Entertaining Children

   Chapter 1248 Memory Test

   Yan Ke and others are all MIT students, living in the school dormitory, and are not looking for another place to live. Although it is summer vacation and there are many vacancies in the dormitory, the beds in the American university dormitories are still relatively private. When friends who are not popular come to the dormitory, Xiao Yao will naturally not squeeze the dorm with them.

  Cambridge is a well-known university city, with all kinds of basic supporting facilities complete, there are many hotels in the city, and the environment is quite good. Xiao Yao had booked the hotel in advance before coming.

   Xiao Yao has been on the plane for more than 20 hours. He will meet with the people from the card counting team tomorrow. Naturally, there will be no shows in the evening. After Yan Ke and others sent Xiao Yao to the hotel for check-in, they invited Xiao Yao to eat a meal, asked him to rest, and left.

  The next morning, Yan Ke and the three came to the hotel to pick up Xiao Yao, and went to the MIT campus to meet with other people in the card counting team.

  The card counting group is not a student club recognized by the school at MIT. It can only be regarded as an unofficial secret organization at best. However, MIT has very rich hardware resources, and it is very easy for students to find a few classrooms as activities. Xiao Yao and Yan Ke met the members of the card counting group in a relatively remote classroom on the MIT campus.

  There are a total of seven members in this card counting group. In addition to the three of Yan Ke, there are also four members. When Yan Ke and Xiao Yao arrived, the four members were already waiting in the classroom. After the meeting, Yan Ke introduced Xiao Yao and the four to each other.

  The gender of these four people is three men and one woman. Judging by their skin color, the three boys are a Caucasian white, a South American Latino, and an Indian. The girl looks like an East Asian and European Latino white.

   Xiao Yao came to the card counting group to learn the card counting method is actually a kind of "peach picking" behavior. In order to persuade the other four to agree to Xiao Yao's "pick the peaches", Yan Ke and the three would naturally introduce Xiao Yao's situation to the four in advance. However, Xiao Yao came to learn card counting, not to hold a fan meeting. When Yan Ke and the three introduced Xiao Yao, the focus was on Xiao Yao’s mathematical skills and their relationship with them, not on Xiao Yao’s identity. .

   Yan Ke said that Xiao Yao was a roommate they met when they participated in the training of the China Olympic National Team in middle school. Those who are able to enter the China National Olympic Mathematics Team's training camp are naturally not bad in mathematics. When Yan Ke joined the card counting group, they already had certain research results. The reason why they started to study the mathematical models and methods of card counting very early came from Xiao Yao’s proposal, so they brought them into the card counting group. Xiao Yao also contributed to the team’s results, and they had also agreed to go to the casino together to experience playing blackjack with card counting.

  The card counting team agreed that Xiao Yao came to learn card counting, mainly based on these two reasons. Yan Ke and the three didn't think Xiao Yao's celebrity status helped this matter, and they didn't even mention it to the four in the card counting group.

  In this meeting, when introducing the two sides to each other, the three of Yan Ke also did not deliberately mention Xiao Yao’s star status.

  However, Xiao Yao is also well-known in the United States. The fact that Yan Ke didn't mention it did not mean that the other four would not recognize Xiao Yao.

After greeting each other, the mixed-race girl stared at Xiao Yao for a while, and then suddenly asked: "Xiao Yao? Is your English name Yang? Are you a member of the "Immortals" band? The one who participated in the Eva Show and Quan The Chinese star of the celebrity celebrity?"

   "It's me!" Xiao Yao smiled and nodded, "But I have quit "Immortals" and am not a member of the band now."

   "Dean and the others haven't issued a statement that I have quit the band?" Xiao Yao said in his heart.

  Recently, this time has been relatively busy, and Xiao Yao did not pay attention to the news in this regard. However, for this kind of thing, Xiao Yao and Dean and the others can show their attitude. Even if they have not made a statement, Xiao Yao will not urge them. It was just a whisper in my heart at this time.

   "Oh, my God!" The girl named Sandra said to Yan Ke and others, "Why didn't you tell me that your friend is a big star in China?"

  "Does it matter?" Yan Ke said with a smile, "We let him learn card counting because he can learn in a short time and can do a good job. It doesn't matter whether he is a star!"

   "That's right!" said the white boy named Taylor in the card counting group. "Our card counting group taught him to count cards. It doesn't matter whether he is a star!"

   "Young, can you ask which school and major you are in?" Taylor turned to Xiao Yao and asked.

   "Ty, why are you asking this?" Sandra asked Tyler, "Do you want to show the superiority of your MIT students?"

