    Description

      When I express a Linear Programming problem in a Pure Java environment, I get a solution A.

      When I express thje same linear programming problem in a Java Android environment using the same problem modelling classes, I get a solution A', which doesn't match the constraints I express.

      For instance, If I have a set of Xi variables, with each Xi >= 0, I can get some Xj < 0.

      Or if I have Xi >= a, then in the solution, I can have Xi < a.

      I noticed that for freechart library, they have made a special library for android (Jfreecharrtt for pure javan Afreechart for Android).

      I have tried to compile the source with my android app, but the problem is the same.

      Is it necessary to have a library built up for android devices ?

      Is it possible to have commons-math for android ?

      In advance thanks.

      Regards.

      Sylvain.
