[L4] ================================================ AMAST Links 03 01 Formal Verification of Algorithm W: The Monomorphic Case Dieter Nazareth and Tobias Nipkow A formal verification of the soundness and completeness of Milner's type inference algorithm W for simply typed lambda-terms is presented. Particular attention is paid to the notorious issue of "new" variables. The proofs are carried out in Isabelle/HOL, the HOL instantiation of the generic theorem prover Isabelle. The paper documents HOL's subtheory MiniML and is available via URL: http://www4.informatik.tu-muenchen.de/~nipkow/pubs/W0.html
