Boggle play against AI - WIP
« on: January 13, 2022, 11:46:33 am »
https://en.wikipedia.org/wiki/Boggle

The AI is going to be handicapped starting with only 1 point words (3 or 4 letters words from Scrabble Dictionary that don't use Q (that is 2 points)) and maybe a shorter time limit too.

Just got started last night from trying to figure out Dimster's "Babble" Game, I thought he might mean Boggle?

Any way got a board working:

Dang the Collins Dictionary is too big to load, QB64 keeps bugging out, no error message, just quits.
279,496 words

The amount of words I could store and not in terrible time was about 260,000 before QB64 (on my Windows 10 laptop system) bugged out without so much as error message, at least it didn't crash the whole system. Tried Open For Input and Open For Binary, one gulp method. OK it's 2.96 MB according to properties Window.

I have already worked a fairly practical workaround by limiting the words by number of letters, another maybe not to load the dictionary at all and just search for words in the hard disk by turning it into a Random access file or something.

But I wonder if there is another way to get the dictionary loaded into program whole. Is about 1 MB the limit for variable length string memory?

Oh boy! Just got the trickiest Function working :)

It's the one that confirms a word can or can not be legally built from a given board. Interestingly it uses a recursive function to seek out the rest of the word from a given letter location once the first letter has been matched from the game board. I am a bit shocked, it's like magic :)

 (Of course the shock would have been worse had it worked right off.)

Update: OK same logic bug happened in the recursive helper function, more subtle, I think I have them exterminated now.

That AI looks like it will need more handicap, here is what it came up with in 30 secs. Looks like that was enough time to test the whole dang OnePointList$(). I've still got to work out dealing with special case Q amongst checking player redundant words, scoring and handicapping.

The first test of AI play:

  12. '   2. check that word can legally be built from board is funky! sometimes works sometimes not 50/50 for legit builds yuck
  13. '     How to debug? Todays task is get this abolutely critical function working so the AI would be fairly easy to do.

Ah word games, checkout @Qwerkey plus crosswords and another about snaking word around a grid maybe like Boggle? It was from a newspaper puzzle and it was awhile ago and I may have author confused with someone else?

Bplus also did WordSearch had a pretty good package for Rosetta Code Challenge but interacting with Richard Frost and his work of getting all the elements of periodic table to fit in a grid really improved my game. I think I got to point of building word searches for your own list of items.

OK I have basic game roughed out. Now I am handling the Q(u) Letter better still needs more testing. I need a qu? word that is 3 letters with u, to see if you type 2 letters the first a q and enter q? the word will be added to your list. BTW the 1 Point List that the AI uses doesn't have any Q words because originally I thought Q words were 2 points. No Q words contain the hidden letter U which could potentially make the word a letter longer that the one you type and points are awarded by number of letters. All the goofiness in coding could have been simplified by having 1 die with Q and maybe a couple extra u's and other vowels. That may be a mod down the line from here 17 dice, the 17th with aeiouu. This game is boring if have a whole bunch of constanents (sp? for not-a-vowel).

Now there is a Sleep between seeing your list and AI's before matching words are removed from both lists and final score calculated and shown. Yours will likely be 0 unless you come up with 5 or more letter words but at lest all your 3-4 letter word will negate the AI's.

Why doesn't the AI find PEAT and DIE and TAP?

It's overlooking a lot of easy words.

It's overlooking a lot of easy words.

They were on my list ("a lot of easy words"), at time of reckoning matching words are eliminated and then words remaining are scored.

You see those words on the screen shot before the last (when I had words in my list). The AI of course found every 3-4 letter word I did (wiping out my list) plus a couple more, it gets to keep the couple more :)

I will add a label about typing in the words while the timer is going, but I have bigger fish to fry. I want that 17th die to eliminate special handling of Qwords that really threw a monkey wrench in coding this game and AI's list will have access to ALL 3 and 4 letter words. There many q words that don't use u after the q, why should we shun them?

We play games but we also expand vocabulary, spelling and data processing skills ie keep our minds active and growing.

Hi bplus
about the program simply vanishing while reading the dictionary, try Dim WordList$(1 To 300000) even though the number of words is only 279499
but where can I find "Boggle 1 Point Words.txt" ?

but where can I find "Boggle 1 Point Words.txt" ?

Apologies to all, I forgot you guys need the files to play, dang sorry.

Use the link for the giant Collins Scrabble Word (2019).txt files, I would get the dictionary with the word list to learn what some of these crazy 3-4 letter words are!? You can find the link right under the Boggle Title line at the start of the bas source of Boggle 1.

And here is the zip for the Bas Make codes ran to create smaller files from the Collins word list.

+1) The 3 to 10 Letter Words.txt is my fix for being unable to load the entire Collins Word List as mention in reply above. Might be able to get more Letter words thn 10 but I roughing out a running game not optimizing.
This file was used to load most of the words into an array in the app, as all the words wont fit.

+2) The Boggle 1 Point Words.txt are what the AI uses to attempt legal constructions from the given active game board. One point words only have 3 or 4 Letters.

So in the zip you have the txt file lists and the code that built them from the Collins files and the Boggle 1 source, but not the Collins files.
 

Thanks @jack for bringing this to my attention.


You know since the frick'n AI is so good at finding words, I think I will restrict it to 5 letters or more and give all the one pointers the player finds to the player. That will occupy the AI for finding longer words (and getting bigger points unless player finds them too.)

That may make a game the player could win! ;-)) and it would be more interesting checking out what the AI finds.

Give the AI an education level that the user can select from 1 to 10.

1 has a 10% chance to "know" a word if it finds a match; 10 has a 100% chance.

For example, the AI finds "cat", but with the handicap, it only has a 10 * level percent chance of keeping the word in its list.

Seems simple enough to implement and allows for some customization for game difficulty.
