“…Often triggered directly by the initial work on dynamic-epistemic logic and sabotage modal logic, many further logics of graph modifiers have been proposed in the recent literature than what we have covered here. Besides the above mentioned series of work [1,3,2,4], relevant systems include local and global graph modifiers [8], dynamic epistemic modifiers [11,10], dynamic modal logic DML [15], arrow logic [31], logics of copy and remove [6], the logic of preference upgrade [51], and general dynamic dynamic logic [25]. 30 Instead of discussing the above terrain in detail, we give a small 'expressiveness map' based on what can readily be observed, and on what authors have claimed.…”
