Simplex Tableau Method Program
A Homework Help Tool for Finite Math, Linear Programming, & Business Math
This is faily easy to Use this simplex method utility; it's extremely user-friendly. Just press the "example" button to show an example of setting up a linear programming problem. Then leave it as is, modify it, or enter a new problem, and press "Solve." This is a great homework help utility for solving simplex tableu problems in finite math and business math classes.
Notes:
- Do not use commas in large numbers. For example, enter 54,321 as 54321.
- The utility is rather flexible with input. For instance, the following format will also be accepted (inequalities seperated by commas):
MAXIMIZE P = x + y subject to x + y <= 6, 3x + y >= 8
Of course "P" means profit, and we ALWAYS want to maximize profit!!! ;-)
NOTE: You can also use a "MINIMIZE" command option, for example to minimize cost.
Note that "<=" means "less than or equal to" and ">=" means "greater than or equal to".
- Decimal mode displays all the tableaus (and results) as decimals, rounded to the number of significant digits you select (up to 13, depending on your processor and browser).
- Fraction mode converts all decimals to fractions and displays all the tableaus (and solutions) as fractions.
- Integer Mode eliminates decimals and fractions in all the tableaus and displays the solution as fractions.
- Mac users: you can use the inequality symbols "option+<" and "option+>" instead of "<=" and ">=" if you like, but some browsers may have trouble with this.
- Solution Display Some browsers (including some versions of Internet Explorer) use a sans serif proportional width font in text boxes. This will cause the display of solutions to be "dis-aligned" and appear a little messy. You can remedy this by changing the "Sans Serif" font in your browser preferences to "Courier" or some other fixed-width font, and then reloading the page.
