With the development of communication and sensor technology, wireless sensor network (WSN) ,which integrate data acquisition, processing and transmission, communication, cause the attention of people. Limited by node's energy, we should consider node localization algorithm, when study wireless sensor network; There are two kind of localization algorithm: based on range finder technology and without...
Police Patrol is a very useful method for managing the social security. Many researches focus on how to obtain the best strategy for police patrol. We got this research topic from The Sixth National Post-Graduate Mathematical Contest in Modeling. In the proposed approach, Greedy Policy and Randomized Strategy are combined with Genetic Algorithm to solve these problems, simulation result shows the...
