CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2002-10-07 11:31:22

Modified files: src : Polyhedron.cc

Log message: Modified method Polyhedron::is_BBRZ02_stabilizing(x, y) so that: - we check for a decreasing number of rays lying inside the faces of an orthant. - we check whether x and y do happens to be the same polyhedron. Modified method Polyhedron::BBRZ02_widening_assign(y) to apply, as a last resort, the widening H79.
