Abstract: A multiplayer collaborative task assurance method is provided. Parameter information of a virtual device is acquired as a first parameter information, and input into a pre-trained target model to obtain model results. A model result with a highest priority is acquired as a first model result and is sent to the collaborative client. The collaborative client updates a local model to obtain an updated result. Feedback information is sent to the server based on the updated result. Whether a proportion of the approved opinion in the feedback information exceeds a preset value is determined; if yes, the parameter information in the virtual device is updated. Whether the first model result is correct is determined; if yes, a confirmation message is sent to the collaborative client to continue the multiplayer collaborative task.
