Title: Codeword solver
Post by: david_uwi on July 06, 2020, 07:18:43 am

Code word is a type of puzzle that has appeared recently (maybe?).
It is like a crossword but there are no clues, instead the grid has numbers which correspond to letters of the alphabet (1 to 26 - not in order obviously).
You have to try to fit in words that will work in the grid and have one letter per number.
It is often difficult to get a start so I have written this program that will search a word list.
There are comment line at the beginning that explain the input.
As a hint longer words are often best as there are much fewer words with 10 letters than there are with 5 also the pattern of repeated and unique letters is larger. There is also a function to eliminate known letters, but this has not been tested.

Code: QB64: [Select]

OPEN "c:\cw1\dictionary_english.dic" FOR INPUT AS #1
DIM word$(320000)
DIM ii AS LONG
DIM q1 AS STRING * 1, q2 AS STRING * 1 'there are problems if these are not dimensioned
DIM wdot(25) AS STRING * 1, wndot(25) AS STRING * 1, wndot1(25) AS STRING * 1
DIM w2(7) AS STRING * 1, w3(7) AS STRING * 1, w4(7) AS STRING * 1, w5(7) AS STRING * 1
DIM ex1 AS STRING * 1
DIM r1$(20)

Hi @david_uwi

I tried your code and ran smack into problem of not having Dictionary file, you might include that with your code in a .zip package or recommend a file to download (that your code can work with) from Internet.

Title: Re: Code word solver
Post by: david_uwi on July 06, 2020, 11:31:12 am

here's the word list I use (it is crap) I'm sure you can find a better one.
Change the number in the loading loop to the number of words in your word list of choice.

Title: Re: Code word solver
Post by: bplus on July 06, 2020, 11:40:43 am

Yes, I have a couple lists but your code appears to be using one of a particular size.

Right now I just wanted to see what you're doing, thanks for your copy.

David, you might be interested in my cipher crossword program

Well the file you passed is password protected. 😒

Title: Re: Code word solver
Post by: david_uwi on July 06, 2020, 12:09:10 pm

Here it is unzipped. I downloaded it when I had very limited internet access. It has a lot of rubbish words and a few obvious missing word (particularly composite -see sweetpea and chequerboard).
I've just done an online search of codeword solvers and they use much the same notation as mine -maybe there is only so many way of doing it. Note my multiple letters start at 2 as 1 looked too much like a lower case L.

Well how long does this word input need to go on?

I put in about 2 dozen words and the last was "end" and that was that! This is not fun so far, maybe some more instruction please.

BTW the new file did work when I removed the path.

This thing seems stuck in endless word input loop.

Yes it does take a while for all the words to load (I've got a SSD).
The searching is much quicker when loaded in RAM rather than on the hard drive so that is the reason for this.
Don't put in end as that is the word that I used to stop execution.
At the prompt put in .2334.4n52.54 (this was an actual example from a "sunday telegraph" puzzle)
the string indicates that there is a "N" in the middle (a known letter)
positions 2 and 9 are the same letter, positions 3 and 4 likewise 5,7 and 13 are the same 9 and 12 are also the same.
The dots represent single unknown letters.
In the actual codeword the numbers were 13,8,21,21,4,16,4,n,3,8,10,3,4 and this is also accepted as input.
Both will give just one word differentiate, which may be enough to solve (with a bit of thought) the whole puzzle.

Oh so this helps you solve puzzles you are working on from the paper! Sorry I thought you had some word game going.

Now I get it. Cool!

I did something similar for a Word Puzzle called the Scrambler, you unscramble the words and then used circled letters to solve a question from cartoon and caption that usually involves a clever pun.
