DECISION MODEL TRAINING METHOD AND APPARATUS, DEVICE, STORAGE MEDIUM, AND PROGRAM PRODUCT

A decision model training method and apparatus are provided. The method may include: obtaining model pools of virtual characters, the model pools including decision models corresponding to the virtual characters, and the decision models being used for indicating battle policies adopted by the virtual characters in battles; updating and training nth decision models of the virtual characters based on battle data of a battle between the virtual characters in an nth iteration process to obtain n+1th decision models of the virtual characters; adding the n+1th decision models to the model pools of the corresponding virtual characters; and determining, based on an iterative training end condition being satisfied, decision models obtained by the last round of training in the model pools as target decision models of the virtual characters.
