- 12 main categories: compress 4 different test data sets, with 3 speed brackets for each test. Participants may compete in one or more categories.
- Student category: optimize a given compressor using parameter file.
What is GDCC
The competition is for software engineers, researchers, students and enthusiasts in the field of lossless data compression. The contest includes several main categories open to anyone who meets the general requirements, as well as a special category for students. We test compressors under the following scenarios:
Test 1:
Qualitative-data compression
Filtered Chinese Wikipedia DB data
In 3 categories
Test 2:
Quantitative-data compression
16-bit multispectral images, 16-bit integer and 32-bit floating point telemetry data
In 3 categories
Test 3:
Mixed-data compression
Preprocessed ARM64 executable files mixed with scientific data containing 32-bit floating-point numbers and 32-bit integers
In 3 categories
Test 4:
Small-block-data compression
Mixture of Test 1 and Test 3 data to be compressed independently in 64 KiB blocks but allowing random-access decompression in 8 KiB blocks
In 3 categories
Test 5:
Student test
Participants must generate a parameter file for the provided compressor that minimizes compressed-data size for Test 1 data
Optimize a given compressor using parameter file.

Main Rules
• 5,000 EUR, 3,000 EUR, and 1,000 EUR awards for first, second, and third places, respectively, in all 12 main categories and the student category. Each category has its own prizes.
• 500 EUR award each for places 4–13 in the student category.
• 20,000 EUR grand prize for the winner in block-test rapid category who meets certain conditions.
• 5,000 EUR “gap” prize in all 12 main categories when the first-place competitor wins by a sufficiently large margin over the second-place competitor.
• Submit compressors beginning June 21, 2021 to join the leaderboards.
• Compressor submissions must be executable files for Windows or Linux.
• Leaderboards updated monthly (or more often)
• Deadline for new and updated submissions is November 15, 2021.
• Results to be announced by December 15, 2021.
• Prizes awarded in accordance with the final leaderboards.
- In all tests, the data we use for scoring is private.
- We provide sample data, or training data, that is of the same nature and similar to, yet different from, the private test set.
- We accept binary submissions; source codes are unnecessary unless required by library or software-block licenses on which the submitted compressor is based.
