Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	I think i got a solution - just trying to get it to verify with Jen`s checker thingy ... something is broke somewhere - prob my routine - highly HIGHLY un-optimized at 800+ chars ... Jens - can we use the bsort routine included in the checker ? [ 19. December 2002, 19:37: Message edited by: Shawn ]

All functions required for the decoding must be placed inside the appropriate section of the script. _________________________ Home page: http://www.kixhelp.com/hb/

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Jens, Haven't dug deep into your checker or anything, but shouldn't this line here: case $sEncoded==$sDecoded be like this: case $sSource==$sDecoded -Shawn

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11164 Loc: Boston, MA, USA	Shawn: Yes, you're right. I will correct this and post updated code both in the ZIP package and the top post in the thread. I also cleaned up those long lines a little bit. _________________________ There are two types of vessels, submarines and targets.

Sealeopard Sealeopard KiX Master Registered: 2001-04-25 Posts: 11164 Loc: Boston, MA, USA	The validation routine has been updated due to a bug that Shawn found. Both the ZIP package and the posted code have now been corrected. BTW, if you'd like to post official results then you can use the kixgolf_bwt.txt file that is created in the script directory. Ultimately, this file will contain some info about the Kixtart process that ran the challenge. The idea is to create some kind of weighted average of keystrokes, running time, and memory usage to create the final score. This way somebody might be able to achieve a better score by e.g. optimizing memory usage but using up more keystrokes. This might make it more interesting. Comments on this idea are welcome. _________________________ There are two types of vessels, submarines and targets.

It works for all of the input strings. Now it's time to start chopping it down. _________________________ Eric

maciep maciep Korg Regular Registered: 2002-06-14 Posts: 947 Loc: Pittsburgh	Yeah, it works for all of them. I just didn't want to display the results from the longer ones because well...they're long. But there's still some trimming to do. _________________________ Eric

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	I would like to propose a recommendation here - not sure if this is a requirement or not, but I think it is ... The Checker should make the following setting: setoption("casesensitivity","on") I believe (and correct me if im wrong) but this has to be done to get consistency across diff versions of sort routines ... it ensures that a series of mixed-cased letters are in proper order. Currently, bsort is NOT case sensitive so depdending on the string, you could have a series like this: mmmMMmmm then if you change the string slightly (add chars etc) the series could flip for no good reason: MmmmmmmM The mix of upper and lower is random ... if you actually dump the sorted string for minor variations of strings, might see it. Anyone have any comments ?

cj cj MM club member Registered: 2000-04-06 Posts: 1102 Loc: Brisbane, Australia	Maybe we could ask Ruud to see if there is something that KiXtart does internally that would be suitable for a KiXgolf score. It could be an undocumented macro like @KIXGOLF or disguised as something legit like @COMMANDSUSED maybe? cj
