Permitted Permutation/Combinations With Some Rules

May 25, 2007

I have found this very challenging, and have really confused my self on how to systematically approach this. I have the user enter the value in the black highlight boxes, some subtraction produces a base value, the user may also enter the tolerance of the working value (base value), effectivlly giving rise to a small range to generate the permutations from.

What I would like to do then is find all permutations of the inventory (letters in the sheet) with their corresponding values right above them to the small range determined via the user (working value and tolerance). There are also quantity limits for each item. There four basic rules that need to be adhered to:

1) Permutation can't have both S and PP, so one or the other
2) Sum of H and HN must be greater or equal to sum of S and PP
3) H or HN or both must be present, so their sum cannot be zero
4) If HN is less than or equal to 2, and H is greater than 2, then NA and NG must equal 0.

Can this be done in Excel? Using the digits 0,1,2,3,4,5,6,7,8,9 create all the permutations/combinations with limits on some of the digits. The digits 0,7,8,9 can only be used a max of 3 times in any one permutation/combination, digits 2,3,4,5,6 can only be used 4 time in any one permutaion/combination, producing a 5-digit string.
Example of expected results.
0 1 0 2 7

Bulk Permutation Of Words

Jan 27, 2008

i have read through all threads about permutation, and also a few others. I if I were an Excel Pro I would probably have been able to come up with a solution to my problem based on all the suggestions made, but unfortunately it is (still) all a bit too complex for me.

The problem:

I have between 2 and 5 lists of words, each list in one column:

Column A

blue green

Column B


Column C

for women
for men
for girls
extra large
for boys
one size fits all

Column D

Create A Permutation List

Feb 20, 2008

I have several items that I would like to combine, lets call them characters A, B, C, D, E

Each character is situated in a different column, next to each other. Below, I would like to create a list of all possible combinations of these characters. The sequence is not important and each row should contain a unique combination of characters.

I have counted 31 combinations for the ABCDE set, namely

1 for ABCDE
5 for A, B, C, D, E each
5 for choosing 5 unique sets of four from a set of five (5!/(4!*(5-4)!)
10 for choosing 10 unique sets of three from a set of five (5!/(3!*(5-3)!)
10 for choosing 10 unique sets of two from a set of five (5!/(2!*(5-2)!)

To complicate matters, I have several other character strings where I would like a list of combinations. For example A, B, C, D, E, F, G, H 9 (a longer set).

By the way, each combination should be spread accross several columns (e.g. one colum per character, see the question marks in the table below) ....

VBA Not Following Consistent Rounding Rules?

Jun 13, 2014

This Subroutine:

[Code] .........

Seems to behave differently each time it is called from my main Loop. As an example the first loop finds:
TotalTubes = 6
TubeRows = 4
TopRowTubeCount = 2
Where 6/4 = 1.5 and is rounded up to 2

The controlling variable in my code for Length is TopRowTubeCount and it is a Public Variable Dimensioned as an Integer

However on the next loop it finds:
TotalTubes = 210
TubeRows = 4
TopRowTubeCount = 52
Where 210/4 = 52.5 and is rounded down to 52?

I even used the round function for the TopRowTubeCount calculation and the erratic behavior continues.

Some Cells Not Following Protection Rules

Aug 5, 2006

I have set all cells in a worksheet to be protected. I then selected specific cells that are not protected. The problem is that cells A11:D29 except C13:C14 do not follow the protection rules in that I can edit them (but when I right click, I cannot format, just like they're protected). These cells are NOT part of the group that was selected to be unprotected. When I unprotect the sheet and check the protection setting for these oddball cells, it shows as protected. All other protected cells do not allow entry (which is what I want).

Setting Rules For Multiple Of Number?

May 29, 2014

I have started to use excel again because I need to create a spreadsheet for maintenance hours done on a vessel. The problem I have right now is, how to set a rule to allow only certain multiple of a particular number to appear. For example,

I have a initial cell value where I have to manually insert the total number of hours that have gone by in the vessel. Let us say that this value is 500 hours.

In another cell which is labeled, "Last Completed", it would have to read at how many hours this job was last completed.

I also have another cell which gives you the time interval before the job is performed again. This value is 250.

So if the current number of hours is 500, the last completed date should be 250. (assuming Maintenance was done at 0 hours and 250 hours).

How do I make it so that the "Last Completed" cell would read 250 until I hit 750 hours which at that point should read 500 Hours.

Different CONCATENATE Rules Depending On Cell Value

Using IF Function To Use Different Formulas Depending On Different Rules?

Nov 27, 2013

I have got to this stage with a formula but cannot understand why it isn't working:


If A2 equals 1, I want it to add 50 on to the smallest (earliest) date in C2:C5.


If A2 equals 2, I want it to add 50 on to the largest (latest) date

The formula just adds 50 on the smallest (earliest) date, whether A2 equals 1 or 2.

What am I doing wrong?

Delete Rows Based On Rules

Aug 21, 2007

I am trying to clear row with the following rules:

the last cell must not contain 0, if 0 delete entire row.
the first cell the the A row should be only three character long, if more delete entire row.

Now I managed to delete the 0 in the last cell and but cannot get the VBA to count the characters in the first row and if more than three, delete the entire row . I know to count the characters in a cell is done by Len(Rng.Value) , but getting the VBA right is alluding me .

the script is here,

Sub Del_rows_with_zero_in_column_of_activecell()
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
Const StartRow As Long = 1 'Row to Start looking at
Dim StopRow As Long
Dim Col As Long

Custom Rules For Sheet Naming

I want something strange but i guess you can do just about anything with excel these days if you ask around.

I want names for the sheets that are contained on a specific excel file that i have to be automatically generated accordingly to the following:

sheetname = runxyy_s=zz%

Where x is the lowercase letter of the word formed on the name of the first sheet of the workbook
and yy and zz are values stored on specific cells on the sheet,lets say yy is A1 and zz is H4.
