Chapter 1, Problem 4D
Explanation of Solution
Storing values in the computer:
- The computer will not store the exact values of certain numbers. Rather they store an approximate value.
- For example, the value 0.1 might be stored as 0.10000000000000000555 and in certain situations the approximate values do not create any problems.
- The chaotic behaviour exhibits unpredictability and extreme sensitivity of the initial values.
- If the computer takes approximate values without giving importance to exact value, it might pose problem.
Areas where the chaotic behaviour poses problem:
When trying to multiply a number with larger number...

The puzzle called the Towers of Hanoi consists of three pegs, one of which contains several rings stacked in order of descending diameter from bottom to top.
The problem is to move the stack of rings to another peg. You are allowed to move only one ring at a time, and at no time is a ring to be placed on top of a smaller one. Observe that if the puzzle involved only one ring, it would be extremely easy.
Moreover, when faced with the problem of moving several rings, if you could move all but the largest ring to another peg, the largest ring could then be placed on the third peg, and then the problem would be to move the remaining rings on top of it.
Using this observation, develop a recursive algorithm for solving the Towers of Hanoi puzzle for an arbitrary number of rings.
The Monte Carlo method is used in modeling a wide-range of physical systems at the forefront of scientific research today. Monte Carlo
simulations are statistical models based on a series of random numbers. Let's consider the problem of estimating Pi by utilizing the Monte
Carlo method.
Suppose you have a circle inscribed in a square (as in the figure). The experiment simply consists of throwing darts on this figure
completely at random (meaning that every point on the dartboard has an equal chance of being hit by the dart). How can we use this
experiment to estimate Pi? The answer lies in discovering the relationship between the geometry of the figure and the statistical outcome
of throwing the darts. Let's first look at the geometry of the figure.
Let's assume the radius of the circle is R, then the Area of the circle = Pi * R^2 and the Area of the square = 4 * R^2. Now if we divide the
area of the circle by the area of the square we get Pi / 4.
But, how do we estimate Pi by…
A bunch of people are living on an island, when a visitor comes with a strangeorder: all blue-eyed people must leave the island as soon as possible. There will be a flight out at 8:00pm every evening. Each person can see everyone else's eye color, but they do not know their own (nor is anyone allowed to tell them). Additionally, they do not know how many people have blue eyes, although they do know that at least one person does. How many days will it take theblue-eyed people to leave?

- Bob and Alice want to send each other secret messages that no one else will have access to. They have decided that they will use a locked box to hold the secret messages, and they will drop the box off in each other’s mailboxes. The problem is that if they use a combination lock, they will have to send the combination to the box and someone might intercept it. Here are the materials they have access to: A box that can be locked with a combination lock Two combination locks (the kinds that click shut that you might use on a school locker) Paper Pencil Describe a protocol Bob and Alice can set up to deliver these messages securely.arrow_forwardWhen an author produces an index for his or her book, the first step in this process is to decide which words should go into the index; the second is to produce a list of the pages where each word occurs. Instead of trying to choose words out of our heads, we decided to let the computer produce a list of all the unique words used in the manuscript and their frequency of occurrence. We could then go over the list and choose which words to put into the index. The main object in this problem is a "word" with associated frequency. The tentative definition of "word" here is a string of alphanumeric characters between markers where markers are white space and all punctuation marks; anything non-alphanumeric stops the reading. If we skip all un-allowed characters before getting the string, we should have exactly what we want. Ignoring words of fewer than three letters will remove from consideration such as "a", "is", "to", "do", and "by" that do not belong in an index.

- Computer science. Correct answer will be upvoted else downvoted. Think about a n by n chessboard. Its columns are numbered from 1 to n from the top to the base. Its sections are numbered from 1 to n from the passed on to one side. A cell on a convergence of x-th line and y-th section is indicated (x,y). The fundamental corner to corner of the chessboard is cells (x,x) for all 1≤x≤n. A stage of {1,2,3,… ,n} is composed on the fundamental slanting of the chessboard. There is actually one number composed on every one of the cells. The issue is to segment the cells under and on the principle askew (there are by and large 1+2+… +n such cells) into n associated areas fulfilling the accompanying imperatives: Each district ought to be associated. That implies that we can move from any cell of a locale to some other cell of a similar area visiting just cells of a similar district and moving from a cell to a neighboring cell. The x-th area ought to contain cell on the fundamental…arrow_forwardSuppose you always eat a particular brand of cookies out of the standard-sized package it comes in from the store, which has 4 rows of cookies in equal amounts.

You are going to pretend to be a GPS receiver somewhere on the map and will figure out where you are based on the 4 “signals” you receive. But for you (and for a GPS receiver) all those signals tell you is where the satellite was when it sent the signal, and how long it took for the signal to get from the satellite to you. You need to determine where you could be (Mention distance in terms of grunters chain), based on that amount of time elapsed. The speed of light (R) is 299,792,458 m / s. You need to account for the scale factor of the map. This map has a scale factor of 1:21,283,839. This means that 1 meter on the map equals 21,283,839 meters on the earth’s surface.
