It got delayed for 2 years because of Covid.

It got delayed for another half a year for war.

Now there's a flooding in Dubai which is getting flights cancelled left and right (including ours), even getting some teams stuck there.

So this World Finals is cursed.

Ok but honest opinion

Hi everyone! I have been inspired by xiaowuc1 recent event to write this blog post. This list is very comprehensive, even though I do not keep detailed logs of problems I have written.

There are a few things you will notice after reading through these problems. In no particular order:

  1. All of these problems are "high-quality" — all of them have appeared on a CF round! This is not due to my skill in generating "high-quality" problems, but because I have set only one problem. You'll see that all of my problems are generated from observing real-life events and then constructing problems out of those scenarios. There are many ideas that have been proposed and thrown into the void because they were worse (rejected!). I think the only problem in this list is ok, but I am particularly proud of it!
  2. The difficulties on these problems generally lean 1900, and the problems almost always lean standard. I know for sure about the difficulty because there is only one problem, and that's what the CF problem rating tells. The problem itself is a standard technique, but it may be a good exercise for those slightly below that rating. So do try it!
  3. I like to embed random references into my problems. For my only problem, the reference is a puzzle game, which the problem is exactly the 1D version of that!
  4. As far as I remember, none of the problems I wrote have appeared in very similar forms before. Any such problems I am aware of are labeled as such. Please include more examples in the comments.
  5. I want to author more problems. But I'm not very good at making problems X(

This table was generated manually so I could write this blog post right after waking up (it's 6AM here right now). Again, I look forward to waking up to a lot of criticism.
