4. For this problem, you may leave your answers unreduced. (a) In how many ways can the letters in the word ALGORITHM be arranged? (b) In how many ways can the letters in the word ALGORITHM be arranged if the letters RI must appear next to each other in that order?
3.9. Is the reduced echelon form of a matrix unique? Justify your conclusion. Namely, suppose that by performing some row operations (not necessarily fol- lowing any algorithm) we end up with a reduced echelon matrix. Do we always end up with the same matrix, or can we get different ones? Note that we are only allowed to perform row operations, the "column operations"' are forbidden.
We consider the Traveling Salesman Problem with the cost matrix 0 87 1 5 1086 3 7 10 15 9 2 70 5 8 2620 and apply Little's branch and bound algorithm. What is the initial lower bound on possible solutions at the very first step of the algorithm? Which edge (which entry of the cost matrix) is used for the first inclusion/exclusion branching? Enter the indices of vertices at both end points of this edge without any separators between them. (For example,if the edge (12) (or,in other words,the matrix entry c12) is chosen for inclusion/exclusion, enter 12 in the text box.) What is the lower bound on the solutions in the exclusion branch (after the fırst inclusion/exclusion branching)?
(c) Suppose that F - Bin(2m + 1, 5). Use Chebyshev's inequality to bound P[F > m]. From (c), deduce that the probability of a decoding error in the binary sym- metric channel (BSC) with symbol error probability p = can be made arbitrarily small by using a sufficiently long repetition code.

6. A researcher develop one new prediction algorithm. He want to find out whether hisalgorithm predict a situation faster than the current method. He test his algorithm to makea prediction base on 4 sets of data. He recorded the computation time in microsecond andcompare it with current method and standard method.

Determine how many times the innermost loop will be iterated when the following algorithm segment is implemented and run. (Assume that a, b, c, and d are positive integers. Assume a ≤ b and c ≤ d.) for i := a to b for j := c to d [Statements in body of inner loop. None contain branching statements that lead outside the loop.] next j next i

Consider the following network, where each number along a link represents the actual distance between the pair of nodes connected by that link. The objective is to find the shortest path from the origin to the destination. (a) For the forward recursion formulation of this problem, how many stages are there, and what arethe states for each stage? Stage 1: n = 1 Stage 2: n = 2 origin) ( Stage 3: n = 3 S A B C (b) Use forward recursion to solve this problem. However, instead of using the usual tables, show your work graphically. In particular, start with the given network, where the answers already are given for f (Sn) for four of the nodes; then solve for and fill in f2 (B) and fi* (0). Draw an arrowhead that shows the optimal link to traverse out of each of the latter two nodes. Finally, identify the optimal path by following the arrows from node O onward to node T. (c) Use forward recursion to solve this problem by manually constructing the usual tables for n = 3, n = 2, and n = 1.…
