some questions regarding PPL
by Bishoksan Kafle 12 Feb '16

12 Feb '16

Hi PPL-developers I would be glad if you could help me find answers to the following questions: 1. Having software verification in mind (problems over integers) which abstract domain(s) (more precisely domains provided by PPL) provide good trade-off between complexity and expressiveness? 2. In the article (http://bugseng.com/products/ppl/documentation/BagnaraRZH02.pdf), you mentioned that poly_hull_assign is different from upper_bound_assign for Polyhedra, but in the user manual I found the following text: [cid:BC9F6334-FB66-4E2B-BE47-2E4A8D844CD6] What are the differences between these two functions? Do they differ in precision? complexity? 3. What is the function corresponding to poly_hull_assign for Octagon? Many thanks in advance Bishoksan

Parma Polyhedra Library 1.2
by Roberto Bagnara 11 Feb '16

11 Feb '16

The core development team is very pleased to announce the availability of the long-awaited release 1.2 of the Parma Polyhedra Library. This release includes a major efficiency improvement to the conversion procedure for polyhedra, a few bugfixes and numerous portability improvements. The precise list of user-visible changes is below. For more information, please come and visit the PPL web site at http://bugseng.com/products/ppl On behalf of all the past and present developers listed at http://bugseng.com/products/ppl/credits and in the file CREDITS, Roberto Bagnara Patricia M. Hill Enea Zaffanella Abramo Bagnara -------------------------------------------------------------------------- NEWS for version 1.2 (released on February 11, 2016) -------------------------------------------------------------------------- New and Changed Features ======================== o Improved the efficiency of the conversion procedure for polyhedra by adding a quick adjacency check. o In the Java language interface, throw an exception when trying to build a disequality Constraint. Bugfixes ======== o Fixed a bug in the implementation of methods Pointset_Powerset<PSET>::relation_with(const Constraint&) const; and Pointset_Powerset<PSET>::relation_with(const Congruence&) const; whereby the computed result for relations strictly_intersects() and saturates() could have been wrong. o Fixed a bug in the implementation of dense rows. o Portability improved. -- Prof. Roberto Bagnara Applied Formal Methods Laboratory - University of Parma, Italy mailto:bagnara@cs.unipr.it BUGSENG srl - http://bugseng.com mailto:roberto.bagnara@bugseng.com
