Re: delete end chars
Hi Richmond, Wouldn’t that just delete the last char? I need to check for all characters in the first string to see if they all exist in the same order of the last chars of the second string. I know I could use a repeat to see if the characters all exist and then if they do I could use a repeat that many times to delete the last character. I was thinking there might be a faster or at least smaller way to write the code. Would a regex be better and if so how do you write the regex properly?

Another problem with this approach is that there may be other cases where the letters are in the string, and have a cr after them. All of the cases would be removed, not just the last one.

Re : Speed
All right, the permutations. Thanks for the responses. My findings so far : Mark wrote : -- In addition, you're losing much of the speed of the repeat for each loops by embedding a repeat with loop at the deepest level (and in addition you're making an unneccsary extra copy of tLine each time through the slowest loop): repeat for each line tLine in TempPerms1 repeat with y = Index down to 1 put tLine into Temp put newElement comma before item y of temp put Temp cr after TempPerms5 end repeat end repeat Something like this should be faster (do this for both upper and lower halves): repeat for each line tLine in TempPerms1 repeat for each item tItem in tLine put tItem comma after TempPerms5 end repeat put cr into char -1 of TempPerms5 end repeat -- Mark, I cannot get your improvement to work. I think there is something missing or maybe I am overseeing something. The inner loop in your script is equivalent to : put tLine into TempPerms5. The total result from the inner outer loop is the same as : put TempPerms1 into TempPerms1 As a total result of the complete script I always get (no matter what the input is) : 1,2 cr 2,1 In my script, I need to ' put tLine into Temp' in every time I pass the inner loop, to renew Temp with tLine. Otherwise I change tLine all the time in the inner loop. In every round in the outer loop, I step the new element (e.g. 3) through all possible positions in tLine (e.g. tLine = 1,2 1,2,3 1,3,23,1,2 ) . Then I go on and do the same with the next element (4 in this case) for each newly formed line (1,2,3 etc). Dick wrote : The Wikipedia entry for permutation says the fastest algorithm for generating permutations is Heap's algorithm. Quite interesting. I still have to understand what's happening completely, but I implemented you LC translation of the Heap algo. And it runs on my system a bit over 2 minutes (165732 millisecs) for 10 elements. To my surprise, my old algo does it in 7515 millisecs. I could improve on that by using chars instead of items (7465 millisecs). Another improvement I could make was by only calculating the upper half of the permutations (all the ones that start with 1,2,) and then copy them and swap the 1's and 2's. This gave as result only 5597 millisecs for 10 elements. I am a bit at a loss, as I would be surprised if my way would be like 25 times faster than the fastest known algorithm. Did I make a mistake in implementing Dicks code (although Dick also reports 2 minutes to do the job, as my way does it in 5.6 secs). What is happening here. I even suspect, that I can improve more on my improved way (by only calculating half of the perms and swapping the 1's and 2's. I might apply that principle more (like only calculating 1/4 of the perms and do some swapping, or even better). I will look into that later. --- Kay wrote : I obtained a 10% speed increase by changing this: repeat with n = 3 to 10 to this: put 3,4,5,6,7,8,9,10 into nList repeat for each item n in nList I haven't been able to try this, but it is very interesting in general. That even such short lists produce such a difference in speed in repeat with or repeat for. I thought that only counted for longer lists. very enlightening though. Thanks. --- Geoff : looks promising. It is in the ballpark where my alto seems to be. I will get back to you letter when I have had a good look and test at your script. New idea : I was hinting at a way of producing permutations in the case that there are duplicate elements in the input. F.i. 1,1,2,3 only gives 12 permutations instead of 24 for 1,2,3,4 as input. Before I calculated all the possible permutations and deleted the duplicates afterwards. I found that if I move the removing of duplicates to an early stage (as early as possible), the speedup is enormous.

I can edit the field and then immediately click the button, but the 'closeField' doesn't fire unless I make it do so explicitly, for example with a 'returnInField' handler, or if the whole stack loses focus and then gets it back.

Re: Speed
There are significant differences in speed between 5.5 and 6.6. Not so much in deriving the permutations as in displaying the results in a field. To see this run this in the message box: go url https://dl.dropboxusercontent.com/u/47044230/PermutationSpeed3.rev” (Does this only work in LC 6 and up?) To see the difference in earlier vs of RR you will have to open it in 6.0 and then save it as legacy. The difference is significant. It takes about 3 sec to run and display the permutations (using Geoff’s code) and display them in a field in 5.0, but about 30 sec in 6.0 Almost all of that difference is in the display. It takes only about 1 sec to put the permutations into a variable.

The general permutations function P only works with up to 10 items. It wouldn't be too hard to extend beyond that, but it would sully the very nice (IMHO) use of single digits to store the permutations. 2. The items to be permuted cannot contain the digits 0-9. This could also be worked around by using different characters for the permutation routine, but making it bombproof would be harder than that. gc function P N -- returns all the permutations of the digits from 0-N -- only works to N = 9!!! if N = 0 then return 0 cr put P(N - 1) into T repeat with i = 0 to N - 1 put T into T2 replace i with N in T2 replace cr with i cr in T2 put T2 after R end repeat replace cr with N cr in T return R T end P function PLines L -- returns comma-delimited lines containing -- all the permutations of the lines in L -- The lines in L cannot contain any digits from 0 to -- the number of lines - 1 put the number of lines of L into N put P(N - 1) into R repeat with i = 1 to N replace i - 1 with (line i of L) comma in R end repeat replace comma cr with cr in R return R end PLines ___ 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: OpenField mystery
That's been an issue on Macs forever. If you're in a field and then click a button, the field doesn't lose focus so no closeField is sent. I believe the way to get round it is to focus on nothing in the mouseUp code of the button (or the mouseDown).

