a.
Explanation of Solution
State space:
- The coordinate space is defined in such a way that the center of the maze is at (0,0), and the maze itself is a square from (-1,-1) to (1,1).
- Initial state: robot at coordinate (0,0), facing North.
- Goal test: either |x|>1 or |y|>1 where (x,y) is the current location...
b.
Explanation of Solution
Size of state space:
- The state first records the intersection at which the robot is currently located at, along with the direction its facing.

1. Now, answer these following questions: (a). Write an algorithm to
figure out how many maximum levels the maze can go up to. (b). Figure
out the complexity of your algorithm.
To create a maze some rooms of a building is connected. Starting room is called Entrance room. From
the entrance room other rooms are there connected from it. However, some rooms of that maze-
building have connected room from it, and some rooms do not have any connected room. Each of the
room can have at most or up to two rooms connected from it. The starting room is the entrance room of
the maze or building. Fore example: It can be any one like the followings:

Bob is playing a game. He and his team have come up with a plan to throw a ball so that it can hit the target object. The target is at a distance of X meters from Bob. He is at a height of Y meters from the ground and the target is at a height of Z meters from the ground. Bob can throw the ball with a certain speed
Task
Determine the speed that he should throw the ball.
Notes
He is aiming at an angle parallel to the ground.
Assume acceleration due to gravity is 10m/s²
Example
Assumptions
• X = 2
• Y=5
• Z=2
Approach
It can be calculated that he needs to fire at speeds 2.58m/s at an angle parallel to the ground respectively. The answers are taken up to 2 decimal places only. Hence, the answer is 2.58 m/s.
Function description
Complete the solve function provided in the editor. This function takes the following 3 parameters and returns the minimum speed required:
• X Represents an integer denoting the distance of the target from Bob
• Y Represents an integer denoting the height of Bob…

- A hungry mouse wants to eat all four fruits in a maze such as the one below, in as few moves as possible.. At each turn the mouse can move any number of squares in one of the directions up, down, left or right, but it is not allowed to enter (or jump over) any walls (i.e., the black squares). Thus, the mouse moves just like a rook in chess. To eat a fruit, the mouse has to stop at that square. Assume that the maze has 4 fruits, and the size of b xh squares. 1. Give a suitable representatión of the states in this searching problem. 2. How many possible actions can the mouse perform at each move?

For each configuration, the only possible moves are to swap the empty tile with one of its neighboring tiles. The goal state for the puzzle consists of tiles 1-3 in the top row, tiles 4-6 in the middle row, and tiles 7 and 8 in the bottom row, with the empty space in the lower-right corner.you will develop two solvers for a generalized version of the Eight Puzzle, in which the board can have any number of rows and columns. A natural representation for this puzzle is a two-dimensional list of integer values between 0 and r · c -1 (inclusive), where r and c are the number of rows and columns in the board, respectively. In this problem, we will adhere to the convention that the 0-tile represents the empty space.tasks:In the TilePuzzle class, write an initialization method __init__(self,…arrow_forwardPlease answer this only in python Alice and Bob play a game. At first, there is only one tree with roots. The players take turns, Alice begins. At one point, Alice has to pick up any empty underground tree roots (or shrubs) and remove them. Bob, on the other hand, has to pick out any part of the empty leaves and remove them from the tree (or trees). (Please note that Bob always takes some depth from the leaves of the first tree.) It is not allowed to skip the turn. The game ends when the player is unable to take a chance. Alice's goal is to reduce the number of turns made by both players, while Bob wants the number to be greater. Considering that they both played very well, how many turns did they make last.

- Note: Answer the question using Java language only. Shaker is the first child who got scholarship into the village. He went to London to study where he finds it very interesting to calculate number of ways of going to point (c, d) from point (a, b) in co-ordinate plane. We can take horizontal and vertical steps only and cannot visit at a point twice. In a step, you can move one unit only. We have to reach to the point (c, d) from the point (a, b) using abs(a-c) + abs(b-d) steps only. Shaker has two sets of points. Set A contains points having X co- ordinate 0 and Y co-ordinates varying from 1 to N (both inclusive). Set B contains points having X co-ordinate K and Y co-ordinates varying from 1 to N (both inclusive). Both sets contain N number of integral points. He wants to calculate the sum of number of ways to going to each point of set B from each point of set A.

- Correct answer will be upvoted else downvoted. Computer science. You have w white dominoes (2×1 tiles, the two cells are hued in white) and b dark dominoes (2×1 tiles, the two cells are shaded in dark). You can put a white domino on the board in case both board's cells are white and not involved by some other domino. Similarly, you can put a dark domino if the two cells are dark and not involved by some other domino. Would you be able to put all w+b dominoes on the board if you can put dominoes both on a level plane and in an upward direction?

The cards with red color should come before those with black color, and cards with small numbers should come before those with big numbers. The cards with images should be in this order: Jack, Queen and King. The game allows player to start by small number of cards, then increase step by step, e.g, 2,3,4, ....n. Design an efficient algorithm that helps a player A to win the game by sorting n number of cards faster than player B. Note that n number of cards which is very large can be obtained by repeating cards with the same number and same color, e.g, card 3 with color red can be repeated m times while marrow_forwardLet's begin with a lesson in roulette. Roulette is a casino game that involves spinning a ball on a wheel that is marked with numbered squares that are red, black, or green. Half of the numbers 1–36 are colored red and half are black and the numbers 0 and 00 are green. Each number occurs only once on the wheel. We can make many different types of bets, but two of the most common are to bet on a single number (1–36) or to bet on a color (either red or black). These will be the two bets we will consider in this project. After all players place their bets on the table, the wheel is spun and the ball tossed onto the wheel. The pocket in which the ball lands on the wheel determines the winning number and color. The ball can land on only one color and number at a time. We begin by placing a bet on a number between 1 and 36. This bet pays 36 to 1 in most casinos, which means we will be paid $36 for each $1 we bet on the winning number. If we lose, we simply lose whatever amount of money we…arrow_forward
