Center node: "abstract model repair"
  Abstract: Given a Kripke structure M and CTL formula $\varphi$, where M does not#N#satisfy $\varphi$, the problem of Model Repair is to obtain a new model M' such#N#that M' satisfies $\varphi$. Moreover, the changes made to M to derive M'#N#should be minimum with respect to all such M'. As in model checking, state#N#explosion can make it virtually impossible to carry out model repair on models#N#with infinite or even large state spaces. In this paper, we present a framework#N#for model repair that uses abstraction refinement to tackle state explosion.#N#Our framework aims to repair Kripke Structure models based on a Kripke Modal#N#Transition System abstraction and a 3-valued semantics for CTL. We introduce an#N#abstract-model-repair algorithm for which we prove soundness and#N#semi-completeness, and we study its complexity class. Moreover, a prototype#N#implementation is presented to illustrate the practical utility of#N#abstract-model-repair on an Automatic Door Opener system model and a model of#N#the Andrew File System 1 protocol.
