Python example sharing --- logic reasoning programming solves eight queens, python logic reasoning
It can match the pattern like Haskell and Prolog,
Create logic to push to rules, describe the question, and get the answer.

I took the gcttest immediately. I did some questions two days ago and checked out that I was very poor at the "logic". Therefore, this was the key.
Logic can be divided into "Logical Reasoning", "argument Reasoning", and "analytical reasoning" from simplicity to complexity ". This article briefly introduces "Logical Reasonin

Inference Definition
There is a correlation between true and false judgments. The true/false relationship between judgment and judgment is the basis for people's reasoning activities.
The so-called reasoning is a new judgment method based on some judgments.
Composition of Reasoning
Reasoning consists of the premise

Dongye often adds all kinds of knowledge points to his reasoning novels, so that you can enjoy his strict logical reasoning and get popular science. Two examples have been given above, such as the P/NP problem in "the dedication of the Suspect X", and the Monroe Effect in the predicate of the series "probe Galileo. Therefore, it is strongly recommended that science and technology student

Poor effort and reasoning: Use the C ++ program to solve "who raises fish"
In this issue, programmers mentioned the "Einstein's puzzle" and I noticed the question "who raises fish. The problem is as follows:
1. There are 5 houses in a street and 5 colors are sprayed2. People of different nationalities living in each room3. Each person drinks different drinks, cigarettes of different brands, and petsKnown:1. British people live in a red house2. Dogs in

This series does not discuss the usage or use of keywords, but speculate why such design and specifications are there. It is a brain training factory.
In reasoning, we can use a paradox technique, that is to say, if a hypothesis is true, the phenomena that happen in reality will not exist. If it is necessary that the phenomena in reality be reasonable, the assumption must be reset. This model is essentially a language-based

I,
Mr. P and Mr. Q both have sufficient reasoning capabilities. On this day, they were waiting for a reasoning interview.
They know that there are 16 cards in the drawer of the table:
Peach A, Q, 4
Taotao J, 8, 4, 2, 7, 3
Caohua K, Q, 5, 4, 6
Square A, 5
Professor John picked a card from the 16 cards and told Mr. P the points of the card.Tell Mr. Q.Professor John asked Mr. P and Mr. Q: Can you tell from th

I think that as a programmer, I have a good logical reasoning ability. But yesterday I did four tests in a book called "What You Think You think is what you think.
Now we have published four questions to test the Logic Thinking Ability of programmers.
1. Even numbers and vowels.
2. colored circles and squares
Iii. Cunning drinkers
4. surfing the Internet during working hours
Conclusion: If a belief is built on imperfect

probability:B kills C, and the problem degrades to AB dual A's first shot.50% x 0. 35/0. 65 ≈ 0.269.
The survival rate of C is also very simple:B did not kill C, C killed B, A did not kill C, C killed.50% × 70% ≈ 0.35
Wow, it seems that a's first round of waiving gave a and c A a greater survival rate and made a most promising surviving player!Therefore, if a's logical reasoning is good, he must choose to drop in the first round.
From this, we learne

Question: a set of {1. n}. Calculate a subset so that the number of elements is the maximum and there are no two elements X1 * k = x2. Then, find the maximum number of elements.
Train of Thought: reasoning,N at the beginningDelete the K times, which is {k, 2 K, 3 K, 4 K, 5 K, 6 K ...}, the excess K ^ 2 will be deleted, so the number of K ^ 2 will be added back.Then, only the multiples of K ^ 2 are

The most well-organized numeric reasoning questions are as follows: a general summary of the questions, such as the type of equality, equality, parity, parity, split, parity, and two groups ----------------
1. 232,364,412 8, 52416 ,()
A. 64832 B. 624382 C. 723654 D. 87544
Resolution: first, judge that the numbers in this series are relatively large, which is more than three digits. It is difficult to use the program, so you can consider splitting item

In this round, I just want to elaborate on one point. In reasoning, some things cannot be completely determined. When necessary, some random elements must be introduced, although only approximate solutions can be obtained, the time efficiency is indeed much higher than the definite solution. At present, this idea has become a new method to solve some NP-hard problems. Because there are many practical problems that do not need to be computed by definit

Mr. Zhang and Mr. Xiaoqiang are both students of Mr. Zhang. Their birthdate is m month N. Both of them know that Miss Zhang's birthdate is one of the following 10 groups. Mr. Zhang told James about M, I told Xiao Qiang the N value. What day is Miss Zhang's birthday?

See the Code of the Great God. Understand for a long time ... It's really a gap.Test instructions: Given m, p, a, B, then XI satisfies the two formula, and the maximum value of xp1 + xp2 +...+ xPM is obtained.1, -1/sqrt (a) 2, X1+X2+...+XM = B*sqrt (a);Note: P is even.Problem solving: Because P is even, the P-sqrt (a) and -1/sqrt (a) are positive and sqrt (a) > 1/sqrt (a). So greedy thought when try to take sqrt (a); When the sum of the XI is already taken and greater than B*SQRT (a), then fetch

; Woman's second sentence, "Age equals the house number next door", We analyze the 3-number multiplication of 36, and the results are as follows:After looking at the house number, the census clerk said, "I need some more information," which means I know and, but the solution is not the only case, so we can infer that the age of three children is equalto three, that is, 1-6-6 and 2-2-9, and then the woman said a sentence " My oldest child is upstairs sleeping ", from this sentence can be launched
