case class ExistsLeftTactic(mode: TacticApplyMode = UniqueFormula, eigenVariable: Option[Var] = None) extends StrongQuantTactic with Product with Serializable
Decomposes an existential quantifier in the antecedent of a goal.
- mode
How to apply the tactic: To a specific label, to the only fitting formula, or to any fitting formula.
- eigenVariable
If Some(v), the rule will attempt to use v as the eigenvariable. Otherwise it will automatically pick one.
