i quess that it uses the simplex method.

thanks, unfortunatly that was not what i was looking for.
i am looking for an equivalent of the Solver in Excel, not the Goal Seek.
The solver i am looking for (if it exists) should be able to calculate 
optimization problems, such as LP-problems. that means it must be able to handle 
 more then one variable.


Perhaps you misunderstood the FAQ item. Goal Seek is what you want in
OOo. To learn more about it use Help while in Calc and select Help >
Contents > Index > Search term > goal seek.
out of curiosity, could you give me an example of how to solve the following 
using Goal Seek?

max  5*x1 + 2*x2
s.t.
x1      <= 100
     x2 <= 200
x1 + x2 <= 150

the optimal solution should occur when x1=100, x2=50 and the value of max 5*x1 + 
2*x2 = 600.
