This paper shows how a symmetric and non-deterministic cut elimination procedure for a classical sequent calculus can be faithfully simulated using a non-deterministic choice operator to combine different ‘double-negation’ translations of each cut. The resulting interpretation of classical proofs in a λ-calculus with non-deterministic choice leads to a simple proof of termination for cut elimination.
