FromToTriggerrange26Stop-lossrange25Combination triggerlevelie: 4Combination stop levelie: 5Profit $10
How can I make "Solver" run a check on which combination of trigger and stoploss that gives the highest profit? The range is in two different cells, but I can't get it working. I guess that it's my lack of skills, and not "Solver" that isn't complex enough.
i have some data in array format and want to use that data in the solver. However, as per my understanding solver takes in only ranges. How can i use arrays directly? this is wht i am trying, but not working
entities = 1
spread = 3 + entities
ans = 5
SolverOk SetCell:=spread, MaxMinVal:="3", ValueOf:=ans, ByChange:=entities
I have a cell, D5, which is the sum of three other cells, A5 B5 and C5. (all currently empty). Cells A1 through C4 are filled with various numbers.
What I've been trying to do is use solver to say: Make D5 equal 200, do it by manipulating only A5 B5 and C5, and make it subject to the constraint that A5 must equal a value selected from A1:A4, and B5 must equal a value from B1:B4, and C5 ...etc. I have deliberately set it up so that there is only one solution.
I was doing fine until trying to create the constraints. How can I make a constraint that says "this cell" must equal "one of the following cells"? And if I can't do that, is there an alternate method of achieving the same result?
I'm doing a statistics workbook there I need to add untill the given value in the cell

I am currently using the .resize function to give a specific value to each cell within a range.
First of all, is it the most efficient way to do it?
If so, why am I getting error "Application-defined or object-defined error"
with this code :
Code:
ThisWorkbook.Sheets("Merge").Range(Cells(3, 2), Cells(4000, 2)).Resize.Value = "TEST"
I'm trying to write a formula that searches for the name of the column on one sheet, finds that column on another, then results in the column letter. So, ideally, if the first three columns in the first tab were "Team," "Name," and "Total," respectively, I just want a formula to search for "Name" and give me back "B."
I want to do this in case anybody ever moves the "Name" column, for example, from column B to column C -- so then it would search for "Name" again and change the range in the formula to "C" because that's where that data lives now.
Currently, I'm using it for a COUNTIF() function that is a very simple: =countif(indirect("'"&$A2&"'!K:K"),$B2), where A2 is the sheet name. The latter half of $B2 is fine -- but I would love to have a more complicated formula take the place of the range "B:B" in case the "Name" column ever got moved.
I have a list of sites and depending which site I select from my drop down box I want to retrieve that data from my full data sheet. How can I go about doing this?
View 3 Replies View RelatedI need a formula (or formulas) to give me the "coordinates" (Column & Row location) of a certain value in a large rectangular range. Intuitively this should be doable with a smart combination of VLOOKUP, HLOOKUP, INDEX, MATCH, ADDRESS and/or CELL functions (maybe in the form of "array formulas") but I can't seem to find the way...
Here is an example of what I need:
I have a large rectangular range (A10:F500), full of numerical values. Then in cell A1 I have one of the (many) values contained in the range, let's say, 3.14159. I need two formulas that give me the following:
a) A formula in cell B1 that tells me in which COLUMN of the range the value 3.14159 is located
a) A formula in cell C1 that tells me in which ROW of the range the value 3.14159 is located
If the range consisted of a single column (or a single row), this would be an easy INDEX and MATCH combination.... but I'm dealing with a *rectangular* range here...
I have to use use the solver to calculate something (a mean-variance framework).
I am using the solver to minimize a cartain cell (variance) by making two cells equal through (expected return) by varying 10 cells( weights of assets), but I have to repeat this for 500+ times (for different expected returns).
Someone told me that I could best use some sort of loop through VBA. But I don't have a clue how that works.
In 1 cell i need a forumla to give me a starting number and take one away each time a code or codes are dislayed in a cell range. Something like this
A1 = 23 days or any number days i needed
Cell range B1:C52
every time a selected 1 or 2 letter code appears in the cell range i want A1 to subtract 1 day from the starting number, i would need it to subtract half a day if one code appears ie HD, the codes may be P, OT, HD
I have a HUGE dataset (more than 1 million rows). I'm trying to find the optimum cell range size - 10 rows, 100 rows, 682 rows, whatever - for a SUM formula. (The formula would be in every row, looking down at the next n rows).
Is it possible to control the SUM cell range specified in a formula in cell (X) with a value in cell (Y)? In other words, the SUM formula in cell (X) would somehow refer to cell (Y) to determine the SUM cell range.
Ideally, I would like to then use Solver to find the optimal value for cell (Y).
Is this possible with just formulas? Or is VBA required?
I want to use solver program. But when solver "changes cells" i want it to trigger my pivot tables in the workbook. So i added the code to my worksheet:
Private Sub Worksheet_Change(ByVal Target As Range)
ThisWorkbook.RefreshAll
End Sub
So when a change occurs, all my pivot tables will get refreshed and my data will change. Is solver able to trigger this event while solving an optimization problem?
I am trying to drive Solver in Excel 2000 with a Visual Basic (version given as 9969) macro. SolverReset is observed, and SolverAdd puts the constraints in. But the SolverOK statement does nothing, so the SetCell and the ByChange windows stay empty.
SolverSolve is trying to do something, because the spreadsheet cell that should receive the return code from Solver gets an error value #VALUE! (The macro then stops, unable to process this entry.)
Solver is checked off ok in the References list in V.Basic.
The same macro, same spreadsheet, in the same Excel file, works fine on the other computer in my office with what I am told is a more recent version of Excel; i.e. this doesn't look like a coding error.
I wanted to see if I could use the solver to Solve Sudoku puzzles. I created the attached workbook. First it colors the numbers that are put in manually, which would be the starting puzzle. I have a generic one put in now. Then it finds which cells that are allowed to change. Then it is supposed to solve. It doesn't work. Run the Sheet1.SolvePuzzle Macro to see it not work. Is solver just not up to the task, or am I missing something?

