CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2002-10-05 22:16:25

Modified files: src : Polyhedron.defs.hh Polyhedron.cc

Log message: Added new private method void Polyhedron::select_H79_constraints(const Polyhedron& y, ConSys& cs_selection) const; that selects the common constraints of *this and y (into cs_selection) according to H79. Used the method both in H79_widening and in BBRZ02_widening. Modified the second technique of BBRZ02 to have more chances that it will produce a stabilizing sequence of polyhedra. Added a few outputs for the debugging of BBRZ02_widening.
