Suggestions for optimizing code?

[BrianTheLibrarian]

Hello, I'm generating recipes. I've generated a list of all possible combinations of 2, 3, 4 and 5 ingredients , and I have a list of all the percents that would be usable.  I've put together the following code, but with the 4s and 5s there are like 7 billion combinations. Is there a faster way to generate the combinations?

;78k elements
_FileReadToArray(@ScriptDir &"\all-percents.csv", $percents, Default, ",")
; 100k elements
_FileReadToArray(@ScriptDir &"\all-combinations.csv", $combos, Default, ",")

; text files that the soap recipes will be written to
Local $allRecipes = @ScriptDir & "\all-recipes.txt"

for $z = 1 to $combos[0][0]-1
    $arrayLen = 0
    ; this counts all the elements in the line of the array (2, 3, 4, 5) and stores the number in $arrayLen
    for $e = 0 to 5
        if $combos[$z][$e] = "" Then
            ; if it is blank, exit the loop
            ExitLoop
        Else
            $arrayLen = $arrayLen + 1
        EndIf
    Next

    Switch $arrayLen
        Case 1

            for $i = 0 to 0
                ; write the names & percents
                $write = $combos[$z][0]& "," & $percents[$i][0]
                FileWriteLine($allRecipes, $write)
            Next

        Case 2
            ; on the list of percents 1 through 380 is the list of 2 numbers that add to 100
            for $i = 1 to 380

                $write = $combos[$z][0]& "," & $percents[$i][0] & "," & $combos[$z][1] & "," & $percents[$i][1]
                FileWriteLine($allRecipes, $write)
            Next

        Case 3
            ; array elements that match the 3 number combinations that add to 100
            for $i = 380 to 3800
                $write = $combos[$z][0]& "," & $percents[$i][0] & "," & $combos[$z][1]& "," & $percents[$i][1] & "," & $combos[$z][2]& "," & $percents[$i][2]
                FileWriteLine($allRecipes, $write)
            Next

        Case 4
            ; array elements that match the 4 number combinations that add to 100
            for $i = 3801 to 23177
                 $write = $combos[$z][0]& "," & $percents[$i][0] & "," & $combos[$z][1]& "," & $percents[$i][1] & "," & $combos[$z][2]& "," & $percents[$i][2]& "," & $combos[$z][3]& "," & $percents[$i][3]
                FileWriteLine($allRecipes, $write)
            Next

        Case 5
            ; array elements that match the 5 number combinations that add to 100
            for $i = 23178 to 100673
                $write = $combos[$z][0]& "," & $percents[$i][0] & "," & $combos[$z][1]& "," & $percents[$i][1] & "," & $combos[$z][2]& "," & $percents[$i][2]& "," & $combos[$z][3]& "," & $percents[$i][3]& "," & $combos[$z][4]& "," & $percents[$i][4]
                FileWriteLine($allRecipes, $write)
            Next
    EndSwitch

hey

can you post an example file?

i actually dont get it - seems rly complicated for an easy function but i didnt really understand what you want   would help to understand it  

 

 

EDIT: I mean there are so much undefinied numbers i actually don't know where they come from in your

For  
next

loops

u can change :- 

Local $allRecipes = @ScriptDir & "\all-recipes.txt"

to

Local $allRecipes=fileopen( @ScriptDir & "\all-recipes.txt",2)

and add fileclose to the end of the script :-

fileclose($allRecipes)

Sure so for example you would have the letters A through L and all permutations of them in. So you would have:

a,b
a,c
a,d
....
a,a,b
a,a,c
....

and so forth all the way through the 5 combinations of the ingredients.  Now the percent file has all the percents in increments of 5 like

5, 95
10, 90 etc all the way up to the 5 combinations of percents.

The script goes through and merges them together. So the final output would look like

a, 5, b, 95
a, 10, b, 80
etc...

and once it goes through all the 2 number combinations for the 2 letter combinations it repeats it for the next set of letters. Then the 3 letters / 3 numbers, 4 letters / 4 numbers, 5 letters/ 5 numbers.

a, 5, c, 95
a, 10, c, 80
...
a, 5, d, 95

which the above script works, except that it is going to take something like 2 months running 24/7 to generate all the combinations.

Have you tried @Network_Guy suggestion ?  It's going to save you a lot...

I just did. Wow..... yeah major improvement.  Thanks a TON @Network_Guy!

BrianTheLibrarian,

Just why are you doing this massive exercise in combining "ingredients"? What exactly are you going to do with this multitude of different "recipes"?
