1. The optional actions repeat until the diamond yields the absent outcome, and the sequence then leaves the loop toward the initial action.
2. The paired actions repeat until the diamond yields the affirmative outcome, and the sequence then leaves the loop toward the subsequent action.
3. The paired actions repeat until the diamond yields the negative outcome, and the sequence then leaves the loop toward the following action.
4. The nested actions repeat until the diamond yields the numerical outcome, and the sequence then leaves the loop toward the concurrent action.
