…eanprover#6618) This PR implements exhaustive offset constraint propagation in the `grind` tactic. This enhancement minimizes the number of case splits performed by `grind`. For instance, it can solve the following example without performing any case splits: ```lean example (p q r s : Prop) (a b : Nat) : (a + 1 ≤ c ↔ p) → (a + 2 ≤ c ↔ s) → (a ≤ c ↔ q) → (a ≤ c + 4 ↔ r) → a ≤ b → b + 2 ≤ c → p ∧ q ∧ r ∧ s := by grind (splits := 0) ``` TODO: support for equational offset constraints.
