Subject [jira] Updated: (MATH-246) Simplex Method Implementation
Date Wed, 08 Apr 2009 21:28:12 GMT

     [ https://issues.apache.org/jira/browse/MATH-246?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Benjamin McCann updated MATH-246:
---------------------------------

    Attachment: test.patch
                simplex.patch

I ran into a case today where the SimplexSolver was failing because I wasn't allowing for
error when doing comparisons.  This patch uses MathUtils to do all comparisons.
