Raghu Rangarajan commented on MATH-819:
---------------------------------------
Hi Thomas,
OK. I will try few more test cases and open a new defect if I see more issues.
I will leave it to you if you want to keep this defect open until it gets
fixed. Thanks.

> SimplexSolver - InfeasibleSolution when feasible
> ------------------------------------------------
>
> Key: MATH-819
> URL: https://issues.apache.org/jira/browse/MATH-819
> Project: Commons Math
> Issue Type: Bug
> Affects Versions: 3.1
> Environment: Windows 7, JDK 1.7.0_03
> Reporter: Raghu Rangarajan
> Attachments: CommonsSolver2.java, lp-octave.txt, test.log, test.mod,
> test.out

> I am seeing an odd behavior with the latest code in the main trunk (Directory
> revision: 1358535). The solver throws "NoFeasibleSolutionException" for a
> problem which has a feasible solution. Just by commenting out the last
> constraint, we get a feasible solution. And for that solution, the constraint
> in question does not seem to be playing a role.
