How to use optaplanner to solve a nonlinear constrained multivariable equation - Java

Question

I want to solve a nonlinear multivariable equation with discrete values like this one:

x*y + z + t - 10 = 0

with constraints:

10 < x < 100

etc..

I did some research and I believe optaplanner is the way to go. I downloaded the package from their website, but I am a little lost.

Can someone tell me how to write the code for this problem using optaplanner's libray?

What are `x`, `y`, `z` and `t`? OptaPlanner supports types, OO and polymorphism, so why regress to a non-OO model? — Geoffrey De Smet, Jan 11 '16 at 08:05

You can use the JAMA to solve this. I'd recommend a good LU decomposition method. Also there are more sophisticated libraries like: FPL and Benoit

There's no guarantee, of course, that there is a solution.

I think Jama is only for linear equations. Is that true? – dirac Jan 11 '16 at 06:40
Yes, that's true, I updated the answer. – m.aibin Jan 11 '16 at 06:46
