Subject [jira] [Commented] (MATH-1032) Recover final tableau values from SimplexSolver
Date Wed, 04 Sep 2013 20:59:52 GMT

    [ https://issues.apache.org/jira/browse/MATH-1032?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13758331#comment-13758331

Renato Cherullo commented on MATH-1032:
---------------------------------------

I realize that I didn't provide much specifics, but I couldn't find any reference to this
kind of feature here or in the ML, so I just wanted to kick start the discussion.

Well, just adding a getter to the final tableau is clearly not enough. The SimplexTableau
needs some new getters too, for example to retrieve the column which corresponds to the slack
variable of a given constraint.

I'm willing to implement this, but I need some guidance.

> When the Simplex algorithm finds an optimal solution, the tableau is full of useful information
that (in the current implementation) can't be retrieved, like shadow prices, sensitivity info,
etc.
> Thus, it would be great if a future version allowed for the retrieval of such information.
