1. This problem exercises the basic concepts of game playing, using tic-tac-toe (noughts and crosses) as an example. We define Xn as the number of rows, columns, or diagonals with exactly n X's and no Os. Similarly, On is the number of rows, columns, or diagonals with just n Os. The utility function assigns +1 to any position with X3=1 and -1 to any position with 03=1. All other terminal positions have utility O. For nonterminal positions, we use a linear evaluation function defined as Eval(s)=3X2(s)+X1(s)-(3 02 (s)+ 01(s)). a. Approximately how many possible games of tic-tac-toe are there? b. Show the whole game tree starting from an empty board down to depth 2 (i.e., one X and one on the board), taking symmetry into account.

This problem exercises the basic concepts of game playing, using tic-tac-toe (noughtsand crosses) as an example. We define Xn as the number of rows, columns, or diagonals with exactly n X’s and no O’s. Similarly, On is the number of rows, columns, or diagonals with just n O’s. The utility function assigns +1 to any position with X3 = 1 and −1 to any position with O3 = 1. All other terminal positions have utility 0. For nonterminal positions, we use a linear evaluation function defined as Eval (s) = 3X2(s)+X1(s)−(3O2(s)+O1(s))."Mark on your tree the evaluations of all the positions at depth 2."
Correct answer will be upvoted else downvoted. Computer science. You are given a grid a comprising of positive integers. It has n lines and m segments. Develop a framework b comprising of positive integers. It ought to have a similar size as a, and the accompanying conditions ought to be met: 1≤bi,j≤106; bi,j is a various of ai,j; the outright worth of the contrast between numbers in any nearby pair of cells (two cells that share a similar side) in b is equivalent to k4 for some integer k≥1 (k isn't really something similar for all sets, it is own for each pair). We can show that the appropriate response consistently exists. Input The primary line contains two integers n and m (2≤n,m≤500). Every one of the accompanying n lines contains m integers. The j-th integer in the I-th line is ai,j (1≤ai,j≤16). Output The output ought to contain n lines each containing m integers. The j-th integer in the I-th line ought to be bi,j.
A certain cat shelter has devised a novel way of making prospective adopters choose their new pet. To remove pet owners’ biases regarding breed, age, or looks, they are led blindfolded into a room containing all the cats up for adoption and must bring home whichever they pick up. Suppose you are trying to adopt two cats, and the shelter contains a total of N cats in one of only two colors: black or orange. is it still possible to pick up two black cats with probability ½, given that there is an even number of orange cats in the room? If so, how many cats should be in the room? How many black, how many orange?

You ought to make a variety of n positive integers a1,a2,… ,a to such an extent that the total (a1+a2+⋯+an) is distinguishable by k and greatest component in an is least conceivable. What is the base conceivable most extreme component in a? Input The primary line contains a solitary integer t (1≤t≤1000) — the number of experiments. The solitary line of each experiment contains two integers n and k (1≤n≤109; 1≤k≤109). Output For each experiment, print one integer — the base conceivable most extreme component in cluster a to such an extent that the aggregate (a1+⋯+an) is distinct by k.
On a chess board of r rows and c columns there is a lone white rook surrounded by a group of opponent's black knights. Each knight attacks 8 squares as in a typical chess game, which are shown in the figure - the knight on the red square attacks the 8 squares with a red dot. The rook can move horizontally and vertically by any number of squares. The rook can safely pass through an empty square that is attacked by a knight, but it must move to a square that is not attacked by any knight. The rook cannot jump over a knight while moving. If the rook moves to a square that contains a knight, it may capture it and remove it from the board. The black knights. never move. Can the rook eventually safely move to the designated target square? The figure illustrates how the white rook can move to the blue target square at the top-right corner in the first sample case. The rook captures one black knight at the bottom-right of the board on its way. Rok nd kight lcoes by Chunen Input The first line…
Dingyu is playing a game defined on an n X n board. Each cell (i, j) of the board (1 2, he may only go to (2, n).) The reward he earns for a move from cell C to cell D is |value of cell C – value of cell D|. The game ends when he reaches (n, n). The total reward - is the sum of the rewards for each move he makes. For example, if n = 1 2 and A = 3 the answer is 4 since he can visit (1, 1) → (1, 2) → (2, 2), and no other solution will get a higher reward. A. Write a recurrence relation to express the maximum possible reward Dingyu can achieve in traveling from cell (1, 1) to cell (n, n). Be sure to include any necessary base cases. B. State the asymptotic (big-O) running time, as a function of n, of a bottom-up dynamic programming algorithm based on your answer from the previous part. Briefly justify your answer. (You do not need to write down the algorithm itself.)
By the "n queens problem" we mean the problem of placing n queens on an nXn “chessboard" in such a way that no queen can capture any other on the next move. In class we solved the "8 queens" problem. Write a function that inputs an integer n and returns the number of solutions to the “n queens" problem. Your function should use the one dimensional representation for the board, the algorithm we discussed in class, and no gotos. Test your function with a main program that prompts the user for an integer n. The main program then calls the function n times, once for each number from 1 – n, and then prints the number of solutions to each of these problems, one on a line. For example, if you enter n=5 your program should output: 1. There are 2. There are 3. There are 4. There are solutions to the 1 queens problem. solutions to the 2 queens problem. solutions to the 3 queens problem. solutions to the 4 queens problem. solutions to the 5 queens problem. 5. There are Now, since each time…

All the more unequivocally, for every I from 0 to n selective you have cnti components equivalent to 2i. In one activity, you can pick any one component 2l>1 and partition it into two components 2l−1. You ought to perform q inquiries. Each inquiry has one of two sorts: "1 pos val" — appoint cntpos:=val; "2 x k" — ascertain the base number of tasks you really want to make basically k components with esteem lower or equivalent to 2x. Note that all inquiries of the subsequent kind don't change the multiset; that is, you simply work out the base number of activities, you don't perform them. Input The principal line contains two integers n and q (1≤n≤30; 1≤q≤2⋅105) — the size of cluster cnt and the number of inquiries. The subsequent line contains n integers cnt0,cnt1,… ,cntn−1 (0≤cnti≤106). Next q lines contain inquiries: one for each line.…
Wireless sensor networks are a special kind of network that facilitates communication. Sensor nodes in WSNs relay information to and from a central base station. The computing resources and storage space of a sensor node are limited. Take, for example, an algorithm that can be solved by solving subproblems. Is it preferable to use dynamic programming or divide and conquer to solve these subproblems independently at various sensor nodes? Try to keep your writing short and sweet.
