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.
And with a single generator we hope to generate a variety of tests. In this problem, for example, the test cases should have different lengths, the array elements should have different value ranges, and the answer for the tests should be controllable (having a specific amount of YES and NO answers).
Recently someone asked for a tutorial about using polygon to prepare problems, I couldn't find such tutorial so I decided to write one. You can find the tutorial here. This tutorial is beginner friendly, I tried to explain every step in details and through the tutorial I have created a complete simple problem. I hope you will find this tutorial ...
27 wrz 2020 · You can add tests to validate them and check if your validator handles every possible case correctly, let’s add some tests using Add test. For every test you add you should add it’s verdict \(1\) or VALID if this test is valid, and \(0\) or INVALID otherwise.
*has extra registration. → Streams Atcoder ABC #362 Solution Discussion
A guide for creating Codeforces problems on Polygon. The problem creator generates test case inputs using a test case script, generator, and (optional) validator. When a contest participant submits his or her solution, a checker can be used to verify if their program's output has valid syntax.
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
