Appendix to "Faster Smarter Proof by Induction in Isabelle/HOL"

We present sem_ind, a recommendation tool for proof by induction in Isabelle/HOL.
Given an inductive problem, sem_ind produces candidate arguments for proof by induction, and selects promising ones using heuristics.
Our evaluation based on 1,095 inductive problems from 22 source files shows that sem_indimproves the accuracy of recommendation from 20.1% to 38.2% for the most promising candidates within 5.0 seconds of timeout compared to its predecessor while decreasing the median value of execution time from 2.79 seconds to 1.06 seconds.
