Well, that's a problem I would be very glad to be able to answer myself.... But it highly depends on the characteristics of your equations... CPLEX can solve some instances (it is proprietary, though) depending on the matrix of constraints, but for general inequalities I have the same problem you have :-/ Nathann -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org
