[jira] [Created] (MATH-1082) Existing cutOff mechanism in SimplexSolver can lead to wrong solutions

Thomas Neidhart created MATH-1082:
-------------------------------------

             Summary: Existing cutOff mechanism in SimplexSolver can lead to wrong solutions
                 Key: MATH-1082
                 URL: https://issues.apache.org/jira/browse/MATH-1082
             Project: Commons Math
          Issue Type: Bug
            Reporter: Thomas Neidhart
             Fix For: 3.2


The cutOff mechanism introduced in MATH-828 does not work in call cases correctly.

Tests with the example from netlib have shown that sometimes an invalid solution is returned because of this.
