Could you build this?
No This is a formal mathematical proof written in Lean 4 verifying complex graph theoretical bounds. Formalizing novel academic mathematical proofs requires deep research-level domain expertise in both interactive theorem proving and advanced theoretical computer science.
What it would actually take: Building this requires formal methods expertise in Lean 4 and Mathlib along with advanced research knowledge in graph theory and algorithms (specifically directed SSSP bounds). The author must translate intricate mathematical proofs into formal type theory, constructing lemmas, invariants, and tactic scripts that satisfy the Lean kernel.
