3xian retired post------The guardian of the ACM spiritual World

--------------------------------------------------------------------------------------------------------------- ------------------------------------------------------------------
The last day, the sky fluttering snowflakes, pretending to send me away.

This time the WF battle is not so smooth, the early C topic took about 1 seconds to conceive, however, because the output format more than a space until 2.5 hours to escape wrong answer entanglement. Fortunately Lynncui during Dudangyimian D. The final result is not good, but no regrets, never regret.

By contrast, teams from all over the world have made me see a lot of power, and every question has been taken, including SJTU's deceptive submission H has been killed. I am proud to be a man of the Earth.

WF Trip is very luxurious (sample:1300 one night Hotel, 991 breakfast), a lot of activities, service is good. But the end of the hit it off is that you are friends, as to why hit it off I also do not understand. According to the master HH, that's what the ACM brings to us. Also grateful to the HH Master as the University coach, but for us to take more than the game moment.

I was planning to take this year as a retired war because I believe that it is not appropriate to completely dissipate a college career in a competition. But this experience let me particularly reluctant to all the road friends, if there is a chance still want to pull everyone to drink some wine, talk about the day. Although retired, I will still find interesting topics to do, will still devote a lot of time in the algorithm, but no longer care about the game thing.

The last day, my mind is full of the two years of ACM career fragments. In fact, I have long wanted to write down the complicated emotions in ACM career, but I can be afraid to make things too clear that it will ruin some friendships. Now, if criticism is not straightforward, then praise is meaningless.

Fledgling

When I first entered the university gate, I had not heard of ACM. Most of the class in the valet, like a freshman contact with C language, but high school time on the ASP and flash as more familiar. Freshman was Fyj teacher fancy, into a graduate-oriented project team, and did not give me what task, only let me learn things, in fact, did not learn anything, but inside a senior to me to pick up some reverse telecommuting, I am a person package to do ASP Mall, forum and so on, to complete an approximate spend three weeks, remuneration 1000+. After earning some money, he skipped a large class and bought a plane ticket to live in front of his girlfriend in Xiamen. I think it's a little weird in retrospect. At that time, it was really smart, usually do a variety of things like to do, the class also people worship me for the teacher to learn the guitar.

At the end of last semester, when he was drinking with 4h, he first mentioned ACM (in fact he was referring to OJ), and I immediately said it was a very interesting thing, fair and challenging. Go back that night to run to Hdoj try, the following is a virgin sex.
2007-12-04 20:19:32 wrong Answer 10000MS 0K 419087 B C 3xian


Ps:hdoj A+b is really a toss-up, for people who do not understand OJ model, where to know what to do with EOF.

The next few days quickly made up the maximum substring and the high-precision addition of something. Originally wanted to do according to the number sequence, it is easy to imagine, alive by 1007 Card dead (two-dimensional recently Euclid Point pair). At that time the large trumpet was handed over more than 200 times, and finally the water supply past-sort it in two directions, then compare the adjacent points. In other words, even if the water used to be difficult, an unknown algorithm why the Aborigines, to think of the classic division and sweep the surface line method is not likely to do things, let alone linear sieve method. And this topic gives me the biggest inspiration is: Originally C language has qsort this kind of thing.

Later looking for 4h singled out several times, randomly draw the question number, than who AC faster, trembling to win the victory.

Team

In the second semester, I took a peek at the ACM team in a public trash can, yes, it was the trash, and I pulled it out of the trash. necessary, go to interview with 4h. Asked, hanging over the branch did not. I said I hung up on history and stuff. (In fact, but also hung a high number, but "such" is a sea of hundred Chuan's word of speech ... So it doesn't count as cheating. A year later the leader found me hanging too high, a face want to kick me out of the team's appearance. Then, I was tested to the time complexity of the queue, 4h answer Nlogn. I said, I have been in Hangzhou Electric has done 100 questions, enough not. Yue, the time to see your school game performance.

Later, the school race took the 3rd place, the top two of the three are still confused who. In fact, there is a big string in the school game and, I did not read test instructions, otherwise it is expected to win the championship? Anyway it was a smooth team, and was thrown directly to the provincial race as the death squads. At that time, I told the leader that such a sentence makes him feel very bored, I said, next year I must be the most fierce in our school.

In addition, the team's most favored is the 06-level WJS, I quietly with 4h said, next year, this time, the 06 most fierce is not wjs, but CCF.

