Re: Speed up a slow loop
My memory checks on the Pixel 5 had a maximum app memory use of about 375 MB of RAM. I think that was before I removed the duplicate copy of the dictionary data though, which if so would bring the total down. That said, other apps had more. Chrome browser used over 300 MB, Play Store 411 MB, my mail client 211MB. Those do okay on the phone. And I still don't understand why my cheap tablet with half the RAM handled anything I threw at it, including SOWPODS, without blinking. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com On March 9, 2022 6:53:46 PM Neville Smythe via use-livecode wrote: After button 2, the real memory used is 121 MB (second run 131 MB) So splitting a 2.5 MB file into an array with 275 K keys required 75 MB (this figure was duplicated in the second run) ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
Re: Speed up a slow loop
I just ran a test to try to find out how much RAM is used when you create a large array; the result is rather surprising. BTW Bob: I did not imply that an array is implemented in LC as a database. Merely that to work its magic it must be indexing keys somehow. I had suggested a 2.5 MB list of 275K words might expand to no worse than 10MB when split into an array. Not quite, as it turns out. I wrote a very simple stack which just has two buttons. The first reads SOWPODS.txt into a global variable gWordlist. Don’t try putting that variable into the msg box — LC becomes unusable with the Beachball of Hope spinning for a few seconds whenever you do anything. Aha, it is the LC engine that is having problems with large data (in this case displayed in a field of course, not in the variable itself) The second button puts gWordlist into aa, and splits aa by CR as a set. I then turned the stack into a standalone and looked at the memory used in the Mac Console . When the stack launches, real memory used is 29.8 MB (in a second run 45 MB) That’s the basic LC engine + 18 MB of Mac OS stuff which is shared with all apps, the stack itself would be tiny . after button 1, reading in the 2.5 MB file, the real memory used is 46 MB (second run 56 MB) So 16 MB to store a 2.5 MB file in a variable (in the second run 11 MB, I guess 5 MB of engine code was garbage collected) . After button 2, the real memory used is 121 MB (second run 131 MB) So splitting a 2.5 MB file into an array with 275 K keys required 75 MB (this figure was duplicated in the second run) We are now talking pretty large amounts of memory that the LC engine has to move around, for example probably making copies in its procedure stacks (that's stack in the coding sense). I'm not surprised that LC might be getting indigestion with variables of this size on a small device. I seem to remember running into RAM allocations for an iOS app measured in the low hundreds of MB.

Re: Speed up a slow loop
Hmmm - I have to correct myself :-) It's not 110; there are 144 digraphs on a 5x5 board - nine centre tiles each have 8 neighbours - four corner tiles each have 3 neighbours - twelve remaining edge tiles each have 5 neighbours giving 72 + 12 + 60 - so 144 pairs (already including both directions for each adjacency). Now if you allow edge-to-edge wrapping (i.e. from the top right tile you can move to the right - and find yourself back on the top left, etc.) then there are simply 25 * 8 pairs - but then you've moved a long way from genuine Boggle rules :-) Alex.

[ANN] SpreadLib ordering is back online
The SpreadLib order page is back up: http://livecodeaddons.com/spreadlib.html http://livecodeaddons.com/buy-spreadlib This is NOT a new version! Just the "store restored" after going offline when eSellerate died. (I've marked the price down a bit, though, at SendOwl.) We have a MUCH newer private release made for 2020, but COVID nuked my productivity those last two years, so it never got the License keys for a public release. That's a priority this year, therefore Here's the SpreadLib for 2022 Plan: - Public release during Summer. - New backend integration for more frequent updates. - Newer Mac improvements. - Multi-sheet handling. - Updated and expanded Documentation. - Many more improvements done before 2020. (Meanwhile, WordLib is first in line again, with a minor version coming up around Easter for supercharged MS Word Comments.) Happy coding!

Re: Speed up a slow loop
I'm not sure I followed all that, but did you account for diagonals? It sounds like you'd need to calculate all the possible polygons in a 5x5 grid, starting from anywhere, and sometimes wrapping around itself. I don't have the math skills to do that but when I get this thing presentable you could take a look and see what you think. On 3/8/22 8:32 PM, Quentin Long via use-livecode wrote: It occurs to me that any word which is valid in Boggle must consist of an uninterrupted run of letters which are *right next to each other* on the board. Hence, any digraph which *doesn't* consist of a pair of neighboring letters, *cannot* occur in any valid word. Since the "filter out all words with LettersNotOnTheBoard" idea worked, it may be that an analogous "filter out" operation can speed things up more. When setting up a new board... -- Construct a list of all 576 ( = 26x26 ) digraphs—"aa,ab,ac, … zx,zy,zz". Or, more likely, construct that list ahead of time, and store the list in a stack property.-- Remove all digraphs which contain at least one letter that's not on the board.-- Make a list of all pairs of neighboring letters on the board. Since you don't know which direction an arbitrary digraph is running in, you'll want to include ZA as well as AZ.-- Remove all the digraphs present on the board from the ListOfAllDigraphs.-- Replace all the "," in the ListOfAllDigraphs with "|". (i.e., replace commas with pipes) -- Put "[" & ListOfAllAbsentDigraphs & "]" into RegexPattern.-- Filter WordList without RegexPattern.-- ???-- Profit. Hmmm... since this starts out with a complete list of all 576 digraphs, there's no need to do a separate regex filter on individual letters; filtering out the full list of unused digraphs should encompass filtering out unused letters. Hence, just one regex filter should do the job. I think. On a 4x4 Boggle board, there are 72 neighboring pairs, hence a maximum of 144 valid digraphs; on a 5x5 board, there are 110 neighing pairs, hence a max of 220 digraphs. Hopefully, this won't add too much overhead to board setup. "Bewitched" + "Charlie's Angels" - Charlie = "At Arm's Length" Read the webcomic at [ http://www.atarmslength.net ]!
