Suppose you are trying to make a schedule for use of the auditorium for different clubs in a school. The auditorium can be used in the afternoons from Sunday to Thursday. There are five clubs: Music, Drama, Dance, Photography, Computer. There are a few rules that must be followed: a)The auditorium can be used by only one club on a day. b)Computer club wants to use on Monday or Thursday. c)Drama club wants on Wednesday or Thursday. d)Music club is fine with any day. Dance club wants on Monday or Wednesday. e)Photography club wants on Sunday, Tuesday or Wednesday. Formulate this problem as a CSP. Draw the constraint graph. Show the steps followed by backtracking search algorithm and derive a solution.

Conway's Game of Life: This is a zero person game with the following rules: (see Wikipedia for example) Any live cell with fewer than two live neighbours dies, as if by underpopulation. Any live cell with two or three live neighbours lives on to the next generation. Any live cell with more than three live neighbours dies, as if by overpopulation. Any dead cell with exactly three live neighbours becomes a live cell, as if by reproduction. Remember the oscillator or blinker of 3 cells. You can also find this blinker on Wikipedia. 1 21 1 2 1 21 3. 4 6 4. 6. 4 8. 9 8 9 #1 #2. #3 5.

The distance d between a point p(x, y), where x and y are the coordinates of p, and the center of a circle (a, b), where a and b are the coordinates of the center, is given by the formula: (a, b). r d = (x – a)² + (y – b)² r The point p(x, y) is considered inside the circle if d r. (x, y)' (x', y') Write a Java class called CirclePointthat: a. Reads from the user 2 integer values x and y represent the coordinates of the point p, b. Reads from the user 2 integer values a and b represent the coordinates of the center of the circle, c. Reads from the user a real value r represents the radius of the circle, d. Calculates and prints the distance d (rounded to 2 decimal places) between the point p and the center of the circle, and e. Checks and prints whether the point is inside, on or outside the circle. NOTE: if the radius value is negative, an error message should be shown. Sample Run 1: ==================== Enter the coordinates of the point: 5 7 Enter the coordinates of the center of…
Ball at the wallcontext In a ball-at-the-wall game, children in the schoolyard must throw balls at the school wall to reach lines placed at certain heights. You want to predict how high the ball will hit the wall based on the parameters of the throw. Constraints and information The children are all placed behind a line drawn on the floor, at a known horizontal distance ? from the wall;The initial height at which the ball leaves the child's hand is known;The speed and angle of the throw are known; Modelization Creates a model to determine how high the ball will hit the wall based on the children's distance from the wall and the height, speed and angle of the ball as it leaves the child's hand . Then test your model with the following parameters Distance between the wall and the child: 3.9?; Height of the ball when it leaves the child's hand: 1.05?; Throw Speed: 14.1?/?; Throw angle: 51∘
Example 2: Let f and g be functions from the set of integers to the set of integers defined by f (x)= 2x+3 and g(x)= 3x+2. What is the composition of f and g, and also the composition of g and f?
Ql: The Collatz conjecture function is defined for a positive integer m as follows. (COO1) g(m) = 3m+1 if m is odd = m/2 if m is even =1 if m=1 The repeated application of the Collatz conjecture function, as follows: g(n), g(g(n)), g(g(g(n))), ... e.g. If m=17, the sequence is 1. g(17) = 52 2. g(52) = 26 3. g(26) = 13 4. g(13) = 40 5. g(40) = 20 6. g(20) = 10 7. g(10) = 5 8. g(5) = 16 9. g(16) = 8 10. g(8) = 4 11. g(4) = 2 12. g(2) = 1 Thus if m=17, apply the function 12 times in order to reach m=1. Use Recursive Function.

Q1 Dan has a list of problems suitable for the assignment. The difficulties of these problems are stored in a list of integers a. The i-th problem’s difficulty is represented by a[i] (the higher the integer, the more difficult the problem). Dan is too busy eating saltines to worry about assignment decisions, so he asks Michael to select at least two problems from the list for the assignment. Since there are many possible subsets of the problems to consider and Michael has a life, he decides to consider only sublists (definition follows) of the list of problems. To make grading the assignment easier, Michael wants to pick problems that don’t vary too much in difficulty. What is the smallest difference between the difficulties of the most difficult selected problem and the least difficult selected problem he can achieve by selecting a sublist of length at least 2 of the original list of problems? Definition: A sublist of a list a is any list you can obtain by removing some (possibly 0)…
