Game semantics and abstract machines

Abstract

The interaction processes at work by M. Hyland and L. Ong (1994) (HO) and S. Abramsky et al. (1994) (AJM) new game semantics are two preexisting paradigmatic implementations of linear head reduction: respectively Krivine's abstract machine and Girard's interaction abstract machine. There is a simple and natural embedding of AJM-games to HO-games, mapping strategies to strategies and reducing AJM definability (or full abstraction) property to HO's one.
