game strategy

Define: define a family of algorithms, encapsulate each one, and make them interchangeable. Strategy lets the algorithm vary independently from clients that use it.I. Strategy Mode The purpose of the rule mode is to encapsulate each algorithm into an independent class with a common interface for mutual replacement. The policy mode allows the algorithm to change without affecting the client. Suppose we want

Introduction to Strategy, strategyI. Introduction to Strategy The rule mode is the action mode. Behavior mode:Defines the responsibilities of each object and the communication mode between objects. It standardizes the call and data transmission methods between objects. The rule mode is suitable for situations where algorithms change frequently. The algorithm changes will not affect the customers who use the

get a ticket to get rid of the worry". The advantage of students is that they have a real student ID card when they go home during the cold and summer vacations, A half price can be off without a half price, which is more cost-effective than taking a car home. However, we cannot ignore the truth behind the cheap price. All kinds of ticket snatching are waiting for midnight, so sometimes we have to go home like a night owl. In comparison, for students, the way to go home is dominated by trains a

conditional statements, the code will be easier to manage, and future maintenance of the code will be much easier. The goal now is to refer these validation checks to various policy classes so that they can be reused in proxy methods and other methods. Each validation takes the input value out of the text box, validates it according to the policy that is required by H, and returns a bool value. If the return fails, a Nserror instance is also returned. The returned nserror can explain the caus

Evolutionary strategy (Evolution strategy) It is recommended that before understanding ES to ensure that the idea of genetic algorithm has a certain understanding, in the comparison of learning more efficient, paste a previously written genetic algorithm to introduce the same as the genetic algorithm: are optimized by evolutionary theory, that is, genetic information is used to inherit and mutate the survi

Summary of some strategies of PHP program efficiency optimization, PHP Efficiency Strategy Summary 1. In the case of file_get_contents instead of file, fopen, feof, Fgets and other series of methods, try to use file_get_contents, because he is much more efficient! But pay attention to file_get_ Contents PHP version problem when opening a URL file; 2. As much as possible file operation, although PHP file operation efficiency is not low;3. Optimize the

Introduction: Sometimes, the presentation layer of an application must handle coordination between multiple API layer method invocations to complete a single transactional unit of work. In this article, the transaction policy family author Mark Richards will discuss client-side choreography (clients orchestration) transaction policies and explain how to implement it in the Java™ platform. If you have been reading this series, you should know that you now need an effective and reliable transacti