Ziliang

Had to mention this man. Ziliang is the originator of the modern history of the Guang Gong ACM, the first and first silver of the regional races won by Guang Gong in 07. All the way to give us direction, although the details of not too much, in fact, there is no need to guide too much. In my opinion, his thinking ability is higher than the current group of people A grade, is estimated to belong to the type of loneliness.
From the start of my team, Ziliang started to fool everyone. For example, at the beginning of pretending to come out of our sister-in-the-minute, she (he) asked me if I had to do Oi, I answer: Oi? OJ ...
However, the influence of Ziliang also caused a bad influence. All the people in the team worshipped him and worshipped him every day with him blowing water in the Q Group. On average, it takes two or three hours or more to blow every day, which is not considered a disguised suicide. In the early days I tried to integrate into such an atmosphere, after all, isolation is difficult to survive. Later found to be very uncomfortable, the tradeoff after the choice of shielding Q Group. In fact, this phenomenon in the team is ultimately unrelated to Ziliang, not that he does not know what he is doing, but that the players do not know what they are doing.

Weekly race

After entering the team, we were organized to participate in the weekly competition, it is from this time, just into the team I have lost a sense of belonging to the whole team. Originally, according to the strength of my team, it should be no problem to get rid of the second title, but in fact sometimes I do not guarantee the position of the champion. Yes, there are too many people who cheat on the internet for code. Do not want to roll name and no need to name, boys are rampant, girls are very rampant. At that time I saw a lot of sad phenomena, such as some people who did not cheat because of being sadistic and lose confidence and fade out of ACM, such as some people themselves cheat after the private still told me who cheat, such as the teacher does not care about what happened here. Generally speaking, Guang gong was such a dish of the ACM team, we incredibly also dug through the pit of their own people to meet that point of poor vanity, really the mother of iniquity.

When I first participated in the weekly race, I was extremely nervous, so invested so much that I was later disappointed. After all the weeks, I saw the familiar accounts on ranklist and I didn't want to touch the keyboard. Last fall I received a summary of the training to see a lot of people say that I always "Mars like Disappearing", this simple reason, no one realized.

Nonetheless, there are some funny memories in midweek, such as Lynncui dare to randomly play the table, such as WJS with a non-backtracking DFS water over the shortest, such as YQJ attempt to use a long double over a variety of high precision, such as my freshman game "invented" the prim, Disjoint Set, for example, when I brush my teeth with sesame seeds, I found that my mom and dad made a variety of energy-replenishing snacks during my weekly race.

Grow

From the beginning to the present, I am infatuated with the algorithm, and finally did not become a good acmer. This is contrary to Ziliang, who does not like to stand on the shoulders of giants, he knows the game is the most important tactics and skills. Must See, play ACM and play algorithm is different things, ACM is the test of wisdom, test comprehensive quality, I dare to say, ACM play well even do not need to deliberately learn what algorithm. Although we occasionally see some topics that require some mature classical algorithms, those topics are my favorite topics, but those topics belong to the most rubbish ACM topic. Another point of view, many people feel that the ACM out of the results of their own algorithm is good, this is a misconception, when you delve into any direction of the algorithm field, you will find that the ACM point is too small pediatrics, too not inflow. To put it bluntly, ACM is under the guise of algorithms to make everyone more than the brain.

Rough statistics, my second two years to do 1.6K, see Domestic and foreign paper 200 +, read a dozen books. It turns out to be the way it is. I'm not commenting on myself, what do you think it looks like?

For Acmer, Matrix67 already let the words, "usaco you honestly a word also don't look at the problem-solving report, done you will be invincible." We are everywhere to do a lot of many problems and the strength of the people do not go, such probably is the habit of looking at problem-solving reports, including the thought of not even want to rushed into the discuss inside to aim at.

Can't help but think of a person. In the fall of 08, the ACM Circle popped up a guy with a high-click blog, called ZfY. His appearance made many people see and had to express praise. Originally he is a good style of people, but to a certain extent let some people develop a new bad habits-do not question the paper, which is different from finding a problem-solving report, the name of the difference. Our school must also have some people think, delicacies is not brain is licked by donkey, do a essay use not to see so many papers. In fact, I basically do not touch the paper at the time of the problem, if the two mix together, the end result is basically this feeling not to the connotation of the paper, the head of the topic also White did.

