Wordle Solver has a few command line options.
USAGE: solve-wordle [<solution-string>] [--start <start>] [--all] [--best-start]
ARGUMENTS:
<solution-string> The solution to use for the puzzle.
OPTIONS:
--start <start> The word to use as a first guess.
--all Solve all possible puzzles.
--best-start Solve best start word.
-h, --help Show help information.
Wordle Solver is under active development.
The bestWord(from:) function simply chooses a random word from the remaining word list.
Running solve-wordle --all produced:
It took an average of 4.1 turns to solve all Wordles.
48 puzzles were not solved.
The bestWord(from:) function chooses the word that has the fewest remaining options for all
possible solutions.
That is, it will have the fewest average solutions after guessing it.
Running solve-wordle --best-start produced:
The best start word according to the current heuristic is 'RAISE'.
Because of that, 'RAISE' has been hardcoded as the default start word so that it doesn't need to be calculated every time.
The --start <start> option was added to override the default start word.
Finally, running solve-wordle --all produced:
It took an average of 3.6 turns to solve all Wordles.
14 puzzles were not solved.
