AtCoder Grand Contest 031 will be held on Saturday (time). There are unusually many writers: yutaka1999, yosupo, DEGwer, maroonrk, hogloid, HIR180. All of them are participating in Oman camp now, and they formed a problemset together.
This is the first GP30-rated contest in this season — see this post for details.
