'Solver' for Linear Programming

Hi,
I'm a university student doing accounting in UK and I need to answer some questions on Linear Programming which I am supposed to solve using Microsoft Excel. To do this, I need 'solver' tool which i can get free from the internet. However, I do not use Microsoft Excel, but Number09. So, where can i get the 'solver' thingy from? Does Numbers09 even have the tool? I really need the 'solver' tool so badly...
Thanks!!
-Izwan-

Welcome to the forum .
Alas, Numbers is not the tool to use : it doesn't contain a solver.
Maybe ( I really wrote maybe ) we will get one with the next version.

Java Libraries for Linear Programming/ Optimisation / OR Related Topics

Dear all,
I am working on some applications dealing with optimisation of constraints spaces/resource.
I will probably need to engage linear programming / optimisation techniques or algorithms to solve the problems. I wonder if anyone know of any Java libraries for purpose (trying to write my own optimisation/linear programming solving packages will require way too much effort and re-inventing the wheel).
Many thanks!

Hi,
I wonder if there are more complete and comprehensive packages. I hope to find some libraries that will provide the optimal solution and at the same time with report generation facilities (i.e. sensitivity reports).
Any ideas / advices?

Integer linear programming

I have a question about linear programming in Labview. Is it possible to solve linear programming problems supporting integer variables (branch and bound code)?. For example:
f(z)=10*A+20*B+30*C                -->min!
Constraints:
    1*A+2*B+3*C>=20
    B<=5
A,B,C must be integers
The "Geometrical Version of LP in 2D.vi" is a great example to show how the "Linear Programming Simplex Method" works to solve this kind of problems. However, it does not support integer variables... How can I solve the problem above in Labview? Could I solve it using ActiveX controls to communicate with Excel solver?
Please help!! Thanks in advance
Traduce

Hi Ima,
     I have found some examples that show how to make ActiveX calls in LabVIEW in order to work with MSExcel:
Controlling Microsoft Excel for Office 2000 with an ActiveX Automation Server
Write Data to the Active Cell in Excel Using ActiveX
Reading Data from Excel
Controlling Microsoft Excel for Office 97 through ActiveX Automation
     You can find lots of examples on ni.com/devzone if you search for "excel activex". Hope it helps!

Payment method(s) are not allowed for this program / Program RFFOAVIS_FPAYM

Dear Friends,
In Se38 abap editor, I entered the program RFFOM100, i entered the details program run date,identification future,paying company code,payment methods T, House bank, Account Id and executed the program. I am getting the error 'Payment method(s) are not allowed for this program'.
Payment method S is not used in F110, It was not mentioned in vendor master or vendor invoice.It is not mentioned in fbzp in bank determination. When i tried to delete payment method 'S' the system shows a message Payment Method S is being used in the company code.
In the program RFFOAVIS_FPAYM, i entered the details program run date,identification future,paying company code,payment methods T, House bank, Account Id and executed the program. I am getting the error 'Program RFFOAVIS_FPAYM: No records selected'. But there open items or invoices.
Please suggest how to resolve the errors.
Regards
Sridhar

Hello,
Why are you directly executing these programs?
You will not expect these program to execute directly by going to SE38.
I would have configured the relevant payment methods in the country with DME structure or classical RFFO* programs, which in turn pick up the inherent programs at the time of running F110.
For example, if you need to generate BACS file for country GB, either you copy the GB_BACS to ZGB_BACS or use GB_BACS directly in FBZP settings.
Make sure that you have maintained OBPM1 / OBPM2 / OBPM3 and OBPM4 settings properly.
The system automatically gives the access to system RFFOAVIS_FPAYM. Prepare a variant against this program in F110. Relevant file gets generated to folder path mentioned in OBPM4 will get generated. The file get generated can be seen in AL11.
Hope this is informative and solves your issue.

Looking for a program that can handel import and export of palm doc files

I am looking for a program that can handel the import and export of palm doc Files that can convert them to to either txt or RTF files for Vista 32, running Palm Desktop 7.1.
Could anyone give me a few suggestions of any plug-ins that would be good me?
Hearns
Post relates to: Palm IIIxe
This question was solved.
View Solution.

