First of all: This article is not a discussion of marital problems, but an example of the marriage problem of daily life as an illustration of an interesting algorithm:Gale-shapley algorithm (delay recognition algorithm), if you feel disappointed, I will express my apologies, but if you are interested, It is recommended that you take a look, especially for a friend who is not yet a GF or BF, and a friend who is about to get married, you will find it useful in explaining the implementation of the

The algorithm has good performance in allocation and release time, which makes the distribution of free partitions more even, but it is not easy to retain large idle partitions.

Let's go back to one day at the beginning of the 20th century. Imagine that Coca-Cola's partner A is busy sorting out the sales data for the day, classifying the customer into categories, and sorting them by order size, count how many bottles of drinks are sold today.

What do you need to discover if a known business partner has a known E-commerce gateway? However, this is the case where all the information is known by default. When you want to find out which business partner has some kind of service, th
configure WSFC.Windows Server failover clustering provides the ability to combine multiple computer nodes (physical and virtual) to provide services for high availability. Applications are server software, such as SQL Server or exchange, and we want to be able to run on any node.

software, such as SQL Server or exchange, and we want to be able to run on any node. Make your app highly available by rendering a virtual access point that includes a unique IP address and a unique computer name or "virtual network name" to the client. This address and virtual name become resources in the application group and are passed between participating nodes, such as tokens. A serious hardware failure of the active computer node will result in the loss of the group service running on th
The memory pool system and the memory heap allocation system are implemented in InnoDB, which is divided into three parts in InnoDB memory management system: basic memory block allocation management, memory partner allocator and memory heap allocator. InnoDB The primary purpose of defining and implementing a memory pool is to provide memory usage and efficiency to prevent memory fragmentation and memory allocation tracking and debugging. Let's take a

First, we need to know that C # is an object-oriented language evolved from C and C ++, which relies on. NET Framework.. NET Framework provides a powerful code library for its calling. C # Language depends on. NET Framework because C # source code is only compiled by the compiler (VS or VCE) and becomes a Common Intermediate Language. Generally, the. exe or. dll file we use is also called an assembly. When
