Using STIT theory to talk about strategies

International audience; This chapter gives an overview of logical theories of ‘seeing-to-it-that’, commonly abbreviated stit, and focusses on the notion of ‘strategy’ as used in their semantics. The chapter covers both ‘one-step’ strategies (i.e., atomic actions) and long-term strategies and explains how they give semantics to different stit languages. Furthermore, the chapter discusses how extensions with epistemic operators can be used to clarify the problem of uniform strategies. Finally, it is shown how strategic stit theories disambiguate some seemingly paradoxical observations recently made in the context of logics of strategic ability (ATL).
