It aims to introduce the Polygon platform to the new problem setters, and guide them through the basic steps on creating a new problem from scratch. In the post, I have explained the concepts and practices that a problem setter need to know in order to use Polygon to prepare problems.
Polygon.Codeforces Tutorial - A Guide to Problem Preparation [Part 1] 08 Mar 2022. This is the first part of my series on problem preparation for a programming contest. In this part, we are going to familiarize ourselves with Polygon -- a modern platform for this purpose in a professional way!
The mission of Polygon is to provide platform for creation of programming contest problems. Polygon supports the whole development cycle: problem statement writing. test data preparing (generators supported) model solutions (including correct and wittingly incorrect) judging. automatic validation.

Equivalently, all its interior angles are less than 180 degrees. Polygon is simple if its boundary doesn't cross itself. I will present two algorithms for each problem: one for arbitrary simple polygon, and one for strictly convex polygon, that has better complexity.

PDF-CodeForces-Problems. CodeForces problems in PDF files. The files in this repository extracted from CodeForces using codeforces2pdf, folders names represent the contests` IDs from CodeForces URLs, each folder contains the problems of the contest.
Polygon is a service to prepares programming problems and contests. It is usually used to prepare problems for olympiads/programming contests but it is also often used to prepare educational content. It is located at https://polygon.codeforces.com/ and is open to everybody. Here are three recent new features:
