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
