Separate public-facing and internal-facing interfaces to Statistics.

12 years agoGeneral subscriber infrastructure for NodeManager, as discussed in the
Morgan Deters [Wed, 19 Sep 2012 21:21:00 +0000 (21:21 +0000)]
General subscriber infrastructure for NodeManager, as discussed in the
meeting last week.  The SmtEngine now subscribes to NodeManager events,
does appropriate dumping of variable declarations, and notifies the Model
class.

The way to create a skolem is now:

  nodeManager->mkSkolem("myvar_$$", TypeNode, "is a variable created by the theory of Foo")

The first argument is the name of the skolem, and the (optional) "$$" is a
placeholder for the node id (to get a unique name).  Without a "$$", a "_$$"
is automatically appended to the given name.

The second argument is the type.

The (optional, but recommended) third argument is a comment, used by the
dump infrastructure to indicate what the variable is for / who owns it.

An optional fourth argument (not shown) allows you to specify flags that
control the behavior (e.g., don't do notification, and/or don't make a
unique name).  Look at the documentation for details on these.

In particular, the above means you can't just do a mkSkolem(boolType) for
example---you have to specify a name and (hopefully also,
but it's optional) a comment.  This leads to easier debugging than the
anonymous skolems before, since we'll be able to track where the skolems
came from.

Much of the Model and Dump stuff, as well as some Command stuff, is cleaned up
by this commit.  Some remains to be cleaned up.

Morgan Deters [Wed, 12 Sep 2012 20:31:59 +0000 (20:31 +0000)]
Adding model assertions after SAT responses.

To enable, use --check-models.  Turning on the option can be done in debug or optimized builds, regardless of whether normal assertions are on or not.  This is to allow us to check the generated models in long-running queries, and might be useful to end users as a double-check too.

By default, --check-models is quiet (no output unless it detects a problem).  That allows regression runs to pass unless there are problems:

  make regress CVC4_REGRESSION_ARGS=--check-models

To see it work, use -v in addition to --check-models.

There may still be bugs in the feature itself, but already I've found some apparent model-generation bugs (and discussed with Andy) from this feature, so it seems useful in its current state.

--check-models turns on what SMT-LIBv2 calls "interactive mode" (which keeps the list of user assertions around), and also implies --produce-models.  This version does NOT require incremental-mode, which one design did (the one mentioned in yesterday's meeting).

Also:

* TheoryUF::collectModelInfo() now generates UninterpretedConstants (rather than non-constants)
* The UF rewriter now reduces (APPLY_UF (LAMBDA...) args...), and treats uninterpreted constants correctly (e.g. uc_U_1 != uc_U_2)
* The SubstitutionMap now supports substitutions of operators for paramaterized kinds (e.g., function symbols)
