simplifying a constraint system?
by Basile STARYNKEVITCH 06 Apr '09

06 Apr '09

Hello All [Sorry for the very naive & basic question] I have constructed some constraint system using the C API. I know I'm done constructing it. Is there some function to "simplify" it or represent it more efficiently? - perhaps onverting it to NNC_Polyhedron and backwards, using ppl_new_NNC_Polyhedron_from_Constraint_System <http://www.cs.unipr.it/ppl/Documentation/user/ppl-user-c-interface-0.10-htm…> & ppl_Polyhedron_get_minimuzed_constraints <http://www.cs.unipr.it/ppl/Documentation/user/ppl-user-c-interface-0.10-htm…> ? Is there some function to test that it is empty? - perhaps using <http://www.cs.unipr.it/ppl/Documentation/user/ppl-user-c-interface-0.10-htm…>ppl_new_NNC_Polyhedron_from_Constraint_System <http://www.cs.unipr.it/ppl/Documentation/user/ppl-user-c-interface-0.10-htm…> & ppl_Polyhedron_affine_dimension <http://www.cs.unipr.it/ppl/Documentation/user/ppl-user-c-interface-0.10-htm…> A concrete case occuring to me is the constraint system of two variables n and y with constraints {n = 10, y = 17, -n >= 0} I need to compute that it is empty. Is there some function to test that it has integer elements, in the sense that there exist an integer setting of the variables such as the constraint are satisfied? - perhaps using grids? Sorry for such basic questions! Regards. PS I'm only using the C API! -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basile<at>starynkevitch<dot>net mobile: +33 6 8501 2359 8, rue de la Faiencerie, 92340 Bourg La Reine, France *** opinions {are only mines, sont seulement les miennes} ***
