Suppose you needed to find out if anyone in a group of people had a birthday on a particular date. One approach would be to ask the members one at a time. If you took this approach, the occurrence of what event would tell you that there was such a person? What event would tell you that there was no such person? Now suppose that you wanted to find out if at least one of the positive integers has a particular property and you applied the same approach of systematically testing the integers one at a time. If, in fact some integer has the property, how would you find out? If, however, no integer has the property, how would you find out? Is the task of testing to see if a conjecture is true necessarily symmetric with the task of testing to see if it is false?

- A group of individuals are living on an island when a visitor arrives with an unusual order: all blue-eyed people must leave the island immediately. Every evening at 8:00 p.m., a flight will depart. Everyone can see everyone else's eye colour, but no one knows their own (nor is anyone allowed to tell them). Furthermore, they have no idea how many people have blue eyes, but they do know that at least one person has. How long will it take for the blue-eyed individuals to leave?arrow_forwardSuppose you are going to simulate GPS positioning using 4 satellites. 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. A = .00415783 seconds B = .00400006 seconds C = .00837010 seconds D = .00712225 secondsarrow_forwardApply gaussian random walk(walking in a random direction with each step of length 1. i.e. each time at random theta it will walk cos(theta) at x, sin(theta) at y). What is the probability that the walk starting at (0,0) will end at (5,5)? How to simulate it in python?arrow_forward
- 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…arrow_forwardConsider the case when several persons play the wireless phone game. They send a message from the first person until the last one and the message gets distorted. Simulate this process according to your own distortion rules.arrow_forwardWhen faced with the challenge of searching a text string for any one of a specified set of k patterns, how would you modify the Rabin-Karp method? Beginning with the assumption that all k patterns have the same length, we may proceed. Then how about making your approach more broad so that varying lengths of patterns may be accommodated?arrow_forward
- During the 17th century, gambler de Méré asked Blaise Pascal an explanation for his game losses. His question was solved by Pascal and Fermat, and yielded the foundations of the theory of probability. Gamblers used to bet on the event of getting at least one ace in four rolls of a dice. As a game variation, De Méré proposed to use two die and roll them 24 times with a bet on having at least one double ace. De Méré thought the games were equivalent but he lost consistently. Explain why? Write a simulation program to empirically determine which one dice/two die game is more likely to win.arrow_forwardImagine you have 331 sheep, and you are going to use primitive counting to write a tally stick for the King. Suppose you carry out the procedure as usual, filling the pens with sheep, and liberating the sheep from pen 2 (and any extra sheep); then doing it again, doing it again, etc., until you get down to one sheep.How many sheep will you have in the first pen After one round? After two rounds? After three rounds?arrow_forwarda) Explain on Simulated Annealing algorithm behaves at very high temperatures, and how it behaves at very low temperatures. (b) Imagine the implementation of Simulated Annealing algorithm in real life. Let's say, you have a caretaker at your home. Your home has a garden and it has a fountain with a network of pipes that contains 150 faucets. You informed your caretaker that you are going for short holiday to Langkawi for 3 days and when you return you would like the fountain to spray as high as possible. Your caretaker knows that it is impossible to check all faucets within 3 days to obtain an optimal setting. You can use Simulated Annealing algorithm to maximize the height of the fountain, also can assume whether a faucet can be ON or OFF and measuring the water height. Adding to that, you can make any other assumptions required for this scenario, explain clearly using Simulated Annealing algorithm.arrow_forward
- I see now how the histogram works, but the issue I'm having is if I put in the number 3 it only shows * (1 astrick) and I need it to match the index correctly.arrow_forwardImplement 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_forwardTom and Jerry recently saw the movie inception. Inspired by that movie they decided to play a complicated game. Analogous to the movie inception, Jerry is the dreamer and Tom is the thief who enters Jerry's dream in order to extract the secret code. Tom wins the game if he is able to extract the secret code, else Jerry wins the game. Note that here Tom has to extract the idea from Jerry. Tom after performing a lot of mathematical analysis finally ended up to one last step for which he requires a little computation. He has got an array of positive integers. If atleast one of them is prime, he will be able to crack the secret code and win the game, else Jerry wins the game. Input The first line contains a single integer t (1≤t≤106) the number of test cases. Description of each test case is as follows. The first line of each test case contains a single integer n (1≤n≤2⋅106) the number of elements in the array. The second line of each test case contains n positive integers…arrow_forward