In fact, in our environment to improve or relatively not easy, a few people around to provide help, and the way Daniel also do not like to talk to rookie. A lot of times you need to die, a person to die knock. Remember the first night to hit the V, the night to knock the dynamic tree, the new year to the next side open a few Wai Mahjong window little fart child shooting bamboo i dark translation suffix tree. As previously said these things are not related to ACM, but there is always a feeling in my heart, others oi the children of the things you can not write out can not be compared with others. Like the 08-year regional race of the online game that time, people have to kill the subject, we have not a person in the school has heard the name of the algorithm.

Later, the game experienced a lot, but also slowly gave themselves a position. Often on the internet to see a lot of people than the end of the game, and some people claim to have won the strength of gold, "did not play well." I used to have some time to run to do a lot of difficult problems, once thought oneself to the level of presenting illegal weapons, and later found that this is not the case at all. The real master is what kind of, they do not need to eat when the meditation, do not need to rely on the light of the bath when the flash, they are sitting there in the game can skillfully make a variety of problems, they can read the wrong questions to ensure that the results, in the wrong time to ensure that the results, when no one dared to submit the time, Cool coding at the end of the race. Simply put, they are not only the ability to do the problem, but also the comprehensive quality is strong. After the game said too much "originally", "If" the person, belongs to the psychological quality is not good, this is the comprehensive quality important piece, is also hinders the progress the piece. Therefore, when you do not achieve the desired goal, you should not think that you have lost a card, but should think about whether you really value that piece of cards.

Domestic and overseas

I have written this topic before, but I deleted it.

Domestic ACM circles always show a kind of impetuous atmosphere, although not lack of super-strong people, but the strongman are very low-key, or, the stronger school is behind closed doors. can go to see the domestic ACM the most Fire POJ forum, a dazzling array of things to beat: Beg/paste data, ask/paste code, call someone to check the wrong, the topic of the day, show off, the name of the two or three stream characters worship each other. Look at the letter in the station, how much is the code (my principle is to ask my thinking of a certain careful answer, the code is ignored). Then look at Baidu to the problem-solving report, how much is mutual plagiarism superficial understanding.

And abroad, I dare not say too perfect, after all, I do not know much about foreign countries. First of all, foreign OJ few of the above-beaten things. Since the focus of the topic of OJ abroad, with a number of foreign players to contact more and more, they send the mail will be very rigorous, almost every sentence will give proof, at least there will be a simple explanation, sometimes attached to a few papers. They never post code, but if you can't turn your brains around, people will ask if you need code. Especially in Spoj, I met Russian/Brazilian/Indian/American/Canadian friends and thanked them for all the ideas they brought me to inspire and to inspire people. Here is a small episode, there was a friend gave me two of the best Russian paper, the full text translated into Chinese after becoming a heavenly book, the full text translated into English is still a heavenly book, human flesh translated into Chinese or not to read, eventually human flesh translated into English and then repeated reading, eventually become ... The feat made the dorm call me a world class player.

I think that the domestic informatics competition results strong, and IT industry is not strong, from the ACM this piece to see clues. Our environment here is obviously inferior to that of man. I make an irresponsible assumption, assuming that all the world's classic schools are not allowed to participate in the ACM competition, the Chinese team is collectively abused. And the development of the industry can not rely only on the few people who have strong school.

Lynncui

It's time to talk about my teammates. The first thing to thank is the teammate Lynncui, who has always been very trusting of me, and I have been in the key timetable of the game to show a frizz side, here to express guilt. Because Lynncui is young, I am wonderfully witnessing the process of his two years of becoming a mature youth from a wool child people of nonsense. When we are still in the team, recruit the highest in the new group is him, I remember very clearly when he convinced that PE because the source code format is not correct ... So I directly put him as a dumb, million didn't think Lynncui in the future will become my best partner.

He belongs to the person who knows what he is doing, so he doesn't see the bad habit of discuss and problem-solving report. Although I sometimes think he is lazy, and did not spend too much energy in the ACM, but because of his sober and steadfast, as long as a little, can progress a little, as long as the mind, you can see the effect. I discussed the problem in our school, basically except Ziliang I have only looked for lynncui. He is able to keep a clear mind, both in practice and in the game, even though he is sometimes instilled with a new idea that feels as hard as stone. So our team has one of the most commonly used and most effective tactics: I have the idea of the lynncui head to fill ... After trying to get him to approve it was basically unmistakable, then he sat next to me and looked at me and wrote, one by one. Unfortunately for the latter half of the WF I was sitting on my own and failed to convince him of anything.

Of course, Lynncui's personal strength is not covered, his strength is to participate in various programming competitions as poor people to win clothes. Last gcj seemed to have more than 100 rows.

