A program based on policy mode consists of at least two parts. The first part is a set of policy classes, which encapsulate specific algorithms and are responsible for specific calculation processes. The second part is the environment class Context, which receives the client's request and then delegates the request to a policy class. We first use traditional object-oriented to implement it.

External communication with a subsystem must be conducted through a unified facade object. The facade mode provides a high-level interface, making the subsystem easier to use. Each subsystem has only one facade class, and this facade class has only one instance, that is, it is a singleton pattern. But the whole system can have multiple facade classes.

Not only that, according to the intuitive feelings of the reporters of the NPC and CPPCC, the proportion of female reporters is far higher than that of men. In 2013, the number of reporters from Nanjing Metropolis Daily who went to Beijing was 11, and the ratio of men to women was miraculous 3: 8. Some people joked that the news war between the NPC and CPPCC used women as men.
For example, the Korean drama "Mist", which recently caught fire, is vividly unfolded in the story of heroine Gao Huilan. In order to obtain news, she is diabolical, selfish and does everything she can, but at the same time, she is extremely rational and uncompromising for her news ideal.
1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.

This trip to the countryside gave me a deeper understanding of the basic situation in our country's countryside. We all went to places with high incidence of cancer, and personality is Shexian, the place with the highest adjusted mortality rate in the country. After investigation, the local environmental pollution is relatively serious. Although there are "Top Ten Well-off Villages" and more factories have brought economic benefits, they have also brought great pollution to the local environment. In the past, farmers had to drink polluted water. At the moment, deep wells have been drilled to drink clean and sanitary water. However, many factors in various fields still cause the high incidence of cardiovascular diseases and cancer in the area. Some families have seen the phenomenon of "poverty due to illness and returning to poverty due to illness". The implementation of the national new rural cooperative medical system has effectively relieved the economic pressure of patients' families. To a certain extent, it has curbed the phenomenon of returning to poverty due to illness and causing poverty due to illness, promoted the development of rural health services, promoted the change of farmers' concept of seeking medical treatment, and also enhanced the image of the Party and the government for private affairs. However, many farmers still do not know enough about this policy.
