Consider printing neatly the silly text “This week has seven dates in it ok” in a column with width M = 11. This is represented as the printing neatly instance M;l1, ... , ln=11; 4, 4, 3, 5, 5, 2, 2, 2. (a) Fill in the birdAdvice[0..n] and cost[0..n] tables for this example. The original instance, its solution, and its cost are in the bottom row.(b) When filling in this last row, give solutions and costs associated with each of the possible bird answers. explain in detail
Select an intelligent optimization method (such as tabu search, simulated annealing, genetic algorithm, ant colony optimization, particle swarm optimization, or other methods) and using programming language to implement it to solve a traveling salesman problem or a functional optimization problem.(For TSPs, you can choose any TSP problem from https ://people.sc.fsu.edu/ jburkardt/datasets/tsp/tsp.html to solve, but I suggest a median scale is OK, such as FRI26 with 26 cities. For function optimization, search the minimal value of f(x), and f(x) = −∑n i=1 sin(xi)(sin(ix2 i /π)) 2m, where n = 10,m = 10, subject to 0 < xi < π,i = 1,...,n. There are n! local optima and the global minimum value for n = 10 is f(x∗) = −9.660152. ) please give me python program code..thanks
Correct answer will be upvoted else downvoted. table can be addressed as a square shape with stature h and width w, isolated into h×w cells. Let (i,j) signify the cell in the I-th line and the j-th segment of the square shape (1≤i≤h; 1≤j≤w). Into every cell of the table you can either put a plate or keep it unfilled. As every visitor must be situated close to their plate, you can just put plates on the edge of the table — into the first or the last line of the square shape, or into the first or the last segment. Officially, for every cell (i,j) you put a plate into, no less than one of the accompanying conditions should be fulfilled: i=1, i=h, j=1, j=w. To make the visitors agreeable, no two plates should be placed into cells that have a typical side or corner. All in all, if cell (i,j) contains a plate, you can't place plates into cells (i−1,j), (i,j−1), (i+1,j), (i,j+1), (i−1,j−1), (i−1,j+1), (i+1,j−1), (i+1,j+1). Put whatever number plates on the table as could be…
Suppose that you want to schedule some final exams for CS courses with following course numbers: 555, 137, 157, 203, 261, 115, 118, 156. Suppose also that there are no students in common taking the following pairs of courses: 555‐137, 555‐157, 137‐157, 555‐203, 555‐261, 137‐261, 203‐261, 555‐115, 137‐115, 203‐115, 261‐115, 555‐118, 137‐118, 555‐156, 137‐156, 157‐156. Schedule the exam using the fewest number of slots.

Ahmad wanted an algorithm to list her favourite games. He wanted to be able to enter a favourite game to be added to the list. He did not want duplicated on the final list but did want to be told, having entered proposed game, either that it was a duplicate or that had been added to the list. Or he can enter the list of favourites and then the algorithm will delete the duplicated one ⦁ Build your algorithm by OUBUILD and then provide screenshots showing that he has entered games twice and not added to the list. Ahmad will keep add his favourite game until he press -1 to exit from the loop can i get an answer that would be easy to copy on oubuild please
Consider printing the ridiculous text "This week has seven days in it, okay" neatly in a column with width M = 11. This is illustrated by the neatly printed example M;l1,..., ln=11; 4, 4, 3, 5, 5, 2, 2, 2. (a) For this case, fill in the birdAdvice[0..n] and cost[0..n] tables. The lowest row contains the initial instance, its solution, and its cost. (b) Fill in the last row with the solutions and costs for each of the potential bird answers. describe in depthConsider printing the ridiculous text "This week has seven days in it, okay" neatly in a column with width M = 11.

Cookie Monster Inc. is a company that specializes in the development of software that tracks web browsing history of individuals. A sample of browser histories is provided in the files CookieMonsterBinary and CookieMonsterStacked that indicate which websites were visited by which customers. Using binary matrix format, the entry in row i and column j indicates whether web site j was visited by user i.Refer to the Appendix for instructions on how to perform association rules using the Analytic Solver Platform. Using a minimum support of 4% of the transactions (800 of the 20,000 total transactions) and a minimum confidence of 50% to generate a list of association rules. Review the top 14 rules. Use the files CookieMonsterBinary and CookieMonsterStacked to solve this problem using Analytic Solver. The data in this files is in binary matrix format meaning that each row indicates which iPad features and accessories a customer selected. In the Association Rules dialog box, enter 800 for…
Given webpages {A, E, F} and links {A→F, F→A, F→E, E→F, A→E}. Then, the PageRankPr of a website Xiis calculated withPr(Xi) = (1 − d) + d(PXj→XiP r(Xj )out(j))where out(j) denotes the number of outgoing links from a webpage Xj . Understand thisproblem as an equation system problem and assume d = 0.5. What are then the estimatedPagerank values of the nodes A, E, F?

The New York Knicks and the Chicago Bulls are readyfor the best-of-seven NBA Eastern finals. The two teams areevenly matched, but the home team wins 60% of the gamesbetween the two teams. The sequence of home and awaygames is to be chosen by the Knicks. The Knicks have thehome edge and will be the home team for four of the sevenscheduled games. They have the following choices (hometeam is listed for each game):Sequence 1: NY, NY, CHIC, CHIC, NY, CHIC, NYSequence 2: NY, NY, CHIC, CHIC, CHIC, NY, NYUse simulation to show that either sequence gives the Knicksthe same chance of winning the series.
Description please. Suppose the economies of the world use a set of currencies C1, . . . , Cn; think of these as dollars, pounds, Bitcoin, etc. Your bank allows you to trade each currency Ci for any other currency Cj, and finds some way to charge you for this service. Suppose that for each ordered pair of currencies (Ci, Cj ), the bank charges a flat fee of fij > 0 dollars to exchange Ci for Cj (regardless of the quantity of currency being exchanged). Describe an algorithm which, given a starting currency Cs, a target currency Ct, and a list of fees fij for all i, j ∈ {1, . . . , n}, computes the cheapest way (that is, incurring the least in fees) to exchange all of our currency in Cs into currency Ct. Also, justify the its runtime. [We are expecting a description of the algorithm, as well as a brief justification of its runtime.]
