Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.

Question

5) Give a general form for T(n) for n >= 2.

Suppose that T(0)
= a and T(1) = b are some constants. Define the running pairwise average as, for n > 0,
T(n + 2)
= (T(n + 1) + T(n)] .
We are interested in the long term behavior, i.e., what does T(n) look like as n → oo?

We now consider two sound waves with different frequencies which have to the same amplitude. The wave functions of these waves are as follows: y1 (t) = A sin (2πf1t) y2 (t) = A sin (2πf2t) 1) Using any computer program, construct the wave dependency graph resultant y (t) from time t in the case when the frequencies of the two sound waves are many next to each other if the values are given: A = 1 m, f1 = 1000 Hz and f2 = 1050 Hz. Doing the corresponding numerical simulations show what happens with the increase of the difference between the frequencies of the two waves and vice versa.
Write a Python program to create a Markov model of order k, and then use that model to generate text. Our Markov model will be stored in a dictionary. The keys of the dictionary will be k-grams, and the value for each key will also be a dictionary, storing the number of occurrences of each character that follows the k-gram. Note how, for instance, the key 'ga' in the dictionary has the value {'g': 4, 'a': 1}. That is because, following 'ga' in the input text, the letter 'g' appears four times and the letter 'a' appears one time. write the functions: get_grams(text, k): Returns a dictionary of k-grams as described above, using the input string text and the given positive integer k. Do not form k-grams for the last k characters of the text. combine_grams(grams1, grams2): Takes two k-gram dictionaries and combines them, returning the new combined dictionary. All key-value pairs from both dictionaries should be added into the new dictionary. If a key exists in both dictionaries, then…
We can implement requests to the waiter as either a queue of requests or as a periodic retry of a request. With a queue, requests are handled in the order they are received. Th e problem with using the queue is that we may not always be able to service the philosopher whose request is at the head of the queue (due to the unavailability of resources). Describe a scenario with 5 philosophers where a queue is provided, but service is not granted even though there are forks available for another philosopher (whose request is deeper in the queue) to eat.If we implement requests to the waiter by periodically repeating our request until the resources become available, will this solve the problem described in the above Exercise? Explain.
Consider a divide-and-conquer algorithm that calculates the sum of all elements in a set of n numbers by dividing the set into two sets of n/2 numbers each, finding the sum of each of the two subsets recursively, and then adding the result. What is the recurrence relation for the number of operations required for this algorithm? Answer is f(n) = 2 f(n/2) + 1. Please show why this is the case.
A wave is modeled by the wave function: y (x, t) = A sin [ 2π/0.1 m (x - 12 m/s*t)] y1 (t) = A sin (2πf1t) y2 (t) = A sin (2πf2t) Using any computer program, construct the wave dependency graph resultant y (t) from time t in the case when the frequencies of the two sound waves are many next to each other if the values are given: A = 1 m, f1 = 1000 Hz and f2 = 1050 Hz. Comment on the results from the graph and determine the value of the time when the waves are with the same phase and assemble constructively and the time when they are with phase of opposite and interfere destructively. Doing the corresponding numerical simulations show what happens with the increase of the difference between the frequencies of the two waves and vice versa.

Given an abstraction of the City Tube Map where each node represents the city’s attraction, plan the trip for the tourist to visit. Start from node 1 that is their hotel, a group of tourists wants to visit all places. However, due to the time limitation, they can only visit each attraction once. To find the best order of places to visit, genetic algorithm can be used to derive the best possible solutions.
