As Himuro looks out over a sunset colored ocean from her room in the resort hotel, Yukimura barges in saying, "we have to do now what we couldn't do this afternoon." The next day, it's finally time to make their presentations in front of a huge audience.

Just like the traveling salesman 
problem, people call this NP-hard.

эту задачу тоже называют NP-трудной.
