Insights from the NeurIPS 2021 NetHack Challenge

Abstract

In  this  report,  we  summarize  the  takeaways  from  the  first  NeurIPS  2021  NetHackChallenge.   Participants  were  tasked  with  developing  a  program  or  agent  that  can  win(i.e.,  ‘ascend’ in) the popular dungeon-crawler game of NetHack by interacting with theNetHack Learning Environment (NLE), a scalable, procedurally generated, and challengingGymenvironment for reinforcement learning (RL). The challenge showcased community-driven progress in AI with many diverse approaches significantly beating the previously bestresults on NetHack.  Furthermore, it served as a direct comparison between neural (e.g.,deep  RL)  and  symbolic  AI,  as  well  as  hybrid  systems,  demonstrating  that  on  NetHacksymbolic bots currently outperform deep RL by a large margin.  Lastly, no agent got closeto winning the game, illustrating NetHack’s suitability as a long-term benchmark for AIresearch
