you bastard!

damn, I made myself a quicker engine and realized that it skipped a lot of stuff.

jens, I think we could include the execution time in the engine to compare...

Execution time varies based on hardware used and also the specific algorithm. There are three distinct algorithms that can be used to solve this particular problem. One can use each of the algorithms by itself or combine them to achieve greater accuracy.

Anyway, I'll make a modification to the scoring screen to include both the start and stop time of the runs instead of just date/time. However, take those times with a grain of salt. I will post an updated package later today once I'm back home as I have all the material at home.

Finally, though Patrick posted the first working version, the algorithm can still be improved. I'm waiting for the person to completely optimize all CDs [Big Grin]

Mine wasn't a real algorithm...

Since much of improvement, I'm going for 'Perfect CD Sorter'...

Patrick:

A) Your routine worked!
B) You beat Joeel!

What else can you ask for? [Smile]

Did you download the ZIP Package? That one contains a ready-to-run script and UDF. The UDF output, as specified in the README, is a comma-delimited string of the song numbers, e.g. '1,2,3' if your are using songs 1, 2, and 3 of a particular CD.

Fix( )

Action: Removes the fractional part of a number and returns the resulting integer value.

Syntax: Fix (expression)

Parameters: Expression

Any valid numeric expression.

Returns: Variant of subtype Integer.

Remarks: If the number is negative, Fix( ) returns the first negative integer greater than or equal to the number. For example, Fix( ) converts -6.3 to -6.

See Also: Abs( ), Int( )

oh...
damn, if I would have known that the run time of the script is this long, I would have done some improving of the code before executing it...

already been running about 1,5hours...
think I'll go to bed and post the result once it finishes... hopefully tomorrow.

Going for "Perfect" really eats up my servers CPU [Wink]

First CD took about 10 mins with a total cd time of 44.9999

Talking about optimization...

Is there any reason that the sort is called 100 times?

Is it to deter brute force solutions?

Yeah bummer indeed.

I was expecting the script to have finished this morning based on the time it took to resolve CD 1, and was surprised that it wasn't. Then I spotted the 100 iterations.
