(turn) Regional game winning strategy, pre-game meditation!

1. The evaluation of the game will be slow, and occasionally encounter more than 10 minutes to return the results of the situation,This period of time can not wait for the results, must start other questions,If WA, two questions are done at the same time.each question must be printed first.
2. The meal at the game is not for you to eat at that time, it is for you to eat after the game. Basically, the first few teams in the game are not eaten unless they lead a lot.
3. Many players, especially the first time to participate in the competition, to a new environment, all when the tour, visit the visit, find classmates to find classmates, play Lele put the matter behind the head, the results of the game naturally no good results, such examples too much. Soafter the entry to the place to always remember that they are to play, good rest, preparation.
4.The day before the competition to sleep more than 10 hours, it helps to keep the energy in the game, and most of the time it's boring for players to play for 3 hours. The day before dinner and breakfast to eat good, the reason ibid, to know that the next meal will be 3 o'clock in the afternoon after the game to eat.
5. To the new environment, always pay attention to stay away from disease, cold enteritis disease is not small, but is the natural enemy of the results.
6. English is not good, can not understand, to check the dictionary, lazy once less a problem, away from the medal.
7. Can be nervous, eliminate panic, panic is the enemy of the question, any time, if you find yourself or teammatesa panic situation reminds you to take a deep breath.
8. Do not make mistakes when tapping code and sample data, pay special attention to text information.
9. The first simple question to the team of the most stable people do, in case of trouble, do not panic, if there are many teams are out of the more need not worry, it must be a simple problem, it must be quickly made out,A few minutes later is better than 20 minutes.。 Also take care not to PE.
10. The last hour is the height of the quiz, who loosens and who lags behind. The last hour is normal, two better.
Each of these articles has a source, each containing the lessons of the past, each of which may waste your efforts for a year, not to belittle.
some of the following articles come from other schools, some of which are summarized:
11. Whether or not a person passes,all the questions have to be read, preferably two or more per question ., as far as possible to eliminate the problem. To fully understand the test instructions, the right to judge the difficulty of the problem,Don't take it for granted.
12. Although the discussion contributed to the question, but in the past the first place in each division is basically fighting each other, but mutual understanding, feel that a problem suitable for other people to do is changed hands.
13. Keep your mind flexible and think about astray when normal methods are not working, such as special data structures that are not common, plus preprocessing, time-limited searches, etc. Efficiency is the first, if you feel DP trouble with memory search, in shortconsider clearly after the shortest time to make a question.
14. The competition needs to be more stable than usual, check out the key place after the procedure, try to 1Y. For WA's problem, do not change a place on the hand, it is likely that the wrong place, to be stable, to understand under pressure to be careful. The test for WA is complete and must be measured at every point, but not necessarily particularly complex.to take into account the various boundary conditions of the test,For example, the matrix may be 1*1 or 1*n or m*1.
15. Unless a large number of people are made,finally consider the complex geometry problem, the accuracy caused too many problems. Double type operation should be careful to determine the size, absolute value and so on. Generally do not use the float type.
16. Block copy be careful to check that the appropriate section has been modified correctly.
17. Write the program on paper to be as complete as possible,do not exceed one hour per question on machine time (including input, test, and commissioning). Program error if the moment can not be ruled out should be printed out to read and put the machine out.
18. Pay attention to the question number when submitting, do not stagger the question. This situation occurs because of the pc^2 interface.
19. Try to think of the math that the topic can use.
20. Initialization is essential.
21. Array row subscript do not reverse, bit operation or string which is 0 and n do not reverse.
22. Remember to turn off all debugging information when you submit.
23. It is really a necessity to substitute for a problem.
24. After thinking, write the program before you think about time and space efficiency. There will be no more than 30 seconds in the competition (except in the foreign division), 10 seconds and above generally not more than 3 lanes.
25. The competition opportunity is only once a year, training for a long time, if there is an omission in the game, then the next year will be regretted. For those who are not ready to compete next year, they should cherish the last chance of entry.

Attached to the previous written "Team game description"

1 to have to do more of the players, for various types of questions are involved, do a stable, generally the first two simple questions can be guaranteed fast, and more than 99% an AC.
2 Some people have to deal with math and geometry problems, but complex geometric problems to be put in the final, some of the commonly used functions to have template preparation. such as precision control, cross product, convex hull and so on.
3 to be able to deal with problems, and to ensure a certain pass rate, most of the games have at least one such problem, such as POJ 1913,toj 1092.
4 to someone to be very familiar with DP, single, double, relative and so on. For classic DP extremely easy.
5 Some of the strange algorithms have been a program, extensive, for number theory, some special conclusions in graph theory are known. such as TOJ 1584,zoj 1015,uva 10733.
6 Some people to the complex general algorithm to do the program, such as network flow of the minimum cost of the maximum flow and so on a series of flows, the cutting point/cutting edge, heuristic search/beat and so on.
7 template to write their own, and the other two people have read carefully, using the previous topics for many tests. The template should be full, but to control the length, because many of the division has begun to limit the number of pages.
8 to someone familiar with the Linux VI/GCC system, familiar with pc^2, must pay attention to the formal competition do not appear to submit the wrong problem. Also try Dev-c++ and other free software under Windows. In short, familiar with the game environment.
9 Every practice game should be as a formal game to do, to ensure that all the questions have been seen, after the game to the non-finished problems as far as possible to fill up.
10 if possible, take a look at the summaries, photos and videos of previous competitions, shorten the distance from the official competitions, and avoid the tense of the formal competitions.
The best case scenario is that three players can do all kinds of topics, but each has its own focus.
To ensure that a problem can be done by someone, dare to do, at least to know the practice.