   "Of course not." Taylor said to Sandra, "I'm just a little worried about his ability in mathematics."

  "Yan told us that Yang had participated in the training and selection of the China National Olympic Mathematics Team, and got a perfect score in math in the China SAT test!" Sandra said, "Do you think they are lying to us?"

"No, I believe in Yan!" Taylor said, "However, maybe Yang was a math genius like Yan in middle school, but the genius also needs to be learned. Members of the "Immortals" band can go to the Eva Show and the Masters. The performance shows that he is an entertainer and star, and I don’t think how long a well-known entertainment star can spend studying and researching mathematics. He is a well-known star in the United States. His playing team is not a hobby, but a career!"

   "It seems reasonable!" Sandra thought for a while and nodded gently.

  "Can you answer my question?" Taylor saw that Sandra had stopped speaking, and turned to ask Xiao Yao again.

"First of all correct, my profession is not just a band member, I am also a professional actor and director." Xiao Yao smiled, "Answer your question again. My undergraduate degree is at the Shencheng Theatre Academy in China. A professional film and television school, my major is Acting Department! I am currently a dual-degree master's degree in Director and Acting Department of Huaxia Yanjing Film Academy. From the name, it is still a professional film and television school. It is still related to film and television."

   "Do you need to learn mathematics in China's film and television academies and the film and television major you are studying?" Taylor asked again.

   "No need!" Xiao Yao shook his head, "My undergraduate and master's majors are art, and there are no mathematics-related courses!"

   "Ah~" Xiao Yao said so, and the four non-China members of the card counting group all showed surprise and disappointment.

   "Thank you for your frankness!" Taylor nodded to Xiao Yao, "but sorry..."

   "Wait!" Yan Ke interrupted aloud when he knew what Taylor wanted to say.

  "Yan~" Taylor looked at Yan Ke with some dissatisfaction.

  Taylor will certainly be dissatisfied with Yan Ke. However, compared with Yan Ke's interruption, he was even more dissatisfied with the fact that when Yan Ke and the three introduced Xiao Yao's situation to them, they didn't mention Xiao Yao's current situation at all and concealed the four of them.

The four of them heard that the three of Yan Ke said that Xiao Yao had participated in the China Olympic Mathematical National Team training together with them. The Chinese SAT mathematics scored a perfect score, and the total score is the first person in the city, so they took Xiao Yao for granted. He is a mathematics genius and continues to develop in the direction of science and engineering like these mathematics geniuses. Even if they didn't come to MIT like them, most of them were studying at Shuimu University in China or other famous schools in other countries. I didn't expect this person to learn art and didn't learn mathematics at all in four or five years.

"Taylor," Yan Ke ignored the dissatisfaction in Taylor's eyes and said with a smile, "Now our card counting model has been made. Yang is here to learn card counting, not to help us study how to do card counting. We don't need to tell. What mathematical principles did he use to count cards, as long as he remembered those calculation formulas and told him how to count and how to do it. So even if Yang did not learn advanced mathematics knowledge in college, he could still learn card counting. "

   "But," Taylor said.

"I know!" Yan Ke interrupted Taylor with another wave of his hand. "What is the basis of card counting? The first one requires a strong memory and the ability to remember used cards. The second one is a strong mental arithmetic ability. , Calculate the probability of the next card size through the formula, and make the most favorable choice from the probability. Memory and mental arithmetic ability, for reasons of talent, can also be improved through acquired training. We are both talented, The day after tomorrow he did a lot of exercise. Even if Yang did less exercise the day after tomorrow, but if his talent is high enough, he will not be worse than us!"

   "What did you say? Talent?" Taylor said.

"Yes," Yan Ke said with a smile, "We all consider ourselves to be geniuses and mathematics geniuses, but Yang is our even more talented genius! We know that Yang was in the high school China Olympic Mathematics training team. At that time, Yang was younger than us. , But he is stronger than the three of us in memory and mental arithmetic, and is much stronger. Even though Yang hasn’t studied mathematics or trained in these years, he is very talented in these two areas. We believe in his two abilities. It's still better than us now!"

   "Is it possible?" Taylor said in disbelief.

"Is that right? We will know after a test?" Yan Ke said, "We had previously said that we would train and evaluate Yang. Now that Yang has come to the United States from China, we can't do nothing. Just let him go back?"

   "What do you think?" Taylor turned his head and asked the other three non-China members.

  Yan Ke, the three Chinese people have always advanced and retreated together. Looking at the expressions of Chen Jiwei and Yu Gang, it is obvious that they all have the same idea. Taylor felt that there was no need to ask, so he only asked the other three non-Huaxia members.

