[PPL-devel] Question about ALV & PPL

[Tevfik Bultan]

This was an extension to Action Language Verifier (ALV) that was done as a 
class project. We did not integrate it to the later versions of ALV. The 
current version of ALV that is available at:
http://www.cs.ucsb.edu/~bultan/composite/
uses two different representations for integer variables: 1) polyhedra 
representation as implemented in Omega library and 2) automata 
representation built on top off the MONA automata package. Both 
representations can handle the full Presburger arithmetic.

I think it should be possible to modify Ken's interface to the newer 
version of the ALV.

Best,
