Navigate Acquire Interact Learn
NAIL is a general game-playing agent designed for parser-based interactive fiction games (Hausknecht et al. 2019). NAIL employs a simple heuristic: examine the current location to identify relevant objects, interact with the identified objects, navigate to a new location, and repeat. Though simple, this loop proves effective across a wide variety of games.
NAIL won first place in the 2018 Text-Based Adventure AI Competition (Atkinson et al. 2018), where it was evaluated on a set of twenty unknown parser-based IF games.
