I suspect you want to use the compiler type checking functionality to check for errors, but I don't think it is acceptable to transform a perfectly working mathematical notation: <pre> x + 2y <= 6 </pre> to <pre> new double[] { 1, 2 }, Relationship.LEQ, 6 </pre> just to use the compiler to check for errors. Also, why this double[] casting? Is the L.P. able to work in the integer domain? Addittionally using a getter named getPoint <pre> solution.getPoint()[0] </pre> to return an array of points does not seem to make a lot of sense to me. My Java knowledge is minimal, and I suspect the language does not encourage to leave the <i>set values, compute, get results</i> way of thinking but the API is horrible. The original text description is written in 53 characters and is easier to understand than the 478 lines used in the Java code.

I suspect you want to use the compiler type checking functionality to check for errors, but I don’t think it is acceptable to transform a perfectly working mathematical notation:

 x + 2y < = 6

to 

new double[] { 1, 2 }, Relationship.LEQ, 6

just to use the compiler to check for errors.

Also, why this double[] casting? Is the L.P. able to work in the integer domain?

Addittionally using a getter named getPoint

solution.getPoint()[0]

to return an array of points does not seem to make a lot of sense to me.

Also, if you want a different interface to the solver you can run it via Google Spreadsheets.
