@ -17,39 +17,6 @@ Notes:
For DIMACS input it produces DRAT proofs.
For SMT extensions are as follows:
Input assertion:
i <literal>* 0
Assertion (true modulo a theory):
a [<theory-id>] <literal>* 0
The if no theory id is given, the assertion is a tautology
modulo Tseitin converison. Theory ids track whether the
tautology is modulo a theory.
Assertions are irredundant.
Bridge from ast-node to boolean variable:
b <bool-var-id> <ast-node-id> 0
Definition of an expression (ast-node):
e <ast-node-id> <name> <ast-node-id>* 0
Redundant clause (theory lemma if theory id is given)
[r [<theory-id>]] <literal>* 0
Declaration of an auxiliary function:
f <smtlib2-function-declaration> 0
Garbage collection of a Boolean variable:
g <bool-var-id> 0
Available theories are:
- euf The theory lemma should be a consequence of congruence closure.
- ba TBD (need to also log cardinality and pb constraints)
Life times of theory lemmas is TBD. When they are used for conflict resolution
they are only used for the next lemma.
