I have a doubt concerning the "broadcast disks and caching" exercise. In question 2, for the LIX part, you are updating the running access probabilities for each page whenever the page appears in the broadcast: p1 is updated at time 1, p2 at time 2, p3 at time 3, p1 at time 4, etc.
In the lecture, however, it is said that the value is updated only when the data item is consumed by the application. This is also shown in the example of slide 25. If we follow this example, we should update p1 at time 1, nobody at time 2, p3 at time 3, etc.
Which convention is the right one?
Thanks a lot.
