The rules will be similar to the usual rules of the IPT (see IPT website: https://iptnet.info/official-rules/) that in short are also presented here on the website of the GPT (https://germany.iptnet.info/rules/).
However, minor adjustments and amendments have to be made in order to fit the online form. These additional rules will be posted here before the Online-GPT.
Furthermore, there is a simplification on what problems can be challenged: Each team has to announce which problems it has worked on (probably at least three problems per team). Only these problems can be challenged by other teams and the team can only report on the problems that it has announced. Therefore, to participate, it is sufficient if every participant works on one problem.
