A multi-modi Proof Planner

Proof planning is a novel knowledge-based approach for proof construction, which supports the incorporation of mathematical knowledge and the common mathematical proof techniques of a particular mathematical eld. This paradigm is adopted in the mega proof development system, to provide support for the user. A considerable part of the proof construction and even sometimes the whole work can be undertaken by a proof planner. In the mega project we are investigating the aspect of computation under bounded resources in mathematical theorem proving. The relevant resources are, in addition to time and memory space, user availability as well as the frequency of user interaction. At this issue, the proof planner of mega is conceived in such a way that it has a resource-adaptive behaviour. This property of the planner is achieved by a planner modus which deenes the planner behaviour depending on which and how many resources are available. In this paper, we describe the diierent modi of the mega planner and highlight the main aspects of resource-adaptivity.
