Pisek ⌛

Tool for developing tasks for programming competitions. Currently used by:

• Kasiopea
• Czech Informatics Olympiad

And was used by:

• CEOI 2024

Install

Pisek requires Python ≥ 3.11. Install with pip:

pip install pisek

For upgrading add --upgrade:

pip install pisek --upgrade

Testing tasks

First create a config file as documented here. You can also reference the examples for Kasiopea mode and CMS mode.

pisek test

This command tests the task in the current directory. It tests all task parts (generator, checker, solutions and judge).

Task testing overview

What pisek verifies:

• Samples exist
• The generator generates inputs
  • Generator is deterministic
  • Generator respects seed on seeded inputs
• The checker accepts all inputs
• The judge works
  • It accepts the samples
  • It doesn't crash on malicious output
• The solutions finish as expected
  • They get the expected number of points
  • They succeed/fail on each subtask as expected
• Data files (inputs and outputs) are valid
  • They are in the correct encoding
  • They don't contain unprintable characters
  • They have a newline at the end
  • The files are reasonably small
• The task is complete
  • A CMS judge has no redundant lines in its stdout/stderr
  • If solution_for_each_subtask=on, there exists a dedicated solution for each subtask

Testing given programs

For fast testing of only the solution solve_cool.cpp use:

pisek test solution solve_cool

Similarly the generator can be tested using:

pisek test generator

Cleaning

Pisek can create a lot of files used for testing. Remove them by running:

pisek clean

Visualization

For visualizing the running time for each solution and testcase:

pisek test --testing-log  # test the task
pisek visualize      # visualize
