In discussing a page replacement algorithm, one author makes an analogy with a snowplow moving around a circular track. Snow is falling uniformly on the track and a lone snowplow continually circles the track at constant speed. The snow that is plowed off the track disappears from the system. a. For which of the page replacement algorithms discussed in Section 8.2 is this a useful analogy?
b. What does this analogy suggest about the behavior of the page replacement algorithm in question?
