Dear participants of CEOI 2018, contestants, team leaders and guests!
It is my pleasure to welcome you all in Warsaw in Poland for the 25th Central European Olympiad in Informatics. I am glad to see participants from all the member countries of CEOI: Croatia, Czechia, Germany, Hungary, Poland, Romania, Slovakia and Slovenia, as well as from all the guest countries: Austria, Azerbaijan, Georgia, Italy and Switzerland.
I do hope that CEOI 2018 will be a great experience for all of you. I hope that you will enjoy tackling the problems that were prepared for you by our jury. I hope that our guides will be able to show you around Warsaw and will help create an enjoyable atmosphere of the competition. Finally, I hope that you will be able to talk with other participants and start long lasting friendships and, possibly, future scientific collaborations.
Good luck to all of you!
Dr. Jakub Radoszewski
Chair of CEOI 2018
