The Sandbox provides Entrants the opportunity to become familiar with the competition platform: formats for input and output files, algorithm submission, evaluation, scoring and leaderboard functioning. The links on this page provide information about the original Beta datasets that have been converted to Challenge 1 format and are accessible through the Sandbox submission. See Challenge 1 for full descriptions of the formulation, file formats, evaluation and scoring.
Please be aware that the problem description, input and output formats, datasets, evaluation, and scoring change for each Challenge of the competition, generally becoming more difficult.
There are no prizes associated with use of the Sandbox; it is for testing purposes only.
