Knowledge State Reconsideration: Hindsight Belief Revision

AAAI Conferences 

If p was not yet added to the base, and we had an IAT-preference ordering that ordered the beliefs in the following sequence from most to least preferred: p, p q, p r, m r, s t, w v, w k, p v, z v, n, r, w, s, v, m, z, q, t, k, then the optimal base would be B1 {p, p q, p r, m r, s t, w v, w k, p v, z v, n, w, s, m, z}. The semi-revision addition of p (preferred over p) followed by reconsideration is described in Example2.
