Abstract

Interactive theorem provers require input from users to guide the proof process. Some theorems can be complicated, making it difficult to decide which direction to take at a specific point within a proof. PG Tips is a recommender system that has been incorporated into the theorem prover Isabelle’s graphical user interface, Proof General, in order to assist users.
Recommender systems are used, in a variety of situations, to provide predictions based on information supplied by a user. In this case, PG Tips is used to suggest possible proof steps based on the analysis of previous proofs. It is hoped that the creation of such a system will help users in finding proofs and accelerate the proof authoring process.
