The strategy of the Red Ocean is mainly to compete in the already known market space. Here, you are cheaper than your opponent, or you can achieve a more differentiated strategy than him, the game rules have been set. The blue ocean strategy is not limited to the existing industrial boundaries, but to break such boundary conditions. Sometimes the blue ocean is op

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

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

Brief introduction Policy is one of the behavioral patterns, which allows the behavior or algorithm of an object to change at run time, using different algorithms to achieve the same result or purpose. Implementation level, define an abstract algorithm interface, and then according to the specific algorithm to define different classes to implement the interface, the invocation of different implementations of the instances can be replaced with each other. The policy pattern applies to multiple cl

Design Mode (18) Strategy Mode strategy (object behavior type) 1. Overview Similar situations are often encountered in software development. There are multiple algorithms or policies for implementing a function. We can select different algorithms or policies based on different environments or conditions to complete this function. Such as search and sorting. A common method is hard coding in a class. To pr

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

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

GOF "design pattern" is described in the strategy mode: Define a series of algorithms that encapsulate them one by one and make them interchangeable with each other. The strategy mode allows the algorithm to vary independently from the customer who uses it. The strategy model is based on the following principles: 1 Each object is an individual with responsibil

9.1 informatization strategy and enterprise management strategy Different enterprises have different focuses on their business strategies in different periods. Therefore, the demands for informatization vary at different stages. If the enterprise's strategic focus is on product upgrades, the application of CAD, PDM, Capp, GT, GAM and other information technologies becomes more urgent. If the enterprise fo
