Hey. In this post I want to offer you some tasks on convex hull trick.
There are some useful posts about CHT below.

Taks which can be solved by using CHT with stack
1083E - Орехус и прямоугольники
Other tasks you can solve by using Li Chao Tree or dynamic CHT
Why do you think that these problems are useful if you didn't upsolve them?
Hmm.. Why if this blog about CHT 3 of 5 tasks uses data structer called "Li Chao tree"? I know that this is variation of on-line CHT but I think that this is the topic of another blog.
Thank you VEGAnn. It will be fixed.
