-tile breakdown; public Solver: GenerateMoves (ranked), ScorePlay,
ValidatePlay.
- Rulesets: English Scrabble, Russian Scrabble, Эрудит (parameterizable Ruleset).
- cmd/builddict (build the DAWG from the dictionaries submodule), cmd/stress
(self-play benchmark), selfplay engine; brute-force test oracle.
- A GADDAG was implemented, benchmarked and removed (the DAWG was smaller and
faster for a scoring solver); see RESULTS.md and ALGORITHM.md.
