Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Just an update where i am. I've got two algorithms in the works ... a really slow one and a really fast one. The numbers are like follows: slow one: 232 fast one: 267 The fast one does the big string in under half a second. The slow one does the medium string in like 30 minutes or something - can't even bear to wait for it to finish [ 24. December 2002, 07:11: Message edited by: Shawn ]

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	Sounds like your really stupid one is the same one I am using with a score of 231. I am now working on a super fast one (I hope). Still trying to understand what I am doing but it looks promising. _________________________ Home page: http://www.kixhelp.com/hb/

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Ive been staring at this fast one for over two days now - i've found a way to shave a couple more bytes, but I think a kixtart bug is getting in the way. hopefully, once the contest is over we can raise bring this Ruud attention. more importantly, not too sure which script I want to stare at for the next few days ... the smart one or the stupid one.

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	I think my stupid one is pretty tight at 231. I can't seem to find any way to trim it. The smart method seems have a requirement that necessitates more code than the stupid way. [ 24.

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	Well - I finally now understand your comments re: the slow sort vs the fast sort Whats your time for the processing string #2 (len=139) ???

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	I can't find any saved data on that one. Sorry. I am currently executing the 749 byte string using the slow sort on 4.20B1 to see how long it takes. _________________________ Home page: http://www.kixhelp.com/hb/

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	Yeah, I have never heard my fan stay on for a couple minutes let alone hours like now. At least I am finnally using the potential of the CPU. I new there was some reason I bought a faster computer. [ 24.

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	The 139 byte string took 1336181 msecs on a 500mhz P3 ... think thats about 22 minutes ... i got that right ?

Why didn't I see that before. Now you have the lead. Our code must be identical. _________________________ Home page: http://www.kixhelp.com/hb/

Shawn Shawn Administrator Registered: 1999-08-13 Posts: 8611	I figured you would have went down to 228 because you have (had) a byte edge ... what happened to that ?

Still looking for the wayward byte. [ 24. December 2002, 08:26: Message edited by: Howard Bullock ] _________________________ Home page: http://www.kixhelp.com/hb/
