임의의 단순 무향 그래프 G=(V, E)의 라인 그래프(Line Graph) L(G)=(V', E') 는 아래와 같이 정의된다.
V'=E이며, E'={(e, e') | e와 e'는 G에서 공통된 인접 정점을 갖는다. }
아래 그림은 어떤 다섯 개의 그래프 G1, G2, G3, G4, G5 의 라인그래프를 나타낸 것이다.
이 중에서 원래 그래프가 한붓그리기가 불가능한 것은?
이 때, L(G2) 와 L(G4) 는 엄연히 다르다는 것에 주의하라.

내가 한붓그리기는 해 줄 수 있는데 혹시 같이 문제 푸실 분
(그래프 이론 안 배운 1인ㅠㅠ)

그래프 이론은 교과과정엔 없는 걸로 알고 있고 조합론을 공부하시면 대부분의 내용이 그래프외 관련있습니다!
