def Duper.MClause.abstractAtPos! (c : MClause) (pos : ClausePos) : Lean.MetaM MClause

This function acts as Meta.kabstract except that it takes a ClausePos rather than Occurrences and expects the given expression to consist only of applications up to the given ExprPos. Additionally, since the exact position is given, we don't need to pass in Meta.kabstract's second argument p

Returns the list of literals (that satisfy the provided filter_fn) for which the size difference between the lhs and rhs is maximal. Note: For getMaxDiffLits, the filter_fn takes in both the lit and its index because filtering by index is more convenient for some selection functions.

def Duper.MClause.isMaximalLit (ord : Lean.Expr → Lean.Expr → Bool → Lean.MetaM Comparison) (alreadyReduced : Bool) (c : MClause) (idx : Nat) (strict : Bool := false) : Lean.MetaM Bool

Determines whether c.lits[idx]! is maximal in c. If strict is set to true, then there can be no idx' such that c.lits[idx]! and c.lits[idx']! are evaluated as equal by the comparison function

Equations

• One or more equations did not get rendered due to their size.

def Duper.MClause.canNeverBeMaximal (ord : Lean.Expr → Lean.Expr → Bool → Lean.MetaM Comparison) (alreadyReduced : Bool) (c : MClause) (idx : Nat) : Lean.MetaM Bool

Returns true if there may be some assignment in which the given idx is maximal, and false if there is some idx' that is strictly greater than idx (in this case, since idx < idx', for any subsitution σ, idx σ < idx' σ so idx can never be maximal)

Note that for this function, strictness does not actually matter, because regardless of whether we are considering potential strict maximality or potential nonstrict maximality, we can only determine that idx can never be maximal if we find an idx' that is strictly gerater than it
