The user does not have to script the proof search by hand. The tools draw on very large formal libraries, and the name comes from Sledgehammer for Isabelle and HOLyHammer for HOL Light. ## All works 21 works of theirs in our library, the most cited first; 2 with a page here, the others link their original until we summarise them. 1. **[DeepMath - Deep Sequence Models for Premise Selection ↗](https://arxiv.org/abs/1606.04442) arXiv:1606.04442 · no summary yet**Alex A.
