Abstract: We present the first formal verification of approximation algorithms -for NP-complete optimization problems: vertex cover, independent set, +for NP-complete optimization problems: vertex cover, set cover, independent set, load balancing, and bin packing. The proofs correct incompletenesses -in existing proofs and improve the approximation ratio in one case.
