CVSROOT: /cvs/ppl Module name: ppl Changes by: zaffanella@cs.unipr.it 2002-04-16 09:53:33

Modified files: src : Polyhedron.cc

Log message: Test NNCminimize6 has shown that our check for topological closure was relying on a false invariant (namely, that in a weakly minimized constraint system any strict inequality can be made redundant by another strict inequality only). Corrected the implementation of is_topologically_closed().
