“…Different approaches of deontic logic, alternative to SDL, have been studied in the past 6 decades including imperative logic [6,7], dynamic deontic logic [2,8], deontic STIT logic [9,10], input/output logic [11], deontic default logic [12,13] and deontic defeasible logic [14,15]. Those results are summarized in the handbook of deontic logic [16,17].…”
