defined in the following way--node *son[2]. So, Son[0] is the left child, Son[1] is the right child. At this point, you can write the code of the left and right operations into a paragraph in the implementation, using a bool variable to differentiate it. Therefore, the code will be less than half! I say that people are certainly confused, no nonsense, directly on the code, we have a closer look at the code to understand. Title: Sjtuoj 1221. Refreshing version: No. Because the Splay implementati

For more information, see. LoadRunner's script language is actually no different from C. Many of his internal mechanisms are implemented by C.It is just a "Class C"So I will analyze it from several aspects.1: defining constant variables is the same as C2: The parameters of the LR function are a little different from those of C. In LR, the variables of C are different from those of LR.No C variable can be di

I used to read other people's blogs and never wrote them myself. Some time ago, I suddenly saw some key points about writing Technical blogs, I would also like to write my own blog (although not very professional), not only to record the problems found and solved, but also to record the growth of my work. Why start with LR? Let's talk about my "affinity" with LR-when I first joined the project team, the

writing this article is to make a memorandum . The reason is very simple, is three years ago used for a period of time LR, thought this test will pro, can not think, even the simplest number of concurrent users forget where set up, so in view of this, only sense to do the record of ' necessity '. So the contents of this article both notes and actual combat in a, hehe. Well, crap less, let's go!First, I'm going to build a test environment locally, and

Discretization of continuous features: Under what circumstances a continuous feature can be discretized to achieve better results. Q:CTR estimates, it is found that CTR estimates are generally used with LR, and the characteristics are discrete. Why must we use discrete features? The advantage of doing so is where. A: In industry, the continuous value is rarely used as the characteristic input of the logistic regression model, but the continuous featur

"The paper on the end of the light, do not know this matter to preach." The recent use of logical regression (LR) in the work of classification, using the Sklearn in the existing algorithm package. In this process encountered some problems, stimulated my interpretation of the Sklearn source code, which has a further understanding of the logic of regression, some of the pits left before also have a new understanding. The Bowen first from the linear reg
