I'm working on a solution of linear programming problem using Simplex method.
I need the best programming language to design it and how to go about it if possible. Please help.

Try using VB 6.0 or .Net

Hey blissbay, thats interesting to me. Linear programming is one of the courses i took last semester. The best programming language u can use to do this depends on which u can use. Moreover, any programming language can be used for it. C++, Java, Vbasic and so on. So choose the one u can use. I'll start thinking of doing something on it myself. Luck.

if u're in Lagos, i suggest u take a trip down 2 Yabatech; go to their computer dept. & see if u can get someone to help u.
Operations Research is a course everybody in the HND level there have to do & they do give 'em some pretty serious assignments & term papers. i'm pretty sure you'll find someone there that'll help you.

You can Use any programming language u are familiar with, it all depends on your algorithm

Excel VBA is very cheap, simple, powerful and good. trust me you can't go wrong

is that an application to solve linear programming problems or a programming language?

pally you can use even QBasic, C++ or FORTRAN if you wish. The most important thing is to write out a very good algorithm of solving LP problems.

Linear Programming problem using simplex method was one of my turning points in programming.
It's not about the language you use, but the strength and logic of your algorithm
You may spend 2days thinking the algorithm, and simply write the code in 2hrs !, as simple as that, if you have laid the bed well (I mean thought out a good algorithm).
After i did this problem back then in H.N.D I, i decided i was going to be a programmer.
If you are the brave-hearted type, PLS do it on your own, if you contract out the work, you'll keep running to solutions for the rest of your programming life.
He who fights and runs away wil leave to fight another day.
I used Qbasic back then, but no matter the language you use, vow never to write spaghetti code.
ORGANISE your code the OOP way, and you'll enjoy doing the work, plus, it will make the work a lot of fun.
But watch out, this is about the simplest assignment in operations research, wait till you write a program to solve assignment problem, then you will know what's up.
Wishing u luck.

I did alot of linear programming (in numerical analysis ) while at school. the first step is writing a good algorithm; further engineering mathematics can be of help. then, you can use any programmiong language to do the job. I did my using C++. java and VB can also do the trick.

enjoy may guy!

If you want to just solve a linear programming assignment, the programs like LINDO, Management Scientist should do whatever you want it to do for you, but if you want to write a program for solving linear programming, I think some who are more knowledgeable that myself have already given the hints.

Enjoy your time

Please, how can i get the LINDO, Management Scientist software? Do you have any link to a website i can, maybe download it.

u can use advanced engineering maths by KA STROUD

In Numerical Analysis?? Are u sure you know what the guy is talking about?? He's talking about Linear programming in Operations Research o! Which school is dat sef?

where are u? i'm still waiting for u to respond.

Ishmeal, I did the same thing when I was in the school. I was the first programmer that was able to design it and get it distributed but I did it Q-basic. If u need it I will give but if you want me to do it in any other language you may have to pay for my biz time.

Q-basic own if free with code.
I even went ahead to arrange it in Maximation , minimization and mixed contraint, so u choose the one u need from the program and it does it for you.

luckyCo tried to contact u but ur email is hidden. pls can u send ur full contact.my email is:swblast2007@yahoo.com and no. is 07035106199 thanks

Contacted

Congrats!! but i no argue with you now; na the guy wey say him sabi am say him do am for Numerical Analysis i bin dey ask question. Did you do it in Ops Research or Numerical Analysis??

I did mine is operations research.

luckyCO:

I did mine is operations research.

i did LP in Operations Research too. i was wondering the school the other guy attended where Linear programming is taught as a topic in Numerical Analysis, because in Nigeria LP is a topic in Ops Research or QA/QT.

luckyCO could you send me the code, for the simplex method, and how much do you need for doing it in Java?

WinQSB is the best for Linear Programming. You don't have to write the code from scratch. It already provides you with everything including shadow prices etc. For the Simplex method, I strongly recommend WinQSB.

Otherwise, just do your regular VBA or C++ thing.

without doubt use MATLAB. It is for purposes such as this that it was made. It contain mathematical functions precoded in its library.it save u work energy and time. if uar not comfortable with it use VB6.0. Pls let me know if u've completed the stuff

I want ter bring this thread back!!!

Does anyone actually possess code of an implementation of the algo, or even maybe the algo itself?

This was my final year project.i used java program.i still have the soft copy and is working fine, all u need to do is edit and copy and paste.holla me on 08033594339.

I'm fairly sure I have worked this out correctly but before I commit it to certain knowledge, I want someone to cite that I got the answer right to solve this linear equation

2x/3 - 4x/5 = 7/9

I got X= 5 5/6

Sorry if this is a bit trivial but I just couldn't find another way to find the answer to the equation I was set at uni.

Thank you

hey pls if someone can send me the code for dual simplex method in C/C++ that would be great

I beg tell am say plenty people dey here wey study math wella
