What happens when a topic for a Bachelor's thesis is submitted and while the student writes their thesis, a paper discussing the exact same topic is published by researchers of a different university?
This is merely a scenario. I'm not in this situation. But I feel like it concerns me a lot as I would be, had I written my theses 3 years earlier, as I received an email today informing me that the topic I proposed to a chair would be a good topic but has already been looked into by 5 researchers at a French university and the French Institute for Research in Computer Science and Automation somewhat short of 3 years ago. The topic of their paper exactly matches what I planned to write about, so I think this happening is plausible. However, I can't seem to find information online about how it would be handled.
In such a scenario, is the student allowed to finish their thesis? How would the publication of the paper impact the requirements concerning the thesis?
Had this happened to me (with the topic I proposed), I would've suddenly have access to everything I wanted to find.
Should the field or location matter: I'm a computer science student in Germany.
