Subject [jira] Commented: (MATH-246) Simplex Method Implementation
Date Tue, 02 Feb 2010 21:32:18 GMT

    [ https://issues.apache.org/jira/browse/MATH-246?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12828771#action_12828771
] 

Benjamin McCann commented on MATH-246:
--------------------------------------

The epsilon is used to decide equality between floating point numbers.  If they are within
the epsilon then they are considered equal.  It does help avoid cycling.  I'm not sure how
to decide what an optimal value is.
