Approximations of Modal Logic K

Inspired by the recent work on approximating classical logic, we present a procedure that approximates the modal logic K by determining a maximum limit of introspection. This procedure has a clear semantics and a natural proof theory in the context of Massacci's modal Single Step Tableaux (SST). Key words: Approximated Inference, Modal Logic, Approximations of Modal Logic.
