. This is why humans love flowers. This is also the root cause of making flowers a messenger of love. In fact, not only is the beauty of flowers because of the sexual needs of humans (specifically, it should be the needs of reproduction), including the evaluation of beauty. Women with big breasts and big buttocks are considered to be better able to give birth and nurture future generations. So it was later called beauty. That is, the intention of a beauty is to be good at raising future generati

Ancient naive theory People in the ancient age were over years old. Why?Because they adapt to the laws of natural changes in the world, understand the number of skills, have a certain degree of diet restraint, work and rest have a certain degree of Convention, do not over labor. People who understand the principles of health care in the old age often teach people what?In such a case, we should avoid the attacks against the attackers and thieves in a

Bzoj4724 -- number theory, bzoj Number Theory Question:B In number, each number I (I =,..., B-1) has a [I. You need to use these numbers to form the largest number X in B (cannot have leading zero, do not need to use all numbers), so that X is a multiple of the B-1. Q: What is the k-bit number of X in the B-base system? The second digit is 0th bits ). Ideas: Due to the following theorem: A * Bk rating a (m

largest of the common factors of A and B is the largest common factor of a and B, or greatest common divisor, which is recorded as GCD (A, b), sometimes précis-writers (A, B)Definition 1.5: Set A and B are two non-0 certificates, the minimum positive common multiple of a and B are least common multiple of A and B, recorded as LCM (A, b), sometimes précis-writers to [A, b]Basic Operation Properties. . . . .About the operations of GCD and LCM. . The above two figures are the legendary Euclidean t

associated with the front and back is called a multi-stage decision-making process. • Decision Tree and dynamic planning are the main methods to solve multi-stage decision-making problems. Decision Trees are composed of nodes and branches, each line from the root of a tree to the top of a tree represents a decision-making scheme and a possible situation. • Decision-making analysis should be calculated from the treasure to the root of the tree. This method for decision analysis from the back to

Paradigm Theory, database Paradigm Theory Currently, relational databases have six paradigms: 1NF, 2NF, 3NF, 4nf, and 5NF ), the sixth paradigm (6NF ). The paradigm that meets the minimum requirements is the first paradigm. The second paradigm that meets more requirements on the basis of the first paradigm is called the second paradigm, and the rest of the paradigms are in turn. Generally, databases can mee

Historical Theory of Spring (Data desensitization) and Historical Theory of spring Desensitization At present, the architecture of many companies has been migrated from Struts2 to SpringMVC. Have you ever wondered why SpringMVC is used instead of Servlet + JSP to build a Java web project? In this case, let's start with the source. The source of Struts2 is actually Servlet. Servlet is used to receive request

There are a lot of gamification issues, and you can almost guide the production of the game. I didn't give a clear idea about how to apply it to business. I have made several examples by others. The translation of several important concepts in the book is not suitable. One is points, which is generally translated as points. It is a bit awkward to translate into points in the book; the translation of badges into badges is not as good as Sina Weibo's "Medal. Game-based thinking: Changing the new

Entropy of information theoryIf the discrete random variable has a P (X) distribution, then X carries the entropy (amount of information):The reason for using log2 as a base is to make it easy to measure how many bits the information can be represented by. Because 1 bit is not 0 or 1. It can be deduced from the above formula that when the probability of K states is the same, the greater the entropy of the random variable x carries. As indicated by the Bernoulli distribution the entropy carries t

I. The theory of NP completeness (1) in the Turing computer model, the move function δ is a single value , that is, for each value in the Q´TK, when it belongs to the domain of δ definition Q´ (t´{l,r,s}) k There is only one value corresponding to it, the Turing is called deterministic Turing, denoted is DTM(deterministic Turing Machine). (2) non-deterministic Turing ( Ndtm ): A K-band non-deterministic Turing-Force M is a 7-tuple: (Q,T,I,Δ,B,Q0,QF)

column of the table above. The following explanation is very interesting: While at first glance this distinction between the two opposites may sound like a play on words, Herzberg argued that there are two distinct human needs portrayed. first, there are physiological needs that can be fulfilled by money, for example, to purchase food and shelter. second, there is the psychological need to achieve and grow, and this need is fulfilled by activities that cause one to grow. Some practical signific

Objective In this paper, some basic concepts and theorem proofs of group theory are mainly used in the contest of informatics, and if there are improper places,In this paper, the Burnside lemma and the Polya theorem are only introduced and proved to achieve a preliminary understanding of the purpose, without in-depth discussion, specific topics and implementation methods will be mentioned in the future blog definition If from a formulaic standpoint,

I do not know if you have read CA's "Long Tail theory" this book. A book that was very hot a few years ago. In Chen Nian began to involve Web site optimization and data analysis, and accumulated a certain website operation and data statistics, again take out the "long tail theory" read through it, found that many problems are suddenly enlightened. According to some of the current understanding of the book t

Hello everyone, I am the Phantom of the Rain. In front of you to share a lot about SEO knowledge, there are several is about SEO learning, but many people for learning SEO or have their own set of methods, may be introduced before the method for everyone is not feasible suggestions, Today, I would like to tell you that I have a little bit of SEO ideas: seo learning to first theory before the actual combat, do not forget the deep level of improvement.

Color is one of the most important parts of your site. However, color is often just a matter of hindsight after a comprehensive decision, sometimes even ignoring it. That's not going to work. Color helps users interpret information. How does the color of this picture feel? Do these fireworks feel festive? The photo is from Expressmonorail. Color is one of the most important parts of your site. However, color is often just a matter of hindsight after a comprehensive decision, sometimes even

(Spring's idea: not reinventing the wheel), but spring is the epitome of all of these open source frameworks, providing an ideal platform for integrating a wide range of open source results. So Rod Johnson's contribution to the Java EE seems to me to be higher than anyone else's. -Excerpt from a netizen's comment In a word, in the field of technology, he is a great man, he is our hero in mind! (Hehe, "hero" this honorific call up a bit disgusting, if do not do Java friend to see I casually cal

In his famous book "Big Design", Hawking proposes a theory of the so-called dependency model: a physical or World picture is a model (usually mathematical) and a set of rules that link model elements to observations. In such a realism, Hawking proposes a good model of the four criteria, namely 1 it is graceful; 2 does not contain arbitrary, adjustable elements; 3 in accordance with and able to interpret all existing observations; 4 can predict the fut

Note : This is a task spanning several years, and the title can also be called "learning statistics from the To Do list." When I was distressed by P-values a few years ago, I didn't know what Python was, and then, after touching Python, I liked the language. Statistics as the basis of data science, want to do this work, this is always a way around the sill.In fact, from the middle school began to study statistics, the earliest write "positive" character recount (equivalent to find the majority),
