Reproducibility Variable Result LLM Response
Research Type Theoretical This paper studies the problem of the existence of such an announcement in the context of model-preference definable revision operators. First, we provide two characterisation theorems for the existence of announcements: one in the general case, the other for total preorders. Second, we exploit the characterisation theorems to provide upper complexity bounds. Finally, we also provide matching optimal lower bounds for the Dalal and Ginsberg operators.