Ok, you need to clean uninstall Palm desktop 6.2. Install Palm desktop 4.1.4 and download and install documents to go version 6.
Here are the clean uninstall instructioins for Vista.
You should first make a copy of your data to have just in case something
happens. You can find your data files by going to Start --> Documents -->
Palm OS Desktop. Highlight your Palm Desktop username and right click and
copy. Then go to your PC desktop right click on a blank spot and select paste.
If this is the first time you are installing Palm desktop and encountering a problem, skip the previous step.
Now you want to uninstall Palm Desktop and remove everything that has to do
with Palm Desktop from your computer.
Go to the following locations on the PC and delete the folders listed below.
C:\Program Files\Palm or Palm One
C:\Users\[Vista Login Name]\appdata\local\virtualstore\Program Files\Palm or
PalmOne
C:\Users\[Vista Login Name]\appdata
*Note you may need to view hidden folders to get to appdata. To do that go
into your control panel and open folder options. Go to view tab and uncheck
hide hidden files.
Once this is done you will need to delete some registry keys from your PC Operating System.
Word of warning, going here and deleting the wrong thing can cause your PC
from starting up, crashing and deletion of programs and data. If you feel
you are unsure of yourself, see if you have a friend that can help you or a
PC technician that you can pay to help you. This procedure will show them everything they need to delete. To make sure we have a good copy of the current registry, we need to do a backup of the Registry.
Go to start on the PC, in the search field type "regedit.exe" without quotes.
Highlight COMPUTER, go to File --> Export. Should pop up with a Save As box.
Current location is fine, should be in My Documents or save to a location you will remember. In the file name on the bottom type "backup[todaysdate]" i.e. backup07072008. Next, the hard part.
The easiest way to make sure your working with the correct key, highlight the key i.e. palm quick install, and press delete on your keyboard. It will ask you, are you sure. Say yes. Do the same thing for all keys below.
If you make a mistake, stop what you are doing. And call a PC technician.
BUT do not turn off your computer.
The reg keys are as follows (Note: some of theses reg keys will not be here
but if they are delete them)
* HKEY_CURRENT_USER\Software\U.S. Robotics\Palm Quick Install
* HKEY_CURRENT_USER\Software\U.S. Robotics\PalmOne File Transfer
* HKEY_CURRENT_USER\Software\U.S. Robotics\Pilot Desktop
* HKEY_CURRENT_USER\Software\Palm
* HKEY_CURRENT_USER\Software\Palm, Inc.
* HKEY_CURRENT_USER\Software\PalmDesktopAutorun
* HKEY_CURRENT_USER\Software\palmOne
* HKEY_CURRENT_USER\Software\PalmSource
* HKEY_LOCAL_MACHINE\Software\PalmSource or anything else that says palm
Next reboot your computer.
Then reinstall your palm desktop from the CD and do a hotsync. Use the username that is on the handheld.

ABAP and Linear Programming

Hello,
We are developing an application to arrive at an optimal amount of component inventory to carry for a production line in a manufacturing environment. Part of this application requires the execution of a linear programming technique called "Revised (Primal) Simplex Method".
Has anyone ever done linear programming in ABAP ?
Has anyone ever written an ABAP program that calls a routine written in another language that used linear programming ?
Any help would be appreciated.

Hi Sefy,
We were unable to find a way to resolve our issue with ABAP, so we have also looked at external packages. We found a software package called C-Plex by a company named I-Log that seems to suit our needs. We are have not started using it yet.
As John mentions in a future post, APO has a lot of optimization tools but we are not aware of any that can be used in the manner we need.
Good luck with your implementation.

Help need on System setup for java programming

HELP BADLY NEEDED!
I recently installed java (jdk version8 152mb) on my HP630 win7 because i want to learn java. But when practising, after using notepad to code samples like "Hello Word" and saving it with .java format, it still cannot run on my pc.
Pls i think i need a complete and comprehensible guide on how to install and prepare my win7 laptop for java programming.
Thanks in anticipation

Hello,
one suggestion is to ensure your system's environment PATH has the Java installation path included, so that it knows where to look to run Java.
(See attached pix).
1st) Find out where Java was installed to on your system: For example, on my Win7 PC, Java was installed to 'C:\Program Files (x86)\Java' directory.
However, my path to the actual binaries is 'C:\Program Files (x86)\Java\jre7\bin'; this is the value I added to my system PATH.
2nd) Check what your System's PATH has: You can do this by looking at the Environment Variables under System Properties:
1) Search for Control Panel, then go to System & Security, then to System, then to 'Advanced System settings'.
2) Click on 'Environment Variables...'
3) Under the 'System variables' pane, use the scroll bar to find 'Path', and click on 'Edit...'.
4) Here is where you add your Java path (as noted above): Note that I appended my java path to the existing Path text, taking care to separate the previous path with a semi-colon (';').
For example, this was my existing 'Path': "C:\Program Files\CollabNet\"...and now it looks like this 'C:\Program Files\CollabNet\;C:\Program Files (x86)\Java\jre7\bin'.
5) Click OK, OK, OK out of all those dialogs.
Now..restart your JVM or attempt to run your Java program!.
Good luck.

