Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. Think about a diagram on k hubs, with numbers from b1 to bk composed on them. For each I from 1 to k: track down such j (1≤j≤k, j≠i), for which (bi⊕bj) is the littlest among all such j, where ⊕ indicates the activity of bitwise XOR (https://en.wikipedia.org/wiki/Bitwise_operation#XOR). Then, draw an undirected edge between vertices with numbers bi and bj in this chart. We say that the succession is acceptable if and provided that the subsequent diagram frames a tree (is associated and doesn't have any straightforward cycles). It is conceivable that for certain numbers bi and bj, you will attempt to add the edge between them twice. All things considered, you will add this edge just a single time. You can track down a model underneath (the image comparing to the main experiment). Succession (0,1,5,2,6) isn't great as we can't arrive at 1 from 5. Notwithstanding,…

3. (Gilbert-Eliot channel model) This exercise introduces a useful channel model in the presenceof burst errors, i.e. we assume that the errors come in a consecutive manner and the channelremains sometime in that state. The channel later returns with some probability to a \goodstate". This is presented in the following figure. Suppose that the transition probabilities are z1 = 10-6 and z2 = 10-1a) Find the average length of an error burst.