   "I think I should let Young try!" Sandra said first.

   "We are already here anyway, and we have no plans today," the South American Latino named Sam took out a deck of playing cards from his pocket and shrugged, "It's okay to play!"

  The Indian boy named Raj looked more introverted, did not speak, just nodded.

   "Okay!" Seeing everyone's agreement, Taylor nodded, "Sam, let's test it, first test his ability to record cards!"

   "OK!" Sam nodded, put the two desks together, stood on one side of the desk, pointed to the other side and said to Xiao Yao, "Please sit down!"

   Xiao Yao smiled, moved a chair and sat in the middle of the two desks that were put together. The other people in the group naturally all stood by the table and watched.

"I have a deck of playing cards in my hand now," Sam said to Xiao Yao as he opened the cards in his hand, "I will shuffle the cards first, break up all the playing cards in order, and then issue the cards at the casino's blackjack table. The cards are dealt at the speed of the card. We calculate according to four players plus a dealer, not counting the cards, each time ten cards are dealt, and then deducted, you must tell all the ten cards, and then play the first In the second round, there are still ten cards. After the deal, you can add them. You can play five rounds with fifty-two cards. As long as you can get all of them right, the test is over."

  "Are all the necessary suits and points correct?" Xiao Yao asked.

  "It's best!" Sam thought for a while, and said, "But if you can't remember the suit, you can remember how many times a certain point appears!"

"Wait!" Yu Gang said this time, "This is too difficult! We have a way to count cards, let alone remember suits, don't even need to remember the points so clearly! We treat certain points as Put a code name together..."

"Stop!" Xiao Yao said to Gang, "I haven't passed the test, so don't tell me your card counting method! There are five or six decks of cards in the casino, and in many cases there are more than four players at the table. Now Sam has only tested me with one deck of cards according to the situation of four players, which can be considered a lower standard. I am willing to accept this level of challenge!"

   "OK!" Sam took out the king and the king and threw it away, shuffled the remaining cards, and then began to deal the cards.

  Sam's cards are dealt according to the blackjack rule. First, four cards were sent in front of Xiao Yao, then one in front of him, and then one in each of the five positions. Except for the first card in front of him, which was buckled, all the other cards were revealed directly. After the ten cards were all dealt out, Sam first revealed the card he was holding in front of him, and showed it to Xiao Yao separately, made a gesture, and then buckled all the ten cards one by one.

  "Taylor, put the cards away and check them!" Sam pointed to the ten buckled cards on the table and said to Taylor.

  Taylor understood what Sam meant, and reached for the cards on the table.

   "Wait!" Xiao Yao grabbed Taylor's hand reaching for the poker cards on the table.

   "What's wrong?" Sam and Taylor both looked at Xiao Yao curiously.

   "I want to increase the difficulty a little bit!" Xiao Yao smiled, "I not only keep track of the cards, but also remember their positions."

  "Here!" Xiao Yao reached out and clicked on the two buckled cards on his leftmost side, "Three diamonds and ten spades!"

  Taylor reached out and picked up the two cards on the far left of Xiao Yao and looked at it, then nodded.

"Here, club six and heart ace, here, spades nine and heart eight..." Xiao Yao clicked in turn, and finally pointed to the two cards in front of Sam. "Finally, Sam is in front of you, two jacks, respectively. Spades and hearts!"

  Sam picked up the two cards in front of him and looked at it, then nodded.

  All guesses were correct in the first round, but the people in the card counting group did not show any expressions of surprise. After all, it's only ten cards, and they can do it all. Even if Xiao Yao increased the difficulty of suit and position, it was not impossible for them. The key is to see if Xiao Yao can remember so clearly after the cards behind him are too many.

Putting the two cards in his hand in front of him, Sam looked at Xiao Yao and said: "Originally, I planned to put all the used cards away, and then in the next few rounds, I would randomly ask you if a certain point has already appeared. The number of times. Since you want to increase the difficulty yourself, I will not accept these cards. Later, I will not only ask questions about the number of times a certain point appears, but also about the pile of cards that have been used in a certain position. Maybe I will ask about the pile of cards. Is there a certain point and suit in the card, and it may also ask you to tell all the points and suits of all the cards in that pile. Can you do it?"

   Sam’s doing this is to further upgrade the difficulty of the test, and to follow the requirements of card counting. However, after Xiao Yao took the initiative to upgrade the difficulty for the first time, Yan Ke and others no longer wanted to help Xiao Yao speak up. They all entered the theater mode.

   "I don't know, but I am willing to give it a try!" Sure enough, Xiao Yao didn't refuse, and smiled and nodded.
