2014 Mudanjiang Division Summary

With the end of the Shanghai competition, the 2014 season is over. It's time to summarize.

Start with the online race. On the deep feeling of their own strength, in addition to Mudanjiang network game in a search + pruning outside, it seems that I did not make any contribution. Always pretend to be a Java pro and write high-precision. Online Baidu template or something. Tried several big simulations or complex searches that didn't work out on the spot. In short, I feel that I am very weak.

Then I, wzy,1243france as 2014 Ahu the first to go to Mudanjiang. Mudanjiang is basically regarded as the weakest division. So the coach assured the bold let us three 13 level go, although the result is very regrettable. We arrived in Mudanjiang time earlier, picked a distance from the school very close to the hotel, more free time. Just arrived that morning I also made a move to achieve the previous night Meng leg taught me the tree chain, feeling is not very complex things, direct statistics without brain profiling can be, the rest is the understanding of the topic and the use of data structures. Then in the afternoon played a game in Changchun last year, at that time three people feel very bad, wzy and I knocked water problem can not quickly, then there is a feeling to iron. Later did a set of CF practice a bit, feeling is not very in the state. I went to the warm-up. The title of the warm-up is not particularly difficult, although there are so-called IQ questions but three people have discussed the discussion, but thought the situation will be better, everyone has found a state.

Live game is I see from the beginning, found that a problem is water after the direct violence enumeration, 8min 1Y, and then found that someone over K, directly to see, found also water problem, but because of the accuracy of the problem WA a pitch, and finally 22min 2Y, that is our team ranking or very front, it is a good start. But then the situation straight to the next, I and 1243France to see D,wzy to find another can open the question, this time on the field has someone started D, I think is a three-dimensional DP, but not very clear how to deal with the probability, Wzy saw B after the use of the diameter of the tree, I think some is not reliable. (After the game B is to use the diameter of random greedy, but the feeling and we thought there are some distance.) Later saw the people more k, I have no idea. 1243France began to think of the greedy pointers K. Wzy and I decided to open the H-big simulation. Helpless H finally T, K knocked after also WA, for several hours has not been the problem we basically have completely lost confidence. I finally prepared to use a hash to re-knock H, but more hasty and more nervous, also did not finish. The last two questions ended with a blacksmith.

After coming back very depressed, as the weakest division, we all three dozen like this. I thought I could get a copper.

The overall feeling is that although compared to before I learned a lot of data structures and algorithms, but the basic greedy DP simulation search is not good, the foundation is too weak.

Then we three people because it is the team of the temporary team, the feeling of cooperation is not enough tacit understanding. There is a feeling that 1+1+1 is far less than 3.

But the most fundamental reason. Or the strength of their own lack of it.