I can edit the field and then immediately click the button, but the 'closeField' doesn't fire unless I make it do so explicitly, for example with a 'returnInField' handler, or if the whole stack loses focus and then gets it back.

Re: Android LiveCode stack player
If I understand what you're after (loading a remote stack?), maybe this will give you some ideas: http://runtime-revolution.278305.n4.nabble.com/Using-DropBox-for-Faster-Mo bile-Development-td4380386.html This isn't limited to DropBox obviously -- you can set up your launcher to load stacks from any URL. And you can load stacks saved as local documents. With published apps on iOS, there's always the question of what Apple will permit. Technically, they say no loading external code, but launching web pages with javascript and other web technologies is fine. Hopefully we'll have a clearer way around this once the HTML5 stuff is in place.

Re: delete end chars
I still can’t get it to work for some reason. And the first regex one ends up leaving me the letters that I wanted to delete instead of leaving the other part. After getting the others to work in a new stack I tried them in the script I needed it for and the only one that would work is the one Colin Holgate wrote. It seems the ones that used “the text” int the script might need to refer to a field and not a variable so I re wrote the script to use a field and it still did not work. I think it might be due to the place in the script I needed it is nested deep\ in some repeat commands. Once again thank you and everyone else for the help.

There isn't much in it and both scale well. If you'd like to test, create a new stack, one button and in the btn copy the below script which is one mouseUp handler and one Function fRandomInRange. The script will ask you how long you want your test string to be and how many times to you want to repeat the search. The default values of a string 100 chars long searched a million times (repeated 4 times) takes just over a second so don't be worried about starting with the default values. The search is repeated 4 times, 1st it does Colin's search, then it does Peter's search and just in case there is some kind of advantage/disadvantage regarding being first, I do Peter's search again and end off with Colin's. When run the message box should end up with something like this: For a random string of 100 chars long. Searched 100 times. Colin's 1st run: 362 ms Peter's 1st run: 349 ms Output Identical Peter's 2nd run: 351 ms Output Identical Colin's 2nd run: 356 ms Output Identical BE MINDFUL OF LINE WRAPS on mouseUp ask How many characters do you want in your random string with 100 titled Enter a Number put it - 3 into tAnswer put For a random string of tAnswer + 3 chars long. cr into msg repeat tAnswer times --generates a number between 32 90 and turns it into an ASCII char put numToChar(fRandomInRange(32,90)) after tData end repeat --so we know that the data contains the string to be found put ABC after tData put ABC into tFind ask How many times do you want to repeat the search with 100 titled Enter a Number put it into tAnswer put Searched tAnswer times. cr after msg put the millisec into tStart --Colin's 1st repeat tAnswer times put offset(tFind,tSearch) into tOffset if (tOffset = the number of chars in tSearch - the number of chars in tFine + 1) then put char 1 to tOffset - 1 of tSearch into tFound put tFound into tColin1st end if end repeat put the millisec into tEnd put Colin's 1st run: tEnd - tStart ms cr after msg put the millisec into tStart --Peter's 1st run repeat tAnswer times if (matchText(tSearch,(.*) tFind $,tFound)) then put tFound into tPeter1st end if end repeat put the millisec into tEnd put Peter's 1st run: tEnd - tStart ms cr after msg if (tColin1st = tPeter1st) then put Output Identical cr after msg else put ERROR! cr after msg end if put the millisec into tStart --Peter's Again repeat tAnswer times if (matchText(tSearch,(.*) tFind $,tFound)) then put tFound into tPeter2nd end if end repeat put the millisec into tEnd put Peter's 2nd run: tEnd - tStart ms cr after msg if (tPeter2nd = tPeter1st) then put Output Identical cr after msg else put ERROR! cr after msg end if put the millisec into tStart --Colin's 2nd run repeat tAnswer times put offset(tFind,tSearch) into tOffset if (tOffset = the number of chars in tSearch - the number of chars in tFine + 1) then put char 1 to tOffset - 1 of tSearch into tFound put tFound into tColin2nd end if end repeat put the millisec into tEnd put Colin's 2nd run: tEnd - tStart ms cr after msg if (tPeter2nd = tColin2nd) then put Output Identical after msg else put ERROR! after msg end if end mouseUp FUNCTION fRandomInRange pLower, pUpper return random(pUpper - pLower + 1) + pLower -1 end fRandomInRange ___ 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: Population puzzle
OK - I¹ll take the bait although elegant algorithms definitely aren¹t my forte. As a result this is probably a very half-baked and inefficient solution to the problem but it seems to work and doesn¹t have to resort to recursion (which I can never get my head around) to generate the starting combinations. Instead I just repeatedly randomise the order of the items and sum them in that order until I get the required value.

Thanks for checking this out Kay. As you said, there's no practical difference between the two solutions but it's good to know that regex is pretty fast (at least in this case) since it tends to get a bad rap when it comes to performance.
