# explorationParameter A value that influences whether the strategist searches more broadly or more deeply for winning game model states. ``` var explorationParameter: Int { get set } ``` ## Discussion When you call the [`bestMoveForActivePlayer()`](/documentation/GameplayKit/GKStrategist/bestMoveForActivePlayer()) method, the Monte Carlo strategist performs an iterative process of randomly choosing moves, searching for a sequence of moves that ends in a win for the current player. At each step in this process, the strategist chooses whether to try a different move or to continue examining the current sequence of moves. Higher values favor *exploration—that is,* the strategist becomes more likely to try different moves on each turn. Lower values favor *exploitation—that is,* the strategist becomes more likely to follow a sequence of moves to a possible endgame. The default value of 4 tends to balance exploration and exploitation. For best results, experiment with different values to find one that provides a style and difficulty of gameplay you prefer for your game. --- Copyright © 2026 Apple Inc.
