"Okay, how are you going to test me?" Seeing the innocent and cute appearance of the little girl, Roland couldn't help but feel childlike. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"I'll give you a debut problem, and if you can solve it, you'll be really smart."

Roland became interested and said with a smile: "Then try it." ”

"Listen, the title is this: Once upon a time there were five pirates, and their names didn't matter, so they called them One, Two, Three, Four, and Five, and one day they fished out of the wreck and opened the jar, and found that it contained gold coins, and they took out a total of 100 gold coins from the jar, and when they took out the last gold coin, a puff of black smoke came out of the jar, and they became a terrible devil!"

"Very interesting story, and then what?" Roland took the "Lion Princess" by the hand and sat down in the restaurant.

Lyudmila sat on the other side of the little girl, listening curiously to her subject.

Beowulf and Natasha sat across the table, smiling at Roland and their daughter, as if they were looking forward to this test of wisdom.

"The devil is very powerful, and as soon as he comes out, he uses a spell to defeat all the pirates, and he says that he will kill them." Bella continued, "The pirates were frightened and knelt down and begged the devil for mercy. The devil said he could give them a chance to live, but they had to distribute the gold according to the rules they had proposed. ”

"What rules?" Lyudmila asked curiously.

"The devil requires all pirates to come up with a distribution plan that is most beneficial to them, starting with pirate number one and submitting their plans in order, and finally pirate number five, as long as the distribution plan is approved by half or more of his peers, it can be determined, if he can't get half of his peers, then the devil will kill the person who proposed the plan, replace it with another proposal, and so on, until pirate five."

Listening to Bella's words, Lyudmila frowned: "The rules of this game are not fair, and they are the most beneficial to Pirate Five, he is the last proposer, and he will not be killed by the devil no matter what...... But is the devil's word credible? ”

Bella smiled, her eyes flashing with a sly brilliance: "It's not wrong that the devil is bad, but he won't break the rules he set, and now the question is, if you are Pirate One, what kind of distribution plan do you have to come up with to ensure that you survive and get the most gold?" ”

"Divide it evenly, right? I think that's the fairest thing for everyone. Lyudmila said without thinking.

Bella shrugged her shoulders and spread her hands: "You got the crux of the matter wrong, no one cares about whether the public is unfair or not, what they care about is to take advantage of more, do you really think that equal distribution is in your best interest?" ”

Lyudmila was speechless, her mind a little messy.

Roland took a sip of tea and said to Bella with a smile, "If I were Pirate One, I would give myself 97 gold coins." ”

"How is this possible!" Lyudmila looked at him in surprise, "You took 97 gold coins yourself, and the other four can only share 3 gold coins?" Unless they are all insane, it is impossible to agree to such a distribution scheme! Bella, isn't that so? ”

The little face of the "lion princess" was wrinkled, and she looked very struck, and squeezed out a bitter smile to Lyudmila: "Sister Mira...... You are wrong, Brother Roland's distribution scheme is the most correct. ”

Lyudmila patted her forehead and almost groaned: "Wait...... My mind is a mess, you give me some time to brush up my thoughts. ”

Bella didn't feel sorry for her, turned to Roland and said, "I read this question of 'pirate money' from an ancient book, and I pondered it with my parents for several days to find the best solution, and then I asked this question to many so-called smart people, including the officials of the town hall, wealthy merchants, and distinguished visitors, most of whom could not answer the question, and so far only two people have given the correct answer except you. ”

"Which two?" Roland asked.

"The first is Victoria's secretary, Miss Katya, who accompanied Victoria to the castle for afternoon tea that day, and I asked them this question, and Victoria had no clue at all, and quickly gave up, and Katya kept thinking about it, and in the evening she finally came up with the right plan."

"The second is a mage named Shabarin, yesterday afternoon my father invited him to come to the castle to talk about things, I heard that the mage is always very clever, and took the opportunity to go to the study to deliver refreshments to ask him this question, Sabalin said that he needed some time to think, and later when he took his leave, he gave the correct answer."

The little girl looked at Roland with suspicion: "Miss Katya and Master Sabalin are the smartest people I have ever met, but they also have to think for a long time to come up with an answer, how can you be right all of a sudden, is it a blind guess?" ”

Roland did not answer Bella's question, but instead asked Beowulf: "How did Shabalin talk to you?" ”

Beowulf shook his head, his brows twisted into the word "Chuan", "We communicated well, but unfortunately we couldn't reach a consensus in the end, Shabahin insisted on getting at least half of his salary before returning to work, and if his demands could not be met within three days, he would lead all the construction workers to demonstrate." ”

"How much does it cost?"

