Mathorcup ideas sharing in 2022

Today is the second day of the game , Through the statistics of your preliminary topics yesterday , The approximate statistical result is , The proportion of selected topics is 4:5:8:13. This result is based on your feedback and my own statistics. It should be different from the reality, but there is little difference . I think a more reasonable schedule should have selected the topic today and Friday , Look for ideas , Build the model , Saturday programming , Thesis writing , Sunday paper perfect . Such a schedule would be more reasonable , You can also adjust according to the actual situation of your team .

Based on the current number of topics , I think those who want to win a good award can try A、B, Those who want to protect the prize can consider C,D, Now I will make a brief comment on each topic . And attach a link to the specific ideas of each question . I hope that helps .

A topic Model and implementation of large-scale fingerprint image retrieval

A The question is the most difficult one in this competition . Through the title, we can see that this is a problem of image recognition . For this problem, you need to have high programming ability , And it has a certain foundation for algorithm optimization .A This difficulty is more suitable for players who want to win the first prize , It means that it is suitable for winning prizes , Not suitable for insurance . If you simply want that award , There is no choice here A,A It's very difficult and it's very likely that there will be no gain after a lot of effort , For high-level , Programming ability is good, you can try .

A The problem mainly uses image retrieval and image matching . I think it's not difficult for students of related majors , For non CV The overall difficulty of the students in this direction is relatively large . I'll share with you later A Code for , Ideas, etc .

B topic The problem of robot scheduling in unmanned warehouse

B On the whole, the problem is obviously an optimization model , For the three questions given , Set different constraints in turn . With the deepening of the problem, there are more and more constraints , The whole article needs to constantly improve the optimization model we initially established . be relative to A In terms of questions , It's simpler , But the overall difficulty is still very high . Topics for reference A topic .

In order to better help you understand B Establishment of problem optimization model , I have found the 2011 National Championship B The setting of traffic patrol platform ,03 year B Relevant papers and scoring rules for vehicle arrangement in open pit production, etc , I'll talk to you later 、 The code is packaged and sent to everyone . I hope it can help you .

C topic Automatic parking problem

C At present, we need to establish a reasonable parking model , Here we need to simulate , Difficulty relative A,B I think it's much smaller , The overall difficulty is moderate .

The first problem is numerical calculation , The solution of this problem should not require us to establish a model , Solve the problem directly according to the problem . Question two , We need to build a parking model , According to the path length required by the topic 、 toward 、 Speed 、 Establish a model based on acceleration and other data . Finally, the trajectory is optimized , To solve the . Question 3 . Based on problem 2, the parking model is established , Build an optimization model , Calculate the optimal parking space . At the same time, the model is extended , To apply to more situations .

Question 4 , The theoretical solution to our first three questions , Practice , Apply our model to the actual situation , From the current position Simulation results of driving trajectory to the optimal parking space .

C The problem involves a larger research direction, which is the parking problem , There is a lot of literature in this area , We will supplement the literature later 、 Improve the thinking code, etc .

D topic Location clustering and mobile communication network planning

D The question is the simplest one I think in this competition , This is also relative to this competition . The overall difficulty of this mom Cup , The depth has begun to keep up with the national competition .D Although the difficulty is the smallest of the four questions , But that doesn't mean he's simple . We can D The problem is solved as a data analysis problem .

The first problem is the optimization model , Plan the station site , To meet the requirements given in the title . Problem 2: add constraints , Consider the influence of sector angle . The third problem is regional clustering , Try to cluster all weak coverage points , Make the total time complexity of the clustering method as low as possible .

A,B,C,D The problem data has been updated .

What I can help you is still very limited , I hope these things are helpful to your topic selection . Detailed ideas , References will be added here later .

The remaining three days , You need to show your powers , The eight immortals crossed the sea .

May we meet at the summit ！！!
