Wordle Solver

I got bored and wrote a wordle solver... Its pretty good though, just saying. Please go support Josh and have fun with Wordle on the official website https://www.powerlanguage.co.uk/wordle/

TLDR--- Solves in 3.59 turns with a 99% success rate

This solver uses a combination of letter frequency calculations and word list pruning techniques.

I had three goals when writting this code:

1. Write a solver that works
2. Optimize using different techniques
3. Run an experiment to determine if there is a significant difference in the number of turns it takes to solve versus the starting word.

Here are the results of the experiment which can be replicated by running the code yourself.

Top 10 words to start with are: ['tread', 'raspy', 'lusty', 'grand', 'posit', 'shale', 'crust', 'lyric', 'tenor', 'horde']

Worst 10 words to start with are: ['kappa', 'pizza', 'affix', 'fuzzy', 'verve', 'amaze', 'motto', 'queue', 'expel', 'mimic']

Best word to start with: tread
Mean turns to solve: 3.595959595959596
STD: 0.8912178313076166
Success Rate: 99.0++++

Worst word to start with: mimic
Mean turns to solve: 4.515789473684211
STD: 0.943771946564455
Success Rate: 95.0++++
pValue 4.966074332439964e-11

pValue less than 0.05 so we reject the null hypothesis. (there is a significant difference). This just means it matters what word you start with.

• Step 5. Repeat steps 1 - 4 until solved.

An example solve:

Most likely word(s): ['slate', 'sauce', 'slice', 'shale', 'saute', 'share', 'sooty', 'shine', 'suite', 'crane']

Guessed word: slate
Result? Example 12002: 01000
There are 87 words remaining.

Most likely word(s): ['golly', 'dolly', 'folly', 'gully', 'dully', 'bully', 'holly', 'fully', 'jolly', 'dilly']

Guessed word: golly
Result? Example 12002: 01120
There are 2 words remaining.

Most likely word(s): ['droll', 'knoll']

Guessed word: droll
Result? Example 12002: 00222
There are 1 words remaining.

Most likely word(s): ['knoll']

Guessed word: knoll
Result? Example 12002: 22222
