Welcome to this very small and simple LP-optimizer! Now, you have the option to solve very small LP problems directly over the INTERNET without any special software. Just place the coefficients in the right places below and press SOLVE. Then, you get the optimal results.

Example:
With the software LINDO from www.LINDO.com we can solve this optimization problem:
-----------------------------------------------------------
Optimization problem:

max 10X + 20 Y
s.t.
1x + 1y =< 10
2x + 2y =< 30

Optimization result:

        OBJECTIVE FUNCTION VALUE

        1)      200.0000

  VARIABLE        VALUE          REDUCED COST
         X                  0.000000         10.000000
         Y                 10.000000          0.000000
 

       ROW   SLACK OR SURPLUS     DUAL PRICES
        2)                      0.000000                20.000000
        3)                      10.000000              0.000000

-----------------------------------------------------------

In order to get the same result with this Java program, you just write the following "Table 1"(*) version of the optimization problem:
 

-10

-20

0

0

0

1

1

1

0

10

2

2

0

1

30

Then you press the SOLVE button and the optimal results should appear below "Table 1".
