In the sequential algorithm, what happens after there are no more calls in the current direction?

In the sequential algorithm, what happens after there are no more calls in the current direction?

• A. Change direction
• B. Continue in the same direction
• C. Stop and idle
• D. Return to entry floor

Answer: (A)

In the sequential algorithm, the system serves all requests in the direction it is currently moving. When there are no more calls ahead in that direction, the logical next step is to reverse direction and look for requests in the opposite direction. This keeps the movement efficient and ensures any waiting calls behind or on the other side are eventually served. If, after reversing, there are no requests anywhere, the elevator would idle. So, the correct action when there are no more calls in the current direction is to change direction.
