Expert Solution & Answer
Chapter 3, Problem 12E
Explanation of Solution
State:
- The state space in here is a tree of depth one, that consists of all states successors of the initial state.
- There is no distinction between depth-first search and breadth-first search on such a tree.
- If the sequence length is unbounded, then the root node will have infinitely many successors, so that, only
algorithms which test for goal nodes as we generate successors can work...

Reasons for not being a practical approach:
- An important disadvantage of collapsing the search space like this is if users discover that a plan starting with the action “unplug your battery” can’t be a solution, there ...

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.

Input
The first line…
The problem states that there are five philosophers sitting around a circular table. The philosophers must alternatively think and eat.
Each philosopher has a bowl of food in front of them, and they require a fork in each hand to eat. However, there are only five forks available. You need to design a solution where each philosopher can eat their food without causing a deadlock.

You are given two integers n and k.
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.

- Refer to the diagram below showing eating arrangements: a round table on which is set a large serving bowl of spaghetti, five plates, one for each philosopher, and five forks. A philosopher wishing to eat goes to his or her assigned place at the table and, using the two forks on either side of the plate, takes and eats some spaghetti. The problem: Devise an algorithm that will allow the philosophers to eat and must satisfy mutual exclusion (no two philosophers can use the same fork at the same time) while avoiding deadlock and starvation.arrow_forwardThe rook is a chess piece that may move any number of spaces either horizontally or vertically. Consider the “rooks problem” where we try to place 8 rooks on an 8x8 chess board in such a way that no pair attacks each other. a. How many different solutions are there to this?b. Suppose we place the rooks on the board one by one, and we care about the order in which we put them on the board. We still cannot place them in ways that attack each other. How many different full sequences of placing the rooks (ending in one of the solutions from a) are there?arrow_forwardThe Knapsack Problem is a famous computer science problem that is defined as follows: imagine you are carrying a knapsack with capacity to hold a total of weight C. You are selecting among n items with values A={a_1, a_2, ... , a_n} and associated weights W={w_1, w_2, ... , w_n}. Here the weights and values are all positive (but not necessarily unique). You wish to maximize the total value of the items you select not exceeding the given weight capacity, i.e. maximize sum_{a in A} such that sum_{w in W} <= C. Please note that you can only select your items once. a) We can reformulate this as a 2D bottom-up dynamic programming problem as follows. Define T_{i,j} as the highest possible value sum considering items 1 through i and total weight capacity j (j <= C). What is the base case i.e. T_{0,j} for all j and T_{i,0} for all i?, and What is the loop statement?arrow_forward
- Implement an algorithmic solution, indicating which states are valid and which are not, and model the space of the following problem: An interest group from a small town decided to sue a company for commercial abuse. For this, the people have organized themselves and decided to send 3 representatives, who will have to travel in a Van to the city where the lawsuit will be filed. The company to be sued, upon learning of these actions, has decided to send 3 lawyers to persuade the representatives, who will also travel in the same Van for that purpose. The community must file the class action suit under these conditions: - The three applicants must reach the destination city; - Only two people can travel per trip in the Van (small town - city, city - small town); - There can never be more lawyers than plaintiffs in any one place (either in the small town or city) because the lawyers can persuade the plaintiffs and as a consequence, the lawsuit would not be made; - The Van cannot be…arrow_forwardonsider the challenge of determining whether a witness questioned by a law enforcement agency is telling the truth.

- The Harvard robotics club has organized a Robothon. n robots are placed alongthe edge of a circular area at the middle of the OAT(open air theatre). Each robot will move along arbitrary tracksinside the circle while leaving behind a heat signature along its trail. However, they have beenprogrammed not to cross their own trail or the trail of another robot, neither will they ever moveout of the circle. In case a pair of robots i and j meet at any point, they are removed from the sceneand the club will pay a reward sum of M[i, j] to the owners of these robots. Note that some robotscan keep moving infinitely without ever meeting another one. Given the reward matrix M whereM[i, j] = M[j, i], design a polynomial time algorithm that determines the maximum money theclub might potentially end up spending.

Child Ehab has a piece of Cut and Stick with an exhibit an of length n composed on it. He intends to snatch some scissors and do the accompanying to it: pick a reach (l,r) and cut out each component al, al+1, ..., ar in this reach; stick a portion of the components together in a similar request they were in the exhibit; end up with different pieces, where each piece contains a portion of the components and each component has a place with some piece. All the more officially, he segments the arrangement al, al+1, ..., ar into aftereffects. He thinks a dividing is lovely if for each piece (aftereffect) it holds that, assuming it has length x, no worth happens rigorously more than ⌈x2⌉ times in it.

Fortunately, Michael knows precisely what the jail resembles from within, particularly since it's actual straightforward. The jail can be addressed as a square shape a×b which is partitioned into abdominal muscle cells, each addressing a jail cell, normal sides being the dividers among cells, and sides on the edge being the dividers prompting opportunity. Prior to condemning, Michael can ask his companions among the jail representatives to make (all around stowed away) openings in a portion of the dividers (counting dividers among cells and the furthest dividers). Michael needs to have the option to escape the jail after this, regardless of which cell he is set in. Nonetheless, he likewise needs to break as couple of dividers as could be expected.
