Score = 235

For the 749 length string, decoding part takes about 10 seconds (733mhz)

I just double-checked my 226 and it ran fine ! Theres no way im running the biggy on this though ...

maciep - do you have a slow 226 or a fast 226 ?

[edit] re-read the thread - guess that would be a fast 226 - Howard, looks as if both you and I are going to need a new hat [Frown]

My slow method has now been running on the 749 byte string for 18+ hours. [Frown]

220 [Eek!] My brain has been fried switching back and forth on these two methods. Can I do this in Perl please [Wink]

I haven't given up yet.

Im a little confused about how we are going to "validate" a winner. The checker script uses a "random" string ... which one of those strings are we going to use to valid the winner ? If the winner takes two days running time to validate against the biggest string - whats that going to mean ?

Well, it's time to do the holiday thing. I'll jump back into this in a couple of days. Try to keep those scores nice and high for me.

Last Run:

Score = 223

Stil not in contest [Wink]

I have implemented the 'hard' way = 'fast' way

This brought my score up to 586 (more than double the smallest in contest [Eek!] )

But the time for the executing the long string (749) got down to 4 secs. instead of X hours

I noticed a post from maciep:

It would be nice to have a third round of golf (Club house discussion [Smile] ), where the function-/variables-names where discriptive.

It would spare us all from trying to understand the brilliant code from the winner.

I use a lot of the ideas from the INI-write golf competition, BUT you have to participate to understand the problem/code fully.

25+ hours and still churning.

I cannot fathom how anyone can implement the fast process in less than 260 characters at this time. My fast process is currently around 270 characters. I am sure there are some things that could be improved upon, but the slow method employs less processes and therefore less code. How can the fast process be implemented in 226 characters? I'm still scratching my head how you Shawn got to 220.

Still scratching my head. [Confused]

Well, if its any consolation I don't think I can squeeze any more out of this 220 script - in fact since I really dont want to test it on the 700+ string - it might not even qualify as a valid score. Might have to start looking at yet another algorithm ...

Maybe we should have two prizes in this round ... one for the shortest script and one the fastest script ...

Well, I've tried just about everything I can think of to cut three more stokes off my score, but to no avail.

Decoding takes about 5 seconds on the large string input. (ver 4.20 and 730mhz)