In any case, judging by his habits, it is certainly not bad money.

4h

This is my oldest partner and I have every ACM match with him. At the same time he is my drinking buddies and playmates, compared to ACM teammate this identity is a bit inferior. 4h the talent and knowledge background of the team is very high, but it seems not to take ACM as a matter of course. And how to say, do more quick, so that the late progress is not obvious. Once saw him after the data to the data can not be used to directly hit the table ac The wretched thing ... is very indignant. Anyway, he has been able to easily stay in team one, this is his ability, in a different perspective, is also the grief of the Guang Gong ACM team.

For me, 4h plays an important role in my college career. If it wasn't for him to drink with me and go to play with me at night, the area of Guang Gong was really not easy to stay.

Dieing

This is another person who trusts me very much, thank him. Guang gong inside, dieing to ACM's enthusiasm only renmin me, mingle in each big ACM God Group, worshipped each road God Ox. Dieing than we were 3 months late into training team, with Little Computer Foundation. This guy has a lot of bad habits, but he is so hard-working that he has today's results. We training team The most heard a word is dieing said: Delicacies despised. I always like to pick his bad habit, because I do not have the heart to see his enthusiasm in doing no work, but he seems to feel special grievance.

In a long period of time, Guang Gong only 4 of us continue to take the road of ACM (and 4 are also the same, this kind of dog excrement situation this year the regional game also two teams to win gold, mysterious incomparable), forget who gave us a nickname, Yue, four protectors. So dieing is always the most unfortunate, because a team is 3 people, and he is always ranked 4th, make his teammates are either old things, or children. And I think, is dieing did not break through their own, as long as he dared to stand up to the leader to say, I do not believe that I am 3 weaker than them! Then the number of PK after the elimination is not necessarily him.

Last year I was going to team up with dieing, after all, the 3+1 seems a bit more humane, but eventually the leader for the results or choose 3+1. Remember with dieing few team practice, as long as a question he said is the network flow ... Unexpectedly later dieing led to the Harbin regional race also really appeared the network flow, and one out is two, no suspense, immediately be we dieling children's shoes seconds kill, smooth win gold. It's amazing, but in any case, it's gratifying to be able to get good grades in the things I focus on, and to congratulate Dieing warmly.

Recruit New

Last year our ACM team recruit new, very funny, the main force are sophomore, recruit is a freshman. What is even more ridiculous is that I was commissioned to redesign the new flyers that I took from the trash cans in my freshman years. The design was exquisite, and the light background was printed out ... ), got a horse-racing face test to attract new students (pretending to test intelligence, actually brushing away those who copied the answers from the Internet).

As the propaganda was in place, more than 200 people came to the interview, but the leader took a foolish pattern-divided into 5 teams, scoring separately. I thought to myself, we don't have enough people to get started here for 5. And then there was something even more foolish. At that time asked to give everyone a few points, the full score is 10 points, and in addition to me and dieing this team, each team played 7 points/7.5 minutes/8 points, I was almost on the other 4 teams of people rough, this is a never-fail lottery or what, as a screening link, Good people should give 9 points 10 points, no one should be bold to low score, 0 points have no problem. Ultimately, most people are unable to differentiate and take a random progression.

The people who came in are now sophomores, and I haven't seen much of it. I have stressed to them many times, to the use of our BBS, we progress together to progress, still cold a piece. So far this batch of people have not discussed any algorithmic problems with me, just occasionally find me to help them to check the wrong code, to find me to mark the process.

Strike

Back

I don't have much to do with the ACM thing.
As far as I know, the probability of coming out of Egypt next year is very large, there are dream wings @uestc, small Hao hu @hdu, [email protected] (this is no suspense). Wish them to achieve their goals, Egypt is certainly more fun than the domestic.

At last

I still wonder what it would be like if I didn't pick up the new flyers in the trash.

To put it bluntly, ACM is under the guise of algorithms to make everyone more than the brain. -Algorithms and contests are really two different things.
We are everywhere to do a lot of many problems and the strength of the people do not go, such probably is the habit of looking at problem-solving reports, including the thought of not even want to rushed into the discuss inside to aim at. --I said in the DP lecture that I didn't think = no progress.
Then look at the problem of Baidu to solve the report, how much is mutual plagiarism superficial understanding-on-line various error problem-solving reports, have been commonplace, and even someone wrong problem, and then someone put the wrong problem made out, put out a problem solving report, and then a bunch of people turn + worship ...

Independent thinking. Whether it's a question, or a life.
Above.
