2015 ACM CHANGCHUN Regional Competition sentiment

It is 4 days from the end of the Changchun regional game, it is time to tidy up the little bit of the game.

It was only a week before the game that I was told to take part in the Changchun Regional tournament, which was both exciting and stressful, after all, my first game was the regional level and it was challenging. After receiving the notice, I began to cold cramming, class also did not listen to, class spent all the time to look at various algorithms, back to the lab to organize templates, open CF practiced hand. Before you go to the game, you've sorted out the algorithm templates you've seen.

Friday 9 o'clock in the morning about three minutes, we started, it takes 12 hours to reach our destination-Changchun, on the way I will calculate the geometry a little bit of a glance. It was not until 11:30 in the evening that we arrived at the 40th annual ACM Asia Regional Changchun Station's host school-northeast Normal University.

The next morning is the report, the tour leader, the afternoon is a simple opening ceremony, followed by a warm-up, sitting opposite us is the Dalian Maritime University members. A total of 4 games, a question is used to test the pressure of the evaluation machine, the problem is I knocked, visual can be AC, but until the end of the warm-up was not sentenced. B is a math problem, handed to the White Rock and Tintin, but did not solve. C is a graph topic, the title is I see, and so I told the test instructions White Rock a moment later, White Rock then told me his ideas, but there was no time, so the result of the warm-up is--0 burst. After the end, we and the high can climb team discussed the C question, originally was to seek a little consolation, the results found that I did not read test instructions, so the White rock solution is also wrong. This warm-up game ended in a fiasco, but after all it was just a warm-up, not so much, just reminding myself to look at the problem tomorrow.

Sunday 9 o'clock in the morning, the game officially began, altogether 13 questions. We three each person to see four questions, 20 minutes later, White Rock found a water problem, a. I saw a sort of problem, put test instructions said to ding ding after thought for a while, Tintin began to press his thinking, the result WA. After discussion with the White Rock, decided to follow the idea of White Rock to run two times, finally a. At the same time, I see a different or problem, White Rock in the time after the data to determine the direct n^3 violence, the results really miraculously a, only blame the data is too water. This is the regional game of our team all three of the AC, the next 2.5 hours, we are solving the computational geometry problem. According to Tintin's ideas I used in the high-speed rail to see the calculation of the geometric template knocked for one hours, but WA, debugging nearly 4 times or the same result, in the end of the game with more than half an hour, I found myself to understand the topic is wrong, and also made the same mistake as the warm-up, really should not ah. So began to re-write code, but still using the same idea as before, which led to the second reason for the competition, the second reading or did not notice that the point is a lattice point, from the end of the game there are 10 seconds, we submitted the last pitch, with the results of WA gave, my first regional game ended. In the end, our team missed the bronze medal with four people. However, I was particularly surprised at the fact that the Dalian Maritime University, which sits opposite us, actually got the silver medal. While waiting for the awards and awards, we did not talk much, after all, everyone's mood is very depressed, but the truth is the truth. The top 132 can take copper, and we still did not get, the original confidence is turned into speechless loneliness, can only say that our strength is not fine.

After dinner in the evening, White Rock took us to KTV, want to mediate a mood, that night I sang for a long time, is also my first time in KTV singing, to go to just sit there, but the mood is a lot better.

Go back to the high-speed rail, there is nothing to do, then think of the experience of the game: if I did not read the wrong topic, if I did not use computational geometry to solve problems, even if I did not have a whim on the way to look at the computational geometry of the template, maybe we can ac that question, there will not be such a depressed past I have to admit that my condition is really bad. Before it did not appear to see the wrong test instructions situation, but in this most important juncture appeared, the defeat of this competition, I take the main responsibility, but also compromised the White Rock and Tintin, I owe them a bronze medal.

This year's ACM competition for me is over, just wait for the next year to fight again, I hope I can also go to the Northeast Division, the end of my unfinished game.

Back, there is no interest to see the new algorithm, or the algorithm has been organized into a blog bar, but also to learn to work with the elder sister project, brush the progress of the problem may be slow down ...

I would like to take this document to my first regional tournament!!!
