COMPUTER-IMPLEMENTED METHODS OF EVALUATING TASK NETWORKS

Abstract:

A computer-implemented method of evaluating a task network. The task network comprises primitive tasks which represent actions, compound tasks which represent a plurality of tasks, goal tasks which represent desired goals, and one or more constraints associated with the tasks of the task network. A library of network fragments is provided, where each network fragment comprises a plurality of tasks and one or more associated constraints, and a plurality of network fragments of the library of network fragments have associated with them an abnormality level. One or more network fragments of the library of network fragments are matched with a plurality of tasks and one or more associated constraints of the task network. A normality score is determined for the task network using the abnormality levels associated with the one or more matching network fragments.
