A Recognition Approach for Adversarial Planning Based on Complete Goal Graph

Based on classical plan graph and goal graph, complete goal graph (CGG) is constructed against the characteristics of adversarial domain. The complete goal graph makes the action relate with its goal directly, which is more efficient to recognize adversarial goals. The conception of complete degree of goals will be put forward to distinguish adversarial high level goals. Then, a deep research is done on adversarial plan recognition algorithm based on CGG, which not only can predict adversarial next step action, but also can recognize adversarial goals in different levels with complete degrees. The research is of great significance for the plan recognition problem of uncontrollable and nondeterministic domain such as contest robot, information security, business strategy, game role design and etc.
