New type of USACO Bronze problem

Hi, I, like many, have been seeing a new type of category for USACO Bronze, and I have a few questions about it.

So, like Drought for Jan contest, these problems are not “traditional” problems and are placed in additional questions in USACO guide.

I am not really comfortable with the shift, and would like to ask what specific type of problems those are categorized in, so I can practice more on it.


I thought they were categorized in the “ad-hoc” problems section…
But I would categorize “Drought” as a greedy problem - looking at every ~3 cows and making two of them have the same level eventually gets you to the final solution
