Game behavior decision-making method and device and related equipment thereof

The invention discloses a game behavior decision-making method, and the method comprises the steps: collecting known information of a current game subject when a decision-making instruction is received; processing the known information by using a preset hidden information prediction model to obtain hidden information combinations and existence probabilities of the hidden information combinations;screening from all the hidden information combinations to obtain hidden information combinations of which the existence probability exceeds a preset existence probability; performing game tree construction on the screened hidden information combinations to obtain an optimal game behavior. According to the invention, the game behavior decision-making method can effectively improve the decision-making efficiency of the game behavior in the game process, and also improves the accuracy of the game result. The invention further discloses a game behavior decision-making device and system and a computer readable storage medi
