Plagiarism detector and Ghost mode

Plagiarism detector

In the real contest there are probabilities that users cheat others code or help each other. In order to prevent this risk, it is necessary to build a service that can analyze source code submissions. I'll build a new service so that omegaup platform can check for potential plagiarism when source codes were evaluated.

Ghost mode

Users often want to replay past contest. When users replaying any past competition they will be able to see a replay of the scoreboard exactly as recorded during the original competition. This is important because it lets users to simulate their performance with the original scoreboard. I'll build ghost mode feature on top of omegaup platform.
