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.
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.
