tikz automata 가장자리가 겹침

수평으로 배치된 두 가지 상태가 있고 이를 연결해야 합니다(예: A -> B 및 A <- B). 가장자리가 겹치지 않고 다이어그램이 A <-> B가 되지 않도록 가장자리를 배치하려면 어떻게 해야 합니까? 그러나 그 대신 서로 탐색할 수 있고 입력 메시지를 위와 아래에 배치할 수 있다는 것이 보입니다.

 (APPEND_COL) edge[???] node[anchor=east,above,xshift=+3.0em]{delete column} (DELETE_COL)
 (DELETE_COL) edge[???] node[anchor=east,above,xshift=+3.0em]{append column} (APPEND_COL)

나는 설정을 시도했다 ??? 위, 아래로, 왼쪽으로 굽히기=20, 오른쪽으로 굽히기=20이지만 이들 중 어느 것도 의도한 동작을 생성하지 않습니다.

업데이트: 좋아요, 여기 전체 코드가 있습니다. 그리고 또 다른 것은 어떻게 하면 루프를 왼쪽과 오른쪽으로 그렇게 크지 않게 만들 수 있습니까?

답변1

연결선의 방향이 반대이므로 한쪽 선과 다른 쪽 bend left=<value>선이 아닌 두 선 모두에 사용해야 합니다 .bend leftbend right
