https://github.com/psaris/wordle  demonstrates how wordle is an extension to the mastermind game (https://github.com/psaris/mm).

the README.md describes the mastermind algorithm and how it can be used to solve wordle.

an example demonstrating how the algorithm guesses a random word is demonstrated below:

 

q)l mm/mm.q 
q)l wordle.q 
q).mm.score:.mm.veca .wordle.scr 
q)C:asc upper read0 `:answers.txt 
q)G:asc C,upper read0 `:guesses.txt 
q)g:"SOARE" 
q)a:.mm.onestep `.mm.maxent 
q).mm.summary each .mm.game[a;G;C;g] 
rand C n guess score 
-------------------- 
2309 "SOARE" " G G" 28 "GLITZ" " " 
8 "HEAVE" " GG G" 1 "PEACE" "GGGGG"

 

the speed at finding the optimal solution depends critically on the scoring function.

this is my implementation.  eager for improvements!

 

/ redefine the mastermind scoring functions 
.mm.scr:{[g;c] g[w:(i:group e_g=c) 1b]:" "; 
/ identify and skip where equal 
i@:where count[c]>i:g ? c i 0b; 
/ identify where misplaced 
s:@[" G" e;i except w;:;"Y"]; / generate score s}

 

sample usage:

q).mm.scr["RIGHT";"RIGHT"] "GGGGG" 
q).mm.scr["RIGHT";"WRONG"] "Y Y "

 

and an example with duplicate letters:

q).mm.scr["RIITE";"RIGHT"] "GG Y " 
q).mm.scr["RIGHT";"RIITE"] "GG Y"
