수학동아 - 폴리매스
함께 풀고 싶은 문제
창의력을 기를 수 있는 수학 문제 또는 퍼즐을 내는 곳입니다.
3차원 정육면체 상자의 모서리에서 알까기를 한다.
한 사람당 3개의 바둑돌을 서로 다른 세꼭짓점에만 배치할 수 있다.
또한, 바둑돌을 칠때는 모서리를 따라서만 바둑돌이 움직인다고 하고, 공격을 받은 바둑돌은 무조건 게임에서 제외된다.
이때, 이 게임에 필승전략이 존재할까?
존재하지 않는다면 이유를 설명하고, 존재한다면 누구에게 존재하는지와 그 전략을 설명해보자.

바둑돌은 번갈아가면서 하나씩 놓나요? 아니면 먼저 순서 사람이 3개를 먼저 다 놓나요?

정육면체의 꼭짓점을 윗면 왼쪽 위부터 반시계방향으로ABCD, 밑면 왼쪽 위부터 반시계방향으로 EFGH라고 할때, A,B,D에 검은돌 배치, F,G,H에 흰돌 배치합니다!
