elevator blueprint

Recently want to study in detail the elevator scheduling algorithm, but the content involved too much, there is no time. About the types of elevator algorithms:Http://www.cnblogs.com/jianyungsun/archive/2011/03/16/1986439.htmlThen I can only look at the simple.This is a topic in the beauty of programming:A total of 6 elevators are in a building. At rush hour, everyone on each floor is up and down, and the

developers are often unable to control the dependencies of those libraries. So the problem arises when the two libraries that an application uses have different and incompatible internal dependencies. For example, one library might require ASM 3.0, and another library used by the same application might require ASM 2.0. To resolve this problem, you typically need to change the code. In general, these two problems are usually solved in Java EE, so why endure the problems that OSGi can solve? Th

Tags: paging mysql performance optimizationPaging technology is very common in the development, I just went to the company to do two projects are used in the paging technology, so think about the paging technology in-depth exploration. There are several common paging methods: Escalator mode Escalator mode in the navigation usually only provide the previous page/next page of these two modes, some products do not even provide a previous page function, only provide a "more/more" wa

Unreal Engine provides a complete set of animation design system, from basic animation import, to the final character animation control, the process is complete and mature, easy to get started. The following first introduced from the macro-UE4 animation system, and then in-depth introduction of several functional modules.first, the overall introductionThe following image is translated from the official document, which introduces the context of the animation function as a whole and is simple and

parameterless member function:myuobject* MyObj = NULL; // This assumes the creation of Myuobject if (MYOBJ) { = Mygamemode->oninitialize (). Adduobject (MYOBJ, myuobject::testfun); } Note: Any uobject normal function can be set to the callback function of the event, but if the function is ufunction, you need to replace Adduobject with addufunction.3, triggering event, here is assumed to be triggered in Beginplay:void Amygamemode::beginplay () { initevent.broadcast (); } 4, r

new technology, there are some things to do and not to do, which is also known as best practice for architects, developers, and deployment personnel. OSGi technology has been in use for more than 10 of years, and there have been many best practices at that time. This article describes the authoring of OSGi applications and Integration Service Component Architecture (SCA)-related master for OSGi applications feature of WebSphere application Server To best practice. Some of these are common OSGi

" need to know exactly how they will connect. This is not a problem that can be easily solved. A comprehensive hierarchical model (generally called a blueprint) that represents the current and expected status can effectively support the "Intermediate encounter" method. This method requires clear tracing from the top-down method, and the blueprint can provide this. With such a

It's not that the two of them have a long angle on their heads. It's very strange. You need to understand why you need to separate them. First, let me tell a story.The business building of our company is located on the third floor, the second floor is simulated, and the third floor is digital. There is only one elevator
