2021 MCM Question A: Fungi
Figure 1 : The relationship between the mycelial elongation (mm/day) of various fungi and the wood decomposition rate (% of mass loss in 122 days) at various temperatures . ( Figure 1C in [1] )
There is no data to study the changes of a single fungus, the competitive environment of multiple fungi, and the influence of different environments on fungi. There is no data. It is difficult to choose data to build a model by yourself.
2021MCM Question B : Fighting wildfires
Australia's 2019-2020 fire season has caused devastating wildfires in every state, with the greatest impact on New South Wales and eastern Victoria. Wildfires occur during severe droughts and persistent heat waves, which are exacerbated by climate change. Figure 1 shows the wildfire hotspots in this regard, from October 1, 2019 to January 7, 2020, from October 1st yellow indicates the first fire to January 6, and red indicates active fire on January 7 In 2020, firefighters have used drones for surveillance and situational awareness ( SSA) for several years.
I feel that this is a GIS topic, and it is more difficult to use geographic information visualization plus spatial analysis related knowledge.
2021 MCM Question C: Confirm the buzz about the Hornets
Image recognition is very interesting. I think it involves simple operations such as image graying, image noise reduction, image filtering, and feature extraction. I feel that the amount of data is large, and Matlab is suitable for image batch processing, which is not as difficult as imagined.
2021 ICM Question D: The Influence of Music
Your team has been determined by the Integrated Music ( ICM) Association to establish a model for measuring musical influence. This question asks you to check the evolution and revolutionary trends of artists and genres. To this end, ICM provides some data sets for your team:
Personally think this question is difficult. On the one hand, the question has a large amount of data and involves many levels. In particular, some data is still character data, which is not convenient to process. Secondly, it may also involve algorithms such as networks, graph theory, and trees, which are not suitable for Matlab.
Problem E: Re-optimizing the food system
Question F: Check the pulse and temperature of higher education
Putting these two questions together, I think the two questions are more similar, and they test the ability of partial liberal arts. The key to the problem is to determine indicators, and then data-driven. Finally, the data can be processed.
