About

With this program, you can randomly choose an existing problem in luogu. You can also customize your preferences.

How to use

Download the source code and run main.py. Enter your customizations in Python grammar. If no customization needed, simply enter True. Here are some variables you can use:

• difficulty: One-digit difficulty from 0(grey) to 7(black).
• accepted: An integer that indicates how many people accepted this problem.
• submit: An integer that shows how many submissions does the problem has.
• acrate: An integer from 0 to 100 that shows the AC rate of the problem in percentage. Specially, if there are no submissions, it is None.
• translation: A boolean indicating does the problem needs translations.
• tag: An array that contains all tags of the problem in integer.

For example, if you want to search for green problems that requires segment tree, search for:

difficulty==4 and 42 in tag

If the data is outdated, run download.py. It may need 6 or 7 hours to fetch the whole problemset. This program helps you to update the data by updating the database. You can modify them by hand if you want. The database contains:

• accepted.txt for variable accepted
• acrate.txt for variable acrate
• difficulty.txt for variable difficulty
• submit.txt for variable submit
• tag.txt for array tag
• translation.txt for variable translation

They are all in value-key format. For example, the first line of submit.txt is:

990434 P1000

This indicates that P1000 has 990434 submissions.
