Author: Lucas Dixon Title: IsaPlanner: A proof planning framework for Isabelle Abstract: We introduce our work on the development of a proof planner for Isabelle and highlight some recent developments. The central aim of this work is to improve automation in Isabelle by employing techniques, such as rippling, from the paradigm of proof planning. A second goal of our work is to use the correspondence between proof plans and Isar proof scripts to provide tools for the automatic generation and manipulation of proof scripts.