"200,000 gold coins is the minimum, Natasha and I are anxious about this matter, thanks to your operation plan, we can see the dawn of solving the problem." Beowulf smiled and raised his glass to him.

Roland clinked his glass with him, took a sip of dry and hot vodka, and muttered: "If only 200,000 can appease Shabah and his union, it would be the best, the pre-sale package can make up this amount, the problem is Sergei...... If Shabalin is swayed by him, it will not be solved by 200,000. ”

"I'm worried about that, too, so I'm going to have to try to save some more emergency funds."

"Hey! I'm talking to you, why are you ignoring me? Bella felt that she was being left out, and pulled Roland's sleeve and didn't let go, pouting her little mouth.

Roland put down his wine glass, touched the little girl's fluffy blonde hair, and told her with a smile: "Of course I am not guessing, but I came up with that plan through rigorous reasoning." ”

"Then tell me how you reasoned?" Bella said unconvinced.

Lyudmila also cast an expectant gaze, she thought for a long time, but still didn't figure it out.

Roland glanced at the table, then arranged five spice bottles in a row, representing the five pirates, and then pulled three gold coins out of his pocket to act as props.

"It takes some reverse thinking to solve this problem, and if we work backwards from back to front, we can see that the problem is actually not difficult to solve."

Roland picked up a spice bottle, "Assuming this is Pirate 5, his advantage is that he is the last to propose a distribution plan, that is, he will only have a chance to propose if all the plans proposed by the previous four people are rejected and killed by the devil." In this way, he is undoubtedly the safest, and if he is the only one left in the end, there will be no objection to monopolizing all the gold coins, so his best strategy is to oppose all the proposals and let the first four companions die! ”

"It makes sense, and then what?" Bella put her hands on her cheeks, expecting him to continue reasoning.

Roland picked up another spice bottle, "Assuming this is Pirate No. 4, he knows well what No. 5 is thinking, and knows that no matter what kind of proposal he puts forward, he will be opposed by No. 5 and will inevitably die-even if he gives 100 gold coins to No. 5, God knows if the other party will cross the river and tear down the bridge?" ”

"So what should he do?" Lyudmila couldn't help but worry about the fate of Pirate 4.

"If No. 4 wants to live, the only strategy is to agree with No. 3's proposal, so that it will not be his turn to propose, and he will not be vetoed by No. 5," Roland smiled slightly and picked up the third spice bottle, "Now we are from the position of No. 3 to consider, since no matter how the gold is distributed, No. 4 can get support, and getting No. 4's support is only half, that means that no matter what plan he proposes, he can pass the test, so what do you think he should do?" ”

"Keep all the gold to yourself, of course." Lyudmila replied.

Roland nodded, "That's right, owning 100 gold coins alone is the best strategy for No. 3, but there is a premise for this, that is, No. 2 has been killed by the devil, otherwise it would not be his turn to propose this plan." ”

He picked up the penultimate spice bottle, "Now we are thinking from the position of No. 2, No. 2 knows that No. 3 has sinister intentions and will definitely oppose his proposal, so if he wants to live, he can only enlist the support of No. 4 and No. 5, and according to No. 3's plan, No. 4 and No. 5 will get nothing, so he only needs to give No. 4 and No. 5 one gold coin each, and he can buy them to support him, and the remaining 98 gold coins will be his exclusive use, which is his best strategy." ”

Picking up the penultimate spice bottle, Roland smiled in his eyes: "Finally, let's consider No. 1's proposal, in fact, his direct competitor is No. 2, and No. 2 will definitely oppose him if he wants to maximize his interests, so he can give up fighting for No. 2, and win two allies from the remaining three to ensure that his proposal passes." If No. 2's proposal succeeds, No. 3 will get nothing, so in No. 1's opinion, No. 3 is the easiest to buy, and it is enough to give him a gold coin, while No. 4 and No. 5 may get a gold coin from No. 2, so the price code to buy them is higher, at least two gold coins are needed, fortunately, No. 1 has been supported by No. 3, No. 4 and No. 5 He only needs to buy one of the two to get half of the support, and the rest can not give a penny, so his best strategy is to give No. 4 or No. 5 two gold coins, and No. 3 one gold coin, Exclusive possession of 97 gold coins. ”

"Wow! Vigraf was right, you're smart! Bella applauded him excitedly.

Lyudmila pondered for a while before she figured out Roland's reasoning process, and said with a wry smile: "I'd better be a fool with peace of mind, thinking like this all day long, my brain is going to smoke." (To be continued.) )
