Proceedings International Workshop on Interactions, Games and Protocols
  The focus of the iWIGP workshop is the interrelation between interactions, games and protocols. How does computer science deal with nondeterministic interactions where the actions a system takes are not (completely) determined by the interactions the system is involved in? In computer science, nondeterministic interactions are usually described by protocols. However, these interactions can also be viewed as games. As to be expected, games have become an increasingly important modeling tool wherever nondeterministic interactions are involved -- from foundations in game semantics and reactive systems to applications in communication protocols and electronic business applications. The goal of this workshop has been to bring researchers from industry and academia together and to explore how a better understanding of the interrelation between interactions, games and protocols leads to better-designed and more reliable nondeterministic interacting systems.   iWIGP 2011 was collocated with ETAPS 2011 in Saarbruecken, Germany. The programme consisted of three invited talks, by Kim Larsen, Marielle Stoelinga and Viktor Kuncak, and five refereed papers, selected by a strong programme committee of international reputation. The refereed papers are contained in this volume.
