Matrix Combinations And Permutations
Mar 15, 2007
i've got 2 numeric numbers one in each cell. These numbers indicate Maximum occupancies for a hotel room...
Maximum Adults Maxmium Occ
3 5
The Occupancy table looks like this
Adults Children Infants... so taking the above numbers the table should be built up like this
Adults Children Infants
1 0 0
2 0 0
3 0 0
1 1 0
1 2 0
1 3 0
1 4 0
1 1 1
1 1 2
1 1 3
3 2 0
3 0 2
3 1 1
etc...
so basically to room can have a maxium of 3 adults and 2 children equaling the maxium room occupancy.
i'm trying to create a function that will automatically do this and workout subsquent numbers below the maxmium but i can't get anywhere near the result i am looking for...

You will find a VBA Code for a PRIVATE example - displaying all 6 numbers combinations out of 10 (1-10).
My code displays them (in column "A") BUT What my question to you is - does someone have a General/Universal code to handle other kinds of combinations.
To my opinion, the usage of Nested (For-Next) Loops will not be the ideal solution - so maybe by using VBA Recursion ?

I must first thank the forums for the amazing help in making my life just a little easier, especially member "shg" for helping set up the VBA code to help me.
So I have a sheet to develop all possible combinations of units, the letters with their associated values above, as well as the maximum number of units possible. The user inputs a top value, this is followed by some subtraction leading to a working value with a tolerance level in which the sum of the combinations needs to remain within.
What my predicament is that while the VBA code in the attached book works to develop most combinations, when I input a small number such as 405, the combinations that arise are not complete. The results are shown in the attached workbook: show combinations of H and PP, but any human can read that there should also be 2 HN in the results, as the math add's up to within the tolerance level.

For Ex:- If there are three Items.. A B C and forming a group of 2
then the the total no of combinations would be permut(3,1) = 6...
I need this to be shown as follows depending on the no of itmes and no of group no=2 in this case...
Permuations & Combinations are as follows:
AB
AC
BC
CA
CB
BA

I own a custom print shop and I am trying to generate skus based on variables..Column A will only have one item (the product code), column B will have the sizes, Column C may contain more or less colors depending on what is offered for the shirt style, Column D hopefully can contain all the combinations. All this data will be in contained within one worksheet..
Column A
Column B
Column C
Column D
G200
S

I want to output every combination of a set of numbers. These permutations must include combinations that use only a few of the numbers as well as all eight...ie.
1,
1,2
1,2,3
as well as 1,2,3,4,5,6,7,8
The macro below is from
http://www.j-walk.com/ss/excel/tips/tip46.htm
This only produces combinations using every number. I'm not sure how this macro works but hopefully someone with better know how could run with it or break it down for me!
I only need to achieve this once but am pretty sure doing it manually will cause error and or madness
Dim CurrentRowSub GetString() Dim InString As String InString = InputBox("Enter text to permute:") If Len(InString) < 2 Then Exit Sub If Len(InString) >= 8 Then MsgBox "Too many permutations!" Exit Sub Else ActiveSheet.Columns(1).Clear CurrentRow = 1 Call GetPermutation("", InString) End IfEnd SubSub GetPermutation(x As String, y As String)' The source of this algorithm is unknown Dim i As Integer, j As Integer j = Len(y) If j < 2 Then Cells(CurrentRow, 1) = x & y CurrentRow = CurrentRow + 1 Else For i = 1 To j Call GetPermutation(x + Mid(y, i, 1), _ Left(y, i - 1) + Right(y, j - i)) Next End IfEnd Sub

I have a number 23753.2570, to be precise.
in another column, i have 400 rows filled with different numbers, from 1.4 to 23000,7840.
I need to find out all the possible combinations of which numbers from that 400 can make up 23753.2570.
so if my number was 40,000, and i had 4 cells with 10,000 in them, the outcome will be:
"There are 4 possible combination to your value"
then paste it into a new worksheet with the results
[cell1] = 10000 + [cell2] = 10000 + [cell3] = 10000 + [cell4] = 10000
Total = 40000
i found this code, but i tested it on the example above and it said "All Combinations exhausted" which they wasn't?
Sub findsums()
'This *REQUIRES* VBAProject references to
'Microsoft Scripting Runtime
'Microsoft VBScript Regular Expressions 1.0 or higher
Const TOL As Double = 0.000001 'modify as needed
Dim c As Variant

I've got what I think is a pretty interesting problem, not sure if it can be solved with Excel, and if not that's fine I'll think of something better but thought I would put it up here.
I have two lists, one of adjectives, one of nouns. I want somehow to generate every possible combination of the two. Eg:
List 1:
Adj1
Adj2
Adj3
List2:
Noun1
Noun2
Noun3
gives us:
'Adj1&Noun1', 'Adj1&Noun2', 'Adj1&Noun3', 'Adj2&Noun1' ... etc etc
Is there a way to solve this problem using a macro or a pivot table?
NB ideally i would like all possible combinations to include reversals. i.e. 'Noun1&Adj1' and 'Adj1&Noun1' etc.

