assign names to variables.
by Zell 07 Aug '12

07 Aug '12

Dear all, Is there a quick way to pretty-print a Box or Polyhedha object using my variables names rather than the build-in "A", "B", "C"...? For example, below are an interval analysis result for a single instruction "x=10". PPL uses its built-in names A,B,...for each dimension. ******************************* {true} x = 10 {A in 10} ******************************* I do not see how to assign a user-defined names for PPL's variable objects. Any ideas? Thanks. Zell.

Write constraints in JAVA interface as in C++ ?
by Zell 01 Aug '12

01 Aug '12

Hello, If I understand correctly, there is no support in JAVA interface to add constraints as easy as in C++, for example, in C++, cs.insert(B >= 0); cs.insert(A >= 0); cs.insert(B == 5); cs.insert(B <= 7); Otherwise, I do not see the domain Box in JAVA interface. What would be the instruction to enable it? (I am under Mac OS x, for information) Thanks. Zell.

Hello, I am using PPL's Java interface for static program analysis. The library is known to be "very user friendly". However, I cannot find a working example (say, a hello world) for PPL. No examples are provided in the user's manual. Could you show me some examples? Thanks. Zell.
