Subject [jira] [Created] (MATH-794) LP on android devices
Date Wed, 30 May 2012 08:51:22 GMT
Sylvain Roussé created MATH-794:

             Summary: LP on android devices
                 Key: MATH-794
             Project: Commons Math
          Issue Type: Bug
    Affects Versions: 3.0
         Environment: Android 2.2 JDK 1.6
            Reporter: Sylvain Roussé

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

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

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.