I have two columns of data in a worksheet, and I need a third column that shows all of the possible combinations of the data in those two columns. For example:
A
A
AA
B
B
AB
[Code] .....
I don't need permutations so, for example, the third column should only give the combination "AB" and exclude "BA".

I was just wondering is it possible that a excel spreadsheet could find all the different combinations for these set of letters. Also i can only have 1 letter from each group per combination.
First Group ABCDE
Second Group FGHIJK
Third Group LMNOP
Forth Group QRST
Anyone know is this is possible to create?

I'm trying to figure out how to generate all combinations from a list
of N values in a column, let's say column A. In particular, I want to have all combinations of 2 values, 3 values, 4, ... up to 7 values. To give an example: Let's assume I have a list of only 3 values (1,2,3) for which I want to have all combinations of two values. In this case, the result would be 1,2; 1,3; and 2;3. The ordering of the values does not matter, i.e. duplicates should be eliminated.

I have a list for example:
apple
pear
grape
orange
i'm after some code that will create every possible combination of the list.
The examples i've found in the archives give all possible combinations of the same list in a different order
e.g apple, pear, orange, grape.......apple, orange, pear, grape.........apple, grape, orange, pear etc etc etc... THIS IS NOT WHAT I'M AFTER.
i'm after every possible combination starting right at the beginning with single words
e.g
apple
apple, pear
apple, pear, orange
apple, pear, orange, grape
pear, orange,
pear, orange, grape
orange,
orange, apple
etc etc you get the idea..... but i do not want repititions like
apple, pear.........pear, apple.
apple, orange, pear ...........pear, orange, apple.

I need to figure out how I can get excel to write me a list of permutations / combinations for the Group (column a) and Item (column b) columns in the example. The group designates the items that should be inlcuded in the combination / permutation in Related Items (column c). I have thousands of lines to do this with so I need to figure a way to automate it. I have started the Related Items column which is the results I need output. If it could format it like this adding in the space between the rows as it outputs the answer that would be perfect. Anyone know how to do this? I've found many answers, but none that have 2 columns with separate grouping within the column.

Using VBA, I wish to work out the inverse matrix of a large matrix (100*100), but keep getting the # Num! Error. I am using the minverse function. I have defined variable as "variant", does this give me the same possiblities in terms of number size as the variable "Double"?

What I am looking for is to select between 7 and 15 numbers in total, I want all the possible 6 digit combinations for this.
EG: if I choose 2,9,11,13,15,17&26, it would look something like this
2,9,11,13,15,17
2,9,11,13,15,26
9,11,13,15,17,26
And so on.
If I chose more numbers (10) 1,2,3,4,3,6,7,8,9,10 it would start something like this
1,2,3,4,5,6
1,2,3,4,5,7
1,2,3,4,5,8
1,2,3,4,5,9
1,2,3,4,5,10
And so on.
Please remenber I would like to be able to secelt between 7 and 15 number and be given all the possible combinations.
I would like it to be in one sheet but if that can not be done on as many as it takes.
It would be good if I could just type the required number into A1,B1,C1 and so on and they just gave the combinations required.

For a table like the one below produced for the sake of example (actual is much much bigger) I want to make it list rows that are true for a certain column for a certain variable in the matrix. So for say water terrain, which types of activity can I do i.e. swimming. Or for Offroad the activites which I can't do i.e. Run and Swim.
ActivityWaterRoadOffroad
Jog nym
Run nyn
Walk nyy
Swim ynn
y=yes
n=no
m=maybe

I'm sure I should be able to do this but my brain is out of gear today!
Can someone tell me how I can create a list of every 5 letter permutation using only letters (A-D).
I also need to do the same for 4 letter and 3 letter, again using A-D.
Would prefer to do it without VB but if this is the only way......

