질문 Question

On slide 10 of lecture 14, we have an iterative algorithm to get a fixed-point.
In the given example, we have a function F that is applied to a vector of incoming states (x0, x1, x2, x3, x4) and returns a vector of the updated states. Moreover, x2 and x4 in this example are both dependent only on x1.

In iteration 2, x1 becomes ⊤. If I understand this algorithm correctly, both x2 and x4 should "see" the same value of x1 in any given iteration, and therefore updates of x2 and x4 should be simultaneous - therefore in iteration 3, both x2 and x4 should update based on the new value of x1. However, the slide shows only x2 getting updated in iteration 3, while x4 gets updated in iteration 4. Could you please help me understand why this is so?
Thank you.

Sorry for the late response.

You are right. x4 in iteration 3 should be ZP, not a bot.

Thanks for catching that slide error
