[jira] [Created] (MATH-1080) The LinearConstraintSet shall return its constraints in a deterministic way

Thomas Neidhart created MATH-1080:
-------------------------------------

             Summary: The LinearConstraintSet shall return its constraints in a deterministic way
                 Key: MATH-1080
                 URL: https://issues.apache.org/jira/browse/MATH-1080
             Project: Commons Math
          Issue Type: Bug
            Reporter: Thomas Neidhart
            Priority: Minor


As previously discussed on the mailinglist, the LinearConstraintSet should return its internally stored LinearConstraints in the same iteration order as they have been provided via its constructor.

This ensures that the execution of the same linear problem results in the same results each time it is executed. This is especially important when linear problems are loaded from a file, e.g. mps format, and makes it simpler to debug problems and compare with other solvers which do the same thing.
