Decision model training method and device, equipment, storage medium and program product

The embodiment of the invention discloses a decision model training method and device, equipment, a storage medium and a program product, and belongs to the field of artificial intelligence. The method comprises: obtaining a model pool corresponding to each virtual character, the model pool including each decision model corresponding to the virtual character, and the decision model being used for indicating a battle strategy adopted by the virtual character during wartime; in the nth iteration process, on the basis of game data in the game process between the virtual roles, updating and training the nth decision model of each virtual role to obtain an (n + 1) th decision model of each virtual role, and respectively adding each (n + 1) th decision model into a model pool of the corresponding virtual role; and determining the decision model obtained by the last round of training in the model pool as a target decision model of the virtual character under the condition that an iterative training ending condition
