Zheng erba learned algorithms for almost two months. Although algorithm and data structure were required by computer science students, they only stayed at the "Understanding" level, it is quite superficial. More importantly, it can be used in a different way. Therefore, the so-called "zhen'er Ba Jing" learning algorithm, that is, the process of understanding the essence of the algorithm IDEA, the process of summarizing and abstracting the thinking methodology, the process of generalization of various problem-solving skills, and the memory hiding through continuous exercises. process ..

Before learning algorithms, I spent more than half a year studying psychology and Cognitive Neuroscience in my spare time. So the first thing I did before I started seriously thinking about algorithm problems was to think carefully about the problems that have been confusing me-how did those seemingly insensible inspirations come from.

One of the greatest principles of modern psychology is that all psychological activities are physiological activities at the same time. -- In fact, "psychological activity" is just a popular term for "brain nerve activity. Although the structure of the brain is extremely complex, what many people do not know is that modern neuroscience's understanding of the function of the brain is already quite complete in principle, but for memory and learning, this is even more because Eric Kandel's breakthrough work has become quite clear. It can be said that the remaining work is mainly to supplement the details. Therefore, with the help of three books on memory and learning, a book devoted to solving psychology, Wikipedia and polia's three-volume problem-solving books, as well as the reflection and summary of the thinking process in the process of thinking on a limited number of issues, I tried to give a thought and a summary of the psychology of solving problems ("solving problems with polia"). -- This sounds strange. How can a person who only has a preliminary algorithm think about the thought process that covers all problems? Let's refer to the famous inventor paradox of polia: Sometimes a general problem is better solved than a special case.

However, when I think about general problems clearly and clearly understand the nature of problem-solving thinking, it does not mean that I am omnipotent, And I am immediately good at solving all algorithm problems. It's not just about thinking. In fact, one of the key points summarized in "solving problems with polia" is that the heuristic method is valuable, but the importance of knowledge is irreplaceable. There is no universal and omnipotent knowledge, or we don't have to explore the laws of the material world today. In addition, the process of acquiring knowledge --Learning-in essence, it is a physical activity (although there is a certain method of physical activity)This physical activity is roughly divided into two steps:

• Convert external (books) knowledgeExplicit Memory.
• Translate explicit memoryInner memory.

(For more information about what explicit memory is and what implicit memory is, see Wikipedia or polia.)

The second step involves two processes:

• The knowledge about the way of thinking is transformed into inner and hidden memory, so that we can follow it without knowing it.
• The clues about fact knowledge (such as "Theorem" and "nature") are converted into inner and hidden memories, so that xx can think of YY. (Refer 《Find the lost selfChapter 2 "memory construction: Coding and extraction of the present and the past ")

I have a good book, "Art of learning", on the first point.

There is a good example for the second point, which was first read from the blog of Teacher Li xiaolai ("Treat time as a friend"):

I seldom forget the books I read. Why? Good method. What method? The heart is hot. Cut down all scissors and cut down the books. I need this page. I need it. I have classified it. What should I do on the back? Print it out, or buy two books at the beginning, cut them apart, and cut them apart. As a result, the book was also split up. This is my reading method.

So how to classify it? I have many clips made by myself. I write the clips and classify all the materials. After reading a book, all of them entered my clips. I can separate thousands of classes, which are very detailed. For example, according to the classification of libraries, such as philosophy and religion, religion is classified into Buddhism, Taoism, and Catholic religion. I am more refined by Li min, and the Catholic Church can also be divided. The priest is considered a class. The priest can also be subdivided. The priest is gay, and the priest is also vulgar. Female is a type of homosexuality, while female is also vulgar.

Any content in the book is included in my documents. What should I do? When I want to write a novel, I need this information. I just need to write it. Or something happened, which is related to the sex of the nun. I want to post my thoughts on the news, take the news, open the information, and merge the two to write the article immediately.

In other words, after reading this book, I dumped eight pieces and split them apart. But I caught it up. I don't remember the information. I tried to stick it together with my patience and put it in the clip. I only need to remember these titles. The title is classified according to my habits. It is basically translated into English, and is arranged in the mother-in-law. Sometimes there are some Chinese characters.

Today, I want to tell you the skills of seeing a house. Li has learned so much about it, and he has a good memory. I tell you that memory can be trained. In the beginning, you should not be lazy. Do not lie there and read a book. It is still neat and neat after reading this book. This is wrong. After reading this book, the book will be unloaded in eight parts, and the book will be written into a folder.

Today, I am very happy to tell you how to read books. Do not read this book. I did not know that, because I saw it at the time, but it was a waste. You cannot systematically hold the information, which is linked to the information. However, if you look for this method, you can capture and buckle the essence of the books you have read. This is my academic method for steel-making.

It uses the most profound principle of memory.

Our brain is essentially a calculator, and its material base is a neural network. continuous practice is to train the connection strength between nodes in the network (the SYN connection strength between neural cells. -Unfortunately, the well-trained neural network parameters in Einstein's brain cannot be directly imported into my brain. Maybe they can be done in the future, but there is only a stupid way at present, it's really depressing.

So, pick up the book and train your neural network ..

Reference

I listed two bean columns on Douban.

1. The books of psychology and neuroscience (preliminary) that have been read for more than half a year are listed in this column.
2. The books related to the thinking methodology are listed in this column.
3. If you think there are too many books listed in it and you don't know where to start, you can give priority to the books listed in question solving with polia.

P.s.

We haven't publicized our toplanguage discussion group for a long time. This lovely discussion group has been around for more than half a year. Over the past half year, it has seen more than people, more than 8 thousand discussions, and more than 6 hundred topics. Currently, the activity level is second only to Python-CN, and more importantly, the overall discussion quality in the discussion group is quite high (just a while before and after the Chinese New Year ). I have benefited a lot. Thank you!

So why are we making publicity again? Gain has recently discovered a large number of cattle and tigers in it, so I would like to brag about it for you without saying anything, "welcome to join the toplanguage brotherhood": P weNoTo discuss the problem, you can ask Google for help, or you can check the questions found in the book.
