Bernhard Gleiss 4148ee128c fixed bug, which added too many edges between super-source and source in the case where the source was used by multiple inferences 2018-06-14 16:08:47 -07:00

Arie Gurfinkel 890bc0f7c9 fix scoped_weakness 
forgot to save current state of params before resetting them

Arie Gurfinkel 68518b0e32 propagate weakness from pob down to all related checks 
If a pob was discharged with a weak solver, propagate the level of
weakness to inductive generalization and to lemma propagation.

Arie Gurfinkel b8b3703511 improved implementation of is_qblocked() 
Disabled by default. Has no effect if ran with the default set of
options where qlemmas=true  and instantiate=true
 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 371ba4fbc0 added parameters that seem to work well with quantifiers and arith 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 27d8fa4a34 hard-code quantifier weight to 15 
With default settings, the eager threshold is 10 and lazy is 20.  15
puts us in the middle ensuring that lemmas are instantiated when UNSAT
and otherwise delayed.
 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 135a4a765f Adding grounding of the current lemma 
In addition to adding the necessary instance of a quantified lemma,
add its grounding over the global set of skolems.

Arie Gurfinkel 6cf68bee80 app ordering that puts special skolem constants first 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 9f0eb367b1 ground lemmas during propagation when qlemmas are disabled 
When asserting quantified lemmas are disabled, ground a lemma
explicitly during propagate to make sure that it is ground using our
local set of skolem constants.
 2018-06-14 16:08:47 -07:00
Arie Gurfinkel 5da0753269 (spacer) add instances even when a q-lemma already exists 
It is possible that a new instance of a quantified lemma is discovered
even though a quantified lemma it already known. In this case, the
instance should be added to a corresponding context, even though the
lemma is not new.
