COVID inspires to solve a 30-year-old problem in computer science

During the corona epidemic many of us became amateur mathematicians. How quickly would the number of hospitalized patients rise, and when would herd immunity be achieved? Professional mathematicians were challenged as well, and a researcher at University of Copenhagen became inspired to solve a 30-year-old problem in computer science.