I am creating a class of permutations. The problem is that there are many ways to describe what a permutation does. for example.
Dim aPerm As New clsPermutation
Dim bPerm As New clsPermutation
aPerm.DoesTranspose(2,3) : Rem aPerm.Action({a,b,c}) = {a,c,b}
MsgBox (aPerm Is aPerm.Inverse)
I want the message box to return True. But since aPerm and aPerm.Inverse are different instances of clsPermutaion, it returns False. (.Inverse is a read-only property that returns a clsPermutation.). What I would like to do is have a collection, myPermutations. When I specify the action that aPerm does, I would like
1) if nothing in myPermutations does the same thing as aPerm, then add aPerm to myPermutations.
2) if something (xPerm) does the same thing as aPerm, then
Set aPerm=xPerm
so that "xPerm Is aPerm" returns True.
The problem I have is that in the class module,.....................

I need VB codes for an activity in excel. Im trying to create an example file for the suppliers to enter keywords (Search keyword) where it should generate different formats of the search (WORDS) and its case sensitive. Suppliers would be typing the keywords in A2 and it should generate the Permutations horizontally against the keyword (B2 C2 D2 E2 etc). Let me know if you need more clarifications.
Example given below and also attached the file for your reference.
New Keyword – Singular Proper Case
Singular-PR
Singular-LC

Simple permutation problem that will most likely requires nested loops. I need a list of every possible permutation of words in a row broken out by column. Order does matter and not every row has the same number of words in it. I have attached a sample worksheet with a sample table and then the needed output format.

Is there any way to determine all possible unique combinations (or sets) of any 3 strings in a table? I need to make a master set list from a list of strings which could be over 100 elements long.
Once I have a result set, I need to get rid of any groups which have a value contained in another group.
Example:
cells A1 through B100 contain:
Item1 45
Item2 50
Item3 98
...
Item100 75
Result set would contain groups of any 3 item combinations where the corresponding "B" value is within a certain range (between 40 and 80), while also trying to create sets with the lowest possible sum (placed in the 4th column) of the 3 numbers.
One possible combination would be:
Item1 Item2 Item100 170
etc...
I need to list all possible combinations, without re-using an element from a previous (lower sum) combination that matched the criteria.

I have trying to assign cards to respondents to view. I have 16 cards total which are grouped in sets of 4. Each set (of 4) is given a color, (red, green, blue, and yellow). Each color has a 4 different shades (S1, S2, S3, S4) so I have the following 16 cards:
1: Red_S1
2: Red_S2
3: Red_S3
4: Red_S4
5: Green_S1
6: Green_S2
7: Green_S3
8: Green_S4
9: Blue_S1
10: Blue_S2
11: Blue_S3
12: Blue_S4
13: Yellow_S1
14: Yellow_S2
15: Yellow_S3
16: Yellow_S4
I will have a total of 10 respondents giving their opinions who will each see 5 of the cards, randomly. Each respondents must see each color at least once (given that 5th card will be a repeated color). Each card must be tested 3 times (given that the 2 additional cards can be any of the cards).
If there a function or cell code that I can write so that I can allocate the card #s (1-16) across my 10 respondents?

I need to work out a formula which will work out 48 permutations.
There are three headings: Impact, Probability, Risk Category:
ImpactProbabilityRisk Category
VHM = 1
VHH = 1
VHVH = 1
HH = 1
HVH = 1
VHL = 2
HM = 2
MH = 2
MVH = 2
HL = 3
LVH = 3
MM = 4
LH = 4
ML = 5
LL = 5
LM = 5
The formula I need is: if Impact is "L" and probability is "M", then return answer = "5".
The thing is - there are 48 possible answers - and im not sure what formula you could type into 1 cell - which would answer this.

I have a set of numbers 1-24, what I would like to have is to list every 4 set combination of 24 numbers. I believe this is 10626 combinations. I would like the combinations to display in seperate cells.
For example: Rows 1, column 1, 2, 3, and 4 would look like 1 2 3 4. No two numbers can be the same within that row. Row 2 would have 1 2 3 5 and so on untill all possible combinations are exhausted.
How does one do something like this within excel?
Also, I would like to be able to change the value of 24, so instead of entering 24 I could say I have a set of 32 and want a list of 4 or 3 permutable combinations. I want to be to make this as custom as possible.

THREAD SOLVED...and very well too
I need to find all 3, 4 and 5 letter permutations based on 5-8 musical notes as input. FYI the permutations will be chords. i.e. C, D, E, F, Ab, Bb, B as an input musical scale input would yield
All three note combos :
C,D,E
C,D,F
C, D, Ab
....
all 4 note combos
C,D,E,F
C,D,E,Ab
all 5 note combos
C,D,E,F,Ab
C,D,E,F,Bb
...
I'd like to structure the sheet as having 12 columns (1 for each note within an octave) with the combo placed under the right column i.e. C goes in 1, Eb in 4.
