Goals

TODO

• typing and translation Ast -> Term (from mc2?)

• main executable for SMT solver

• theory of boolean constructs (on the fly Tseitin using local clauses)

• make CC work on QF_UF

  • internalize terms on the fly (backtrackable)
  • basic notion of activity for ite?

• have CDCL.push_local work properly

• remove tseitin lib

• write Shostak theory of datatypes (without acyclicity) with local case splits

• design evaluation system (guards + eval_bool:(term -> bool) option in custom TC)

• compilation of rec functions to defined constants

• Shostak theory of eq-ℚ

• datatype acyclicity check

• abstract domain propagation in CC

• domain propagation (intervals) for ℚ arith

• full ℚ theory: shostak + domains + if-sat simplex

Main goals

• Add a backend to send proofs to dedukti
  • First, pure resolution proofs
  • Then, require theories to output lemma proofs for dedukti (in some format yet to be decided)
• Allow to plug one's code into boolean propagation
  • react upon propagation (possibly by propagating more, or side-effect)
  • more advanced/specific propagation (2-clauses)?
  • implement 'constraints' (see https://www.lri.fr/~conchon/TER/2013/3/minisat.pdf )

Long term goals

• max-sat/max-smt
• coq proofs ?

Done

• base types (Term, Lit, …)
• theory combination
• basic design of theories