Tcode for standard program REL_DELNOTE

Cud you please tell me what is the T Code for Standard program 'Rel_Delnote'. The smartform name is Z_LOADING_AUTHORIZATION

Hi Awanish,
The program RLE_DELNOTE is not used in any TCode(s). You should manually create a 'Z' TCode using SE93 for this RLE_DELNOTE.
If at all you want your Smartform Z_LOADING_AUTHORIZATION to get triggered then execute the NACE TCode and configure your Smartform to the required Output type (for Eg: LD00 - Delivery Note) of corresponding Application (V2 - Shipping).
Hope this solves your problem. Reward accordingly.

Tutorials for dailog programming & screen painter

HI,
I am new to the topics above and i want to have information about it . plzz proivde me d simple and easiest tutorials for it.

Hi,
A dialog program consists of the following basic components:
Screens (dynpros)
Each dialog in an SAP system is controlled by dynpros. A dynpro (DYnamic PROgram) consists of a screen and its flow logic and controls exactly one dialog step. The flow logic determines which processing takes place before displaying the screen (PBO-Process Before Output) and after receiving the entries the user made on the screen (PAI-Process After Input).
The screen layout fixed in the Screen Painter determines the positions of input/output fields, text fields, and graphical elements such as radio buttons and checkboxes. In addition, the Menu Painter allows to store menus, icons, pushbuttons, and function keys in one or more GUI statuses. Dynpros and GUI statuses refer to the ABAP/4 program that control the sequence of the dynpros and GUI statuses at runtime.
ABAP/4 module pool
Each dynpro refers to exactly one ABAP/4 dialog program. Such a dialog program is also called a module pool, since it consists of interactive modules. The flow logic of a dynpro contains calls of modules from the corresponding module pool. Interactive modules called at the PBO event are used to prepare the screen template in accordance to the context, for example by setting field contents or by suppressing fields from the display that are not needed. Interactive modules called at the PAI event are used to check the user input and to trigger appropriate dialog steps, such as the update task.
All dynpros to be called from within one transaction refer to a common module pool. The dynpros of a module pool are numbered. By default, the system stores for each dynpro the dynpro to be displayed next. This dynpro sequence or chain can be linear as well as cyclic. From within a dynpro chain, you can even call another dynpro chain and, after processing it, return to the original chain.

Installation problems solved for XP SP2 systems.

I've been pulling my hair for days trying to install SC2, but had no luck.
The installation process DOES have a bug. Use the following tactic in addition to disabling any firewalls and virus programs:
Right-click on the installer file and select 'Compatibility' . Click 'Run this program in compatibility mode:'. Finally, simply select Windows NT 4.0 (Service Pack 5) mode.
Problem solved for now. Hope this helps.

This is very interesting akian ty - I will definitely try this at the weekend. I can install and run on a laptop with XP SP2 - and it had previous versions installed on it. However on the desktop PC I have not been able to install.
My problems have been with opening ports and appserver not starting. I will post back here how I get on with your tip. Thanks and also for the other suggestions that people have tried to help me with.

Sound works for all programs in Windows 7 (64-bit) except iTunes (64-bit) which stopped working after months of working fine.

Sound works fine for all programs on Windows 7 (64-bit) except recently 64-bit iTunes just stopped working. I believe the sound stopped right after downloading the 10.5.1.42 version of iTunes.

Sir,
I had the same problem with itunes 10.5 with creative labs sound card. The only way I could solve it was to use the built in sound on my video card. But needless to say I have a very high end video card, I have the NVIDIA GTX 580. And after I used the sound on my video card everything worked great.

Looking for Quadractic programming package

Anyone know where I could get hold of a java package for quadratic programming?

Actually this is a line of attack I'm considering on a problem I posed a couple of weeks back, and for which I got no response.
The project involved is a geographical information system. One of it's functions is to compose composite maps which may have map data superimposed from several sources, and also may have scales, captions, legends etc..
This composition is specified by an XML file, which works like java.swing.Box in the way it organizes space.
The specific problem arrises when sizes for the various frames are not explicitly provided. Some frames have minimum feasible dimensions, some have fixed aspect ratios, some are greedy for teritory in one or both dimensions, some aren't improved by being enlarged.
I've just written code which does this allocation of teritory by linear programming. The trouble is the qualities I'm trying to optimise are still rather vague, and don't want to be linear. For example frames that display actual maps want to be as large as possible and still fit, but if there is more than one of them then they should, by default, be of similar area. If I take linear objecitve functions (e.g. the sum of the two dimensions) then one very large one and one vanishingly small one gives me the same objective score as two of equal size.
I'm considering modifying the simplex algorithm, having find an optimum vertex, to look for neigbouring verticies with the same score and then average them, in effect if there's an edge, facet, hyperfacet or whatever of the simplex tangental to the objective planes then take the middle of it.
I'll probably experiment with that today.
If I can find a quadratic programming package I should be able to experiment without a big investment of time.
