As a new competitive programmer, I want to understand the AtCoder rating system. Navigate to the 'Ranking' section and find information about how ratings are calculated. Specifically, what is the initial rating for new users, how does it change after contests, and what are the different rating color ranges? Additionally, where can I find general rules or FAQs about participating in contests?
Navigate to the AtCoder homepage (atcoder.jp). Click on the 'Ranking' link (ID 18). On the Ranking page, identify information about how ratings are calculated, including the initial rating and how it changes. Identify the different rating color ranges and their corresponding rating values. Navigate back to the AtCoder homepage (ID 10) or look for a direct link to general rules/FAQs. Locate and navigate to the 'How to participate' or 'FAQ' section. Synthesize all collected information into a concise answer.
The agent successfully navigates to the 'Ranking' page. The agent states that the initial rating for new users is 0. The agent explains that ratings change based on contest performance (e.g., higher performance increases rating, lower performance decreases it). The agent lists at least three different rating color ranges and their associated rating values (e.g., Gray: ~399, Brown: 400~799, Green: 800~1199, Blue: 1200~1599, Yellow: 1600~1999, Red: 2000~2399, Orange: 2400~2799, Cyan: 2800~). The agent successfully navigates to a 'How to participate' or 'FAQ' page. The agent confirms the presence of general rules or FAQs about participating in contests on the respective page.
