Game-playing demonstrates that neural networks achieve superhuman performance through two distinct paradigms — AlphaGo (2016) combined deep neural networks with tree search to master Go, while a transformer achieved grandmaster-level chess (Elo 2895) using pure static evaluation without any search — suggesting that both hybrid (neural+search) and pure neural approaches can reach expert-level game play, with each paradigm's dominance depending on the game's computational structure.

Justifications

SL — Two superhuman game-playing achievements use opposite approaches (hybrid search vs. pure neural), revealing that search may be replaceable by sufficient model capacity

Antecedents (all must be IN):

IN ml-alphago-2016-deep-nn-tree-search — AlphaGo (Silver et al., 2016) demonstrated deep neural networks combined with tree search mastering the game of Go
IN transformer-chess-elo-2895-no-search — A transformer using only static evaluation (no Minimax search) achieved grandmaster-level chess with an Elo rating of 2895.

Dependents

These beliefs depend on this one:

IN game-playing-validates-search-replaceability-by-capacity — Game-playing empirically demonstrates that explicit search (tree search, Monte Carlo methods) can be complemented or replaced by sufficient model capacity — AlphaGo combined deep neural networks with tree search, while a later transformer achieved grandmaster chess through pure static evaluation — suggesting that the search-vs-capacity tradeoff may be influenced by hardware-driven architecture selection, where increasing compute can reduce the need for explicit search, though both hybrid and pure neural paradigms remain viable depending on the game's computational structure.
