Answers and Thoughts on "pirate money"

Many friends have been paying attention to the issue of "pirate money" a few days ago. Maybe you already have the correct answer, maybe you are still thinking. In any case, under the "assumption" of the question, the answer can always be obtained, but after the answer, do you think of it?

The standard answer is: pirate 1 is assigned 1 gold coin to pirate 3, and pirate 4 or 5 is assigned 2 gold coins. The allocation scheme can be written as (, 0, 0) or (, 2 ).

The reasoning process is like this: From the back to the back, if the first-to-second pirates feed the sharks, and only the fourth and fifth are left, the first five will vote against the four to feed the sharks, to swallow all gold coins. Therefore, on the 4th, only support on the 3rd can save your life. If you know this on the 3rd, you will propose a (, 0, 0) allocation scheme. If you have no more than 4 or 5, you will classify all the gold coins as existing ones, because he knows that he got nothing on the 4th, but he will still vote in favor, and add himself to his plan to pass. However, if we get to the No. 3 solution on the No. 2, we will propose the (, 0,) solution, that is, we will give up the No. 3 solution and give each gold coin to the No. 4 and No. 5. Because the scheme is more advantageous for No. 4 and No. 5 than in the allocation of No. 3, they will support him instead of wanting him to go out and be allocated by No. 3. In this way, 98 gold coins will be taken away on the 2nd. However, the No. 2 solution will be understood by No. 1. The No. 1 solution will be proposed (97,) or (, 2, give up on the 2nd, give a gold coin on the 3th, and give two gold coins on the 4th (or 5th. Because the scheme of No. 1 is better for No. 3 and No. 4 (or No. 5) than that of No. 2, they will vote in favor of No. 1, in addition to the ticket for the first account, the plan for the first account can be approved, and 97 gold coins can easily fall into the bag. This is undoubtedly the solution for getting the maximum benefit on the first day!

Thoughts:

1. It is not easy to be a boss. Entrepreneurs Should "flatten" all aspects ". The entrepreneurs mentioned here include the politicians said by Kumamoto.

2. The key for any "Allocator" to pass his or her own plan is to first consider what the "Challenger" Allocation Plan is and get the maximum benefit at the minimum cost, draw on the least satisfied people in the "Challenger" allocation scheme. Think about the peasant uprising of history dynasties, think about the constant battle of the court, think about the alliance and betrayal that are everywhere in our time, think about the inner fight of an enterprise, and think about the politics at the foot of the Office, which winner is not using a method similar to "pirate money?

Why are revolutionaries always looking for poor people, because they are the most frustrated people. Why is there no market in Saudi Arabia for terrorists? It is very popular in Afghanistan because Afghanistan is a global abandon. Why are the top leaders in an enterprise often put aside No. 2 in internal control, but they are very popular with accounting and cashiers? Isn't it because the company's little people are very good at buying, the second character is always ambitious to replace it ......

3. first-mover advantage and backward disadvantage in international transactions. 1 seems to be the most likely to feed sharks, but he firmly grasped the First Advantage, The result not only eliminated the threat of death, but also the biggest benefit. Isn't this the first advantage of advanced countries in the process of globalization? On the 5th, it seems the safest, no threat of death, and even the benefits of fishermen. However, you can only get a small cup of cake because you have to look at other people's faces. Isn't this a portrayal of the latencies? It is expected that if the Chinese are always in the No. 5 position and are always waiting for others to set rules, they will not be better in the future than the No. 5!

4. The logic of piracy is certainly not the only inside story of the real world. The pirate gold score model is a very sophisticated model, but it is only a useful intellectual test, and the real world is much more complicated than this model.

5. In reality, no one is absolutely smart and "absolutely rational ". Back to the "pirate fund" model, as long as one of the three, four, or five deviates from an absolutely smart and extremely rational assumption, no. 1 will be thrown into the sea. Therefore, the first thing to consider on the first day of the first day is that the intelligence and rationality of his pirate brothers are unreliable, and they are not afraid to take 97 gold coins, fight their lives to go crazy.

6. Preference, utility, and substitution are another major issues. In reality, people are so complicated that a person's nerves may deviate a little from each other, so they may be indifferent to the gold coins and may like to watch their associates be thrown into the sea to feed sharks. If this is the case, the scheme that was successfully achieved on the first day has become a self-digging grave!

7. What's more, the old saying is "touching your ears ". This translation into an economic language is information asymmetry. Due to information asymmetry, lies and false promises are useful, and conspiracy will grow like weeds and benefit from opportunities. For example, on the 2nd, a smoke bullet can be played on the 3rd, 4th, and 5th. It is assumed that he will add a gold coin to any allocation scheme proposed on the 1st. What is the result?

8. Generally, in the real world, everyone has a fair standard of self-recognition, so they often say, "who has moved my cheese "? Moreover, rules are formulated by people. Therefore, when people realize that this rule is not good for themselves and know that it is not good for most people, they will think of modifying the rule. That is to say, "Culture can subvert the system ". It can be expected that once the solution proposed on the first day does not match what everyone thinks, there will be a lot of noise ...... When everyone gets up, can I go out with 97 gold coins on the first day without loss? The biggest possible reason is that the pirates will request to modify the rules and then re-allocate them.

9. What if I change from a game to a repeated game? For example, when you get another 100 gold coins, you should first score them by pirate 2 ...... And then the third ...... This is a bit like the US presidential election. To put it bluntly, it is actually the sharing system under the democratic system. It may be even worse. For example, four people may think: On the first day, they will have 97 gold coins. As a result, they immediately formed an anti-1st grand League and formulated a new rule: four people evenly divided the gold coins and threw the first to the sea ...... This is a Q-style revolutionary ideal: holding the banner of egalitarianism, throwing the rich into the abyss of death, sleeping in the bed of Wu ma ......

10. The importance of a system is most prominent in this story. Such a distribution system can easily induce people to kill each other, which is easily overlooked in the game. An important rule in the US presidential system is that after the president leaves office, a library can be built (of course there are other generous conditions), rather than being pushed to the sea ", this guarantees the exchange of power among civilizations. As you can imagine, if all the Presidents do not end well, the President will not only refuse to step down, but will also do a lot to protect his hands and feet, politics cannot be clear.

11. The reality is indeed too complicated. This also shows how important the system is and how important it is to participate in the formulation of the system.

There are many other things that can't be completely explained, so we can leave them to everyone to think about in the future.
