Instead, it operates in cycles of iterative deepening. Selective Search and Heuristics Blindly searching all moves to the same depth is prohibitively expensive, so Stockfish employs sophisticated selective search algorithms.
Stockfish Magic Bitboards Explained Simply
It represents the board using a technique called "bitboards," which use 64-bit integers to map the location of pieces. The Core Engine: Alpha-Beta Search and Beyond At the heart of Stockfish lies a highly optimized implementation of the minimax algorithm, enhanced with alpha-beta pruning.
The Iterative Deepening Loop Stockfish does not conduct a single, massive search and then stop. Neural Network Integration Recent versions of Stockfish have been revolutionized by the integration of neural networks.

Additionally, it uses the results from previous depths to craft a more effective "aspiration window" for the next search, drastically reducing the number of nodes that need to be re-evaluated. King Safety: A significant weight is given to the vulnerability of the king, considering factors like pawn shields and attacking pieces.
