Written mostly by GitHub Copilot.
The rest here is actually Copilot babble, trying to write a readme.
A demonstration of a project written by Copilot. At least in part, this project is a wordle solver. When Copilot is not programming, he is playing a game called "Wordle". Let's try if he can solve it.
This code implements a 'good' strategy, not an optimal one. For optimal strategies, check Jonathan Olson's page.
Python 3.10
import wordle
import solver
solver.RandomSolver(wordle.Game(word_index=1)).solve(verbose=True)
# solve all challenges, calculate percentage solved
run = [
solver.RandomSolver(wordle.Game(word_index=i)).solve(max_rounds=6)
for i in range(len(wordle.words.challenges))
]
sum(1 for rounds, _ in run if rounds < 6) / len(wordle.words.challenges)
# 54% of challenges solved
# EntropySolver is used in similar manner
solver.EntropySolver(wordle.Game(word_index=1)).solve(verbose=True, max_rounds=6)
run = [
solver.EntropySolver(wordle.Game(word_index=i)).solve(max_rounds=6)
for i in range(len(wordle.words.challenges))
]
sum(1 for rounds, _ in run if rounds < 6) / len(wordle.words.challenges)
# 100% of challenges solved
import statistics
statistics.mean(r+1 for r, _ in run)
# 3.639
# a histogram
[(k, cc[k]) for k in sorted(cc.keys())]
[(1, 22), (2, 898), (3, 1284), (4, 102), (5, 3)]
# the difficult words
[(i, w) for i, (r, w) in enumerate(run) if r == 5]
[(145, 'baker'), (2219, 'wafer'), (2229, 'waver')]
At start there are no clues. soare is the word that is picked every time by
the EntropySolver. We can also pre-compute the candidates based on pattern after
the first guess and the best guess for those candidates.
import wordle, solver
soare_patterns = set(wordle.eval_guess(c, 'soare') for c in wordle.words.challenges)
soare_cands = {pat:solver.filter(wordle.words.challenges, 'soare', pat) for pat in soare_patterns}
soare_guess = {pat:max(solver.entropies(wordle.words.all, cands), key=lambda x: x[0]) for pat, cands in soare_cands.items()}
with open('soare.p', 'wb') as fo:
pickle.dump(((0, 'soare'), soare_cands, soare_guess), fo, protocol=pickle.HIGHEST_PROTOCOL)
