Arggggg... Well, this interface is being rewritte anyway. I had a lot of things to do during the previous week (job application) but I should find some time to take care of these nasty patches in the next days :-) http://trac.sagemath.org/sage_trac/ticket/12220 > I'm using gcc 4.6.1.

It is actually part of Sage's source code : http://hg.sagemath.org/sage-main/file/c239be1054e0/sage/numerical/backends And you will find at the bottom of this page the instructions to use CPLEX with Sage : http://www.sagemath.org/doc/thematic_tutorials/linear_programming.html Note that the latest version of CPLEX requires an additional symbolic link. The previous page has not been updated since this ticket is still waiting for review : http://trac.sagemath.org/sage_trac/ticket/11958 > In terms of parallel algorithms, I'm really not sure what would be > appropriate at this point.

O_o Well, I do not understand what you mean by "parallelize the objective functions", but if you try to implement something at some point I guess it will be the kind of stuff that gets me interested immediately :-) 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
