Re Excel VBA CombinationsPermutations
Hi AndrewWelcome to the board
You want to calculate the Power Set of a Set
You can try this code
Code
Option Explicit PGC Oct 2007 Calculates a Power Set Set in A1 down Result in C1 down and accross Clears CZSub PowerSet()Dim vElements As Variant vresult As VariantDim lRow As Long i As Long vElements = ApplicationTranspose(Range(A1 Range(A1)End(xlDown)))Columns(CZ)Clear lRow = 1For i = 1 To UBound(vElements) ReDim vresult(1 To i) Call CombinationsNP(vElements i vresult lRow 1 1)Next iEnd Sub Sub CombinationsNP(vElements As Variant p As Long vresult As Variant lRow As Long iElement As Integer iIndex As Integer)Dim i As Long For i = iElement To UBound(vElements) vresult(iIndex) = vElements(i) If iIndex = p Then lRow = lRow + 1 Range(C amp lRow)Resize( p) = vresult Else Call CombinationsNP(vElements p vresult lRow i + 1 iIndex + 1) End IfNext iEnd Sub
Test
- Write a b c d in A1A4- run PowerSet
A B C D E F G
1 a
2 b a
3 c b
4 d c
5 d
6 a b
7 a c
8 a d
9 b c
10 b d
11 c d
12 a b c
13 a b d
14 a c d
15 b c d
16 a b c d

Re Excel VBA CombinationsPermutations
Hello
Im looking for the same thing except for permutationsie orderdoes matter so for 3 s or letters I will get 3^1 + 3^2 + 3^3answers or 39 But just like his original question I dont know howmany Ill have to start with
Thanks

n + n^2 + n^3 + + n^n
This is a geometric progression the total is
n (n^n - 1) (n - 1)
In the case of 3 elements the total is
3 (3^3 - 1) (3 - 1) = 3 26 2 = 39
The code is similar to the PowerSet but simpler as now you simply
loop through all the values
Insert in a module and run
Code
Option Explicit PGC Dez 2009 Permutations of N elements taken 1 to p at a time Set in A1 down Result in C1 down and accross Clears CZSub PermutationsN_1ToP_R()Dim vElements As Variant vresult As VariantDim lRow As Long i As Long vElements = ApplicationTranspose(Range(A1 Range(A1)End(xlDown)))Columns(CZ)Clear For i = 1 To UBound(vElements) ReDim vresult(1 To i) Call PermutationsNPR(vElements i vresult lRow 1)Next iEnd Sub Sub PermutationsNPR(vElements As Variant p As Long vresult As Variant lRow As Long iIndex As Integer)Dim i As Long For i = 1 To UBound(vElements) vresult(iIndex) = vElements(i) If iIndex = p Then lRow = lRow + 1 Range(C amp lRow)Resize( p) = vresult Else Call PermutationsNPR(vElements p vresult lRow iIndex + 1) End IfNext iEnd Sub
Ex for 3 elements
A B C D E F
1 a a
2 b b
3 c c
4 a a
5 a b
6 a c
7 b a
8 b b
9 b c

Re Excel VBA CombinationsPermutations
Hi All
This method PowerSet to work the combinations out is certainlyreally impressive
Is it possible to get the PowerSet Code adjusted so it alsoconsiders its own velements
I mean when running the code based on A and B and C
It will returnA B C A B A C B C A B C
I need it to return
A B C A A A B

A C B B B C C C A A AA A BA A CA B BA B CA C CB B BB B CB C CC C C
At the moment I can get the desired result by writing eachelements 3 times ie
AAABBBCCC
Once I have the results (by running the powerset code) I removeall the duplicate rows from the results (using excel removeduplicate)
The method works fine until I start increasing the number ofletters simply because excel will not handle so much data Themust be a way to do this without duplicating the elements thenremoving duplicates
Please helpThanks

