A kind of alpha-beta search algorithm based on region-divided checkerboard for the game of Amazons was used to improve the efficiency. Hierarchy searching is adopted in this approach. Searching is firstly carried in the divided regions, then the searching result of the whole checkerboard is gotten according to those valued of various regions. The evaluation and integration of divided regions are also...
A separation method of the vibration signal based on improved fast ICA was proposed. It adopted the steepest descent method to improve the convergence rate. Improved fast ICA method is applied to separation of vibration signal from the train's running gear. Separation results proved that the method is feasible and effective. The method is contributive and instructional to train's running gear vibration...
Access control policy is a set of rules, which control and constraint the communication and access between all kinds of entities. Policy conflict is one of the outstanding issues related to policy management. Nevertheless current access control policy conflict detection algorithms are completely dependent on policy specification and the applications, which make these algorithms non-reusable and non-extensible...
