Abstract

In this note, we present a mechanization of Johnson’s procedure. We first specify the scheduling problem, we are concerned with. Then, we formalize Johnson’s procedure and prove an invariant. Thanks to this invariant, we prove the correctness of Johnson’s procedure and its optimality. Last, also thanks to the invariant, we elaborate a concurrent version of Johnson’s procedure which is correct by construction. We use the Python language for expression and experimentation purposes. The Isabelle HOL assistant theorem prover is used for validating the correctness.