Re Excel VBA CombinationsPermutations
Hi Again
What would be the formula to work out the results of CombReptbased on given no of elements
Say I have 2 elements I need to know (before I run CombRept)how many rows of data will contain 1 element (=2) how many rows of data will contain 2 elements (=3)
Say I have 4 elements I need to know (before I run CombRept) how many rows of data will contain 1 elements(=4)how many rows of data will contain 2 elements(=10)how many rows of data will contain 3 elements (=20) how many rows of data will contain 4 elements (=35)
The build-in COMBIN does really tell the that
Thanks

Re Excel VBA CombinationsPermutations
Hi All
This method PowerSet to work the combinations out is certainlyreally impressive
Is it possible to get the PowerSet Code adjusted so it alsoconsiders its own velements
I mean when running the code based on A and B and C
It will returnA B C A B A C B C A B C
I need it to return
A B C A A A B

A C B B B C C C A A AA A BA A CA B BA B CA C CB B BB B CB C CC C C
At the moment I can get the desired result by writing eachelements 3 times ie
AAABBBCCC
Once I have the results (by running the powerset code) I removeall the duplicate rows from the results (using excel removeduplicate)
The method works fine until I start increasing the number ofletters simply because excel will not handle so much data Themust be a way to do this without duplicating the elements thenremoving duplicates
Please helpThanks

Re Excel VBA CombinationsPermutations
Hi Again
What would be the formula to work out the results of CombReptbased on given no of elements
Say I have 2 elements I need to know (before I run CombRept)how many rows of data will contain 1 element (=2) how many rows of data will contain 2 elements (=3)
Say I have 4 elements I need to know (before I run CombRept) how many rows of data will contain 1 elements(=4)how many rows of data will contain 2 elements(=10)how many rows of data will contain 3 elements (=20) how many rows of data will contain 4 elements (=35)
The build-in COMBIN does really tell the that
Thanks

Excel 2007 Excel Formula Excel Help VBA
n + n^2 + n^3 + + n^n
This is a geometric progression the total is
n (n^n - 1) (n - 1)
In the case of 3 elements the total is
3 (3^3 - 1) (3 - 1) = 3 26 2 = 39
The code is similar to the PowerSet but simpler as now you simply
loop through all the values
Insert in a module and run
Code
Option Explicit PGC Dez 2009 Permutations of N elements taken 1 to p at a time Set in A1 down Result in C1 down and accross Clears CZSub PermutationsN_1ToP_R()Dim vElements As Variant vresult As VariantDim lRow As Long i As Long vElements = ApplicationTranspose(Range(A1 Range(A1)End(xlDown)))Columns(CZ)Clear For i = 1 To UBound(vElements) ReDim vresult(1 To i) Call PermutationsNPR(vElements i vresult lRow 1)Next iEnd Sub Sub PermutationsNPR(vElements As Variant p As Long vresult As Variant lRow As Long iIndex As Integer)Dim i As Long For i = 1 To UBound(vElements) vresult(iIndex) = vElements(i) If iIndex = p Then lRow = lRow + 1 Range(C amp lRow)Resize( p) = vresult Else Call PermutationsNPR(vElements p vresult lRow iIndex + 1) End IfNext iEnd Sub

At the moment I can get the desired result by writing eachelements 3 times ie
AAABBBCCC
Once I have the results (by running the powerset code) I removeall the duplicate rows from the results (using excel removeduplicate)
The method works fine until I start increasing the number ofletters simply because excel will not handle so much data Themust be a way to do this without duplicating the elements thenremoving duplicates
Please helpThanks

Re Excel VBA CombinationsPermutations
Hi Again
What would be the formula to work out the results of CombReptbased on given no of elements
Say I have 2 elements I need to know (before I run CombRept)how many rows of data will contain 1 element (=2) how many rows of data will contain 2 elements (=3)
Say I have 4 elements I need to know (before I run CombRept) how many rows of data will contain 1 elements(=4)how many rows of data will contain 2 elements(=10)how many rows of data will contain 3 elements (=20) how many rows of data will contain 4 elements (=35)
The build-in COMBIN does really tell the that
Thanks
