This engineering project asks the student to write code to analyse the “theory” files generated by the HOL4 system to detect redundant theorems. These are those that are never used (and might be good candidates for deletion).
This project will require the student to write code to parse and analyse a somewhat complicated file format, to analyse the resulting graph of links between theorems, and to then report the results. In addition to flagging unused theorems, it might be nice to also produce a graph showing how results build on other theorems.
