Аннотация:
Tracing and analysing the responsibility for unsafe outcomes of actors’ decisions in multi-agent settings have been studied in recent years. These studies often focus on deterministic scenarios and assume that the unsafe outcomes for which actors can be held responsible are actually realized. This paper considers a broader notion of responsibility where unsafe outcomes are not necessarily realized, but their probabilities are unacceptably high. We present a logic combining strategic, probabilistic and temporal primitives designed to express concepts such as the risk of an undesirable outcome and being responsible for exceeding a risk threshold in one-shot games. We demonstrate that the proposed logic is (weakly) complete, decidable and has an efficient model-checking procedure. Finally, we define a probabilistic notion of responsibility and study its formal properties in the proposed logic setting.