I created a trendline and associated equation for some data plotted against Time on the x-axis displayed in MM/DD/YY format. The date for the data ranges from 3/27/06 thru 11/10/08.
The trendline equation is
F(x)=-6E-13x^5+1E-07x^4-.0087*x^3+329.1*x^2-6E+06*x+5E+10
The data actually crosses the y=0 line around 11/5/07, which is the data root
When I use Goal Seek, I got a zero root solution of 28154.98. When I convert this to the date format, it converts to a date in 1981 which is not correct. I tried a range of initial guesses but they all converge to the same number.
I am using solver to solve an optimisation problem I have. I need to apply a new solver to every populated row of my sheet. My solver code is as follows:
Sub solverloop()
SolverOk SetCell:="$Z$2", MaxMinVal:=3, ValueOf:="0", ByChange:="$N$2:$O$2"
SolverSolve
End Sub
The code above applies the solver to row 2. My sheet has roughly 500 populated rows. I need to write a macro to loop solver over each row, accept the solution provided by solver, then move to the next row. i would also like to close the loop automatically when the last populated row is reached.
I'm trying to run a macro which will allow me to run solver and keep the solution.. I have managed to get the macro to work. However, does anyone knows how I can ensure that solver's solution can be automatically saved without prompting the user whether to save the solution?

Eve Blue is the manager of Southland Furniture store and she is planning a New Years Day sale. The store has only 75 square feet of space available to display and stock this merchandise. During the sale each folding table costs $5, retails for $11 and takes up two square feet of space. Each chair costs $4, retails for $9 and takes up one square foot of space. You must order at least one chair and one table and, of course, they must be whole units. The maximum amount allocated for purchasing the tables and chairs for the sale is $280. Eve cannot sell more than 40 chairs but the demand for tables is unlimited. Eve asked you to help her determine how many tables and chairs she should purchase in order to make the most profit.

I have a problem with a macro in Excel 2007. It invokes
solver and creates an answer report. Please find the VB
code for macro, below.
When I run a group of macros for some reason after the marcro runs and I hit F2 excel crashes.
I have figured out that it is one of the marcros that makes the excel crash. It is only when I run the solver application. The code is below. Any thoughts why hitting F2 after running this marcro would crash the machine?
I would like the XL add-in 'Solver' to automatically find a value 'M' in the equation attached, based on 'R' being 30%.
I also would like to be able to manually enter 'M' based if I would like 'R' to be different from 30%.
How can I program this in VBA, and have the equation automatically done in the first instance simply by clicking on cell 'R'.
See my file. I want to calcuate a % needed (20%) to add to a another material. Should be easy but I can not figure it out.
