AWTF22 day 2

AtCoder WTF22 onsite round wrapped up today with the second contest (problems, combined results, top 5 on the left, mirror results, analysis, day 1 livestream, day 2 livestream). Once again I have managed to solve only one problem in 5 hours, but at least this time it was worth more points, and it was more satisfying as I have actually gradually approached the correct solution instead of just pulling it out of thin air. Overall, I remained in the 15th place that I had after the first round, and this is also the place I have when ordered by rating. I guess everything went as expected after all :) Qualifying next time would require crawling back into the top 8, though, and that will be a big challenge (current standings).

The overall top 3 solved non-intersecting sets of problems today, and it worked out the best for jiangly who combined the first place on day 2 with the second place on day 1 to win the event. Huge congratulations to him, ksun48 and tourist!

In a search for external factors that prevented myself from doing better, I've noticed that advancing to the finals from the 2021 season was the most correlated with the final results: the 2021 finalists got places 1,2,3,4,6,7,8 and 14. Maybe the problems for the finals were mostly prepared at the same time as the problems for the AGCs from 2021, and therefore require similar solving approaches? Unfortunately I have advanced in all other years, but not in 2021, hence the poor performance ;) Well done peti1234 for bucking the trend and winning the 5th place!

Huge thanks to the AtCoder organizing team for the amazing event, and to the problemsetters and testers for the problems! I have also enjoyed the social part immensely, meeting some old friends and getting to know new ones. I hope to meet you all again at some other competition in the future!

Thanks for reading, and check back tomorrow for this week's summary where I will also choose some AWTF problems to highlight.
