Rating, tags and complexity missing in problem_list.csv

[igabirondo16]

Hello everyone,

I downloaded the dataset this week, and the metadata that appears in problem_list.csv is incomplete, as the columns rating, tags and complexity are empty. My file problem_list.csv looks like this:

id,name,dataset,time_limit,memory_limit,rating,tags,complexity
p00000,QQ,AIZU,1000,131072,,,
p00001,List of Top 3 Hills,AIZU,1000,131072,,,
p00002,Digit Number,AIZU,1000,131072,,,
...

Does anyone know how can I get these values? They would be very useful for my research.

Thanks beforehand,
Iñigo.
