Incremental Recompilation of Knowledge

d Abstract) Goran Gogic l, Christos H. Papadimitriou', and Martha Sideri2 : Approximating a general formula from above and below by Horn formulas (its Horn envelope and Horn core, respectively) was proposed in [SIC] as a form of "`knowledge compilation," supporting rapid approximate reasoning; on the negative side, this scheme is static in that it supports no updates, and has certain complexity drawbacks pointed out in [KPS]. On the other hand, the many frameworks and schemes proposed in the literature for theory update and revision are plagued by serious complexity-theoretic impediments, even in the Horn case, as was pointed out in [EGZ?] and the present paper. More fundamentally, these schemes are not inductive, in that they lose in a single update any positive properties of the represented sets of formulas (small size, Horn, etc.). In this paper we propose a new scheme, incremental recompilation, combining Horn approximation and model-based updates; this scheme is ind...
