Morgan Deters [Tue, 28 May 2013 17:29:59 +0000 (13:29 -0400)]
Standardize SMT-LIBv2 set of logics to use LogicInfo.

Previously, SMT-LIB logics were treated specially, as in SMT-LIB v1.2.
This led to inconsistencies---such as nonstandard logics like "QF_LIRA"
being accepted in set-logic but not providing the "Real" sort.  Now,
the LogicInfo is used and queried, so nonstandard logics should work
fine and declare the correct symbols.  SMT-LIB v1.2, unfortunately,
can't take advantage of this fully since symbols like "Array" have
substantially different meanings in different logics.

Don't allow get-model & co after a user push/pop

This makes us more strictly adhere to the spec, but it's useful anyway:
previously we would support a get-model until the problem was explicitly
changed with e.g. a new assertion.  That meant you could check-sat, then
pop, then get-model, but you'd only get the part of the model still in

None of these are enabled by default, so any performance impact
counts as a bug

Options added are:

--decision-threshold=N :default 0
+ ignore all nodes greater than threshold in first attempt to pick decision

--decision-use-weight bool :default false
+ use the weight nodes (locally, by looking at children) to direct recursive search

--decision-random-weight=N int :default 0
+ assign random weights to nodes between 0 and N-1 (0: disable)

--decision-weight-internal=HOW
+ computer weights of internal nodes using children: off, max, sum, usr1 (meaning evolving)

      type trivalued, to be able to distinguish between
      "partial exploration" vs "done exploration but found nothing"

    * keep additional data structure to remember to what extent the
      partial exploration has been completed so not to repeat it. we
      can use this to make multiple passes on formula with arbritrary
