Module: ppl/ppl Branch: master Commit: ea6946e6d9a5db09dcfce63049b965b7052ce1d8 URL: http://www.cs.unipr.it/git/gitweb.cgi?p=ppl/ppl.git;a=commit;h=ea6946e6d9a5d...

Author: Enea Zaffanella zaffanella@cs.unipr.it Date: Mon Oct 17 09:48:26 2011 +0200

Added test showing a bug when solving again a 0-dimensional MIP_Problem. The bug only manifests when a previously solved 0-dimensional MIP_Problem is solved again after having modified it (that is, after changing optimization mode or optimization function).
