Issue created by migration from Trac.

Original creator: sr

Original creation time: 2008-06-09 15:07:50

Assignee: menal

Version:

I use OsiSymSolverInterface to solve an LP, then I add many additional columns in a reformulation of the problem. This works, but I have noticed that, when adding a large number of additional columns, it is quite slow. (The addCols method seems to call addCol in a loop.)

Is there an alternative method for adding a large number of columns which would run faster?

And, thanks-- symphony is a great product and much appreciated.
