4.3 Preferences for the Auto-prover The auto-prover can be configured by means of a preference page, which can be obtained as follows: press the ”Window” button on the top tooolbar. On the coming menu, press the ”Preferences” button. On the coming menu, press the ”Event-B” menue, then the ”Sequent Prover’, and finally the ”Auto-Tactic” button. This yields the following window: On the left part you can see the ordered sequence of individual tactics composing the auto-prover, whereas the right part contains further tactics you can incorporate in the left part. By selecting a tactic you can move it from on part to the other or change the order in the left part. 30
5 The Proof Obligation Explorer The ”Proof Obligation Explorer” window has the same main entries as the ”Project Explorer” window, namely the projects and its components (context and machines). When expanding a component in the Proof Obligation Explorer you get a list of its proof obligations as generated automatically by the Proof Obligation Generator: As can be seen in this screen shot, machine ”celebrity 1” of project ”celebrity” is expanded. We find seven proof obligations. Each of them has got a compound name as indicated in the tables below. A green logo situated on the left of the proof obligation name states that it has been proved (an A means it has been proved automatically). By clicking on the proof obligation name, you are transferred into the Proving Perspective which we are going to describe in subsequent sections. 31
