General information

The Online GPT 2020

There will be an additional Online-GPT in December with the final on Sunday, December 13th. Unlike the regular GPTs, the Online-GPT won’t be a qualifying competition to the IPT, but it will be the ideal tournament to feel the spirit of the GPT and IPT – even without having to travel.

Furthermore, the problems for the Online-GPT are chosen such that they can be worked on at home without special lab equipment. Therefore, the Online-GPT is also a convenient possibility to become familiar with this kind of competition and to be perfectly prepared for the next qualifying GPT, that probably will take place two or three months before the IPT 2021. Finally, for the participants of the Online-GPT there will be a small bonus for the physics fights in the qualifying GPT: You will be allowed to submit your Online-GPT-problem again (with a maximum of two Online-GPT-problems per team).

The Online-GPT 2020 is organized by the GPT network. The competition is supported by the German Physical Society (DPG).

For the winners

We will determine the best reporter, the best opponent, the best reviewer, and of course the best team of the tournament. The winning team will be supported in writing an article on one of their problems in order to submit it to an international journal.

The Problems

The problems of the Online-GPT can be found here.


There will be no registration fee. The final registration has to be done until one week before the tournament. However, for a better planning of the competition, we kindly ask you to contact us non-commitally as soon as possible (not later than mid-November). We will inform everyone who has contacted us about what is required for the final registration. Furthermore, in case you have questions, please write us: .

Teams or single participants

Teams should consist of 3 to 6 students. However, we will also help single participants without team to join a team. It is sufficient to work on one problem to participate.
