A mapping application cannot consider every factor to calculate the fastest route in a reasonable amount of time. Instead, the application uses an algorithm that considers only the most important factors such as total distance and traffic congestion along popular routes. This algorithm is using a heuristic brute force approach heuristic tractable problem superpolynomial time to approximate the best route.

Use of XOR function

XOR function or exclusive OR function was introduced in Excel 2013. This function is available under excel logical functions. For the given statement, the XOR function will return true only when either of the statements is true. It returns false when both the statements are true or when both the statements are false.

Let A = {a1, a2, ..., an} and be a set of n positive integer and let T be another integer. Design a dynamic programming algorithm that determines whether there exists a subset of A whose total sum is exactly T. Analyze the time complexity of your solution. For instance, if A = 4, 5, 17, 23, 11, 2 and T = 35 the algorithm should return True because the subset 5, 17, 11, 2 sums to 35. For the same set of numbers if we choose T = 31 the problem has no solution, and the algorithm will return False. When designing the dynamic programming algorithm, please describe the size and dimensionality of the dynamic programming table, and explicitly formulate the recurrence relationship.
Given a chess board, your job is to write a program that takes two squares x and y as input and then determines the number of knight moves on a shortest route from x to y. a b c d e f g h 8 e2 e4 al b2 b2 c3 al h8 al h7 h8 al b1 c3 f6 f6 7 6 01 5 4 3 2 1 T ● a b c d e f g h 8965 4 2 7 3 1 Input Specification Your program should read from an input file, which will contain one or more test cases. Each test case consists of one line containing two squares separated by one space. A square is a string consisting of a letter (a-h) representing the column and a digit (1-8) representing the row on the chessboard. Sample Input
Vehicle routing problems concern the linking of a group of customers who must be visited to a set of vehicles and respective drivers, also involving the programming and sequencing of visits. In the method that is based on the concept of gain, the worst possible situation is assumed: the vehicle leaves the DC with the goods destined for a single customer and, after delivery, the vehicle returns to the DC. Then another customer is inserted in this route. This method is known under the name of: ( ) Clark & Wright ( )Insertion of the furthest point ( ) II - OPT ( ) scan ( )III - OPT

Suppose you are in Canada's Thousand Islands National Park, and in one particular lake there are n small islands that park officials want to connect with floating bridges so that people can experience going between islands without a canoe. The cost of constructing a bridge is proportional to its length. Assume the distance between every pair of islands is given to you as a two dimensional matrix (an example of such a table for n = 8 islands is shown below).

The shape of a limacon can be defined parametrically as r = r0 + cos θ, x = r cos θ, y = r sin θ. When r0 = 1, this curve is called a cardioid. Use this definition to plot the shape of a limacon for r0 = 0.8, r0 = 1.0, and r0 = 1.2. Be sure to use enough points that the curve is closed and appears smooth (except for the cusp in the cardioid). Use a legend to identify which curve is which. use phyton language import mathimport numpy as npimport matplotlib.pyplot as plt%matplotlib inline
Type in Latex **Problem**. Let $$A = \begin{bmatrix} .5 & .2 & .3 \\ .3 & .8 & .3 \\ .2 & 0 & .4 \end{bmatrix}.$$ This matrix is an example of a **stochastic matrix**: its column sums are all equal to 1. The vectors $$\mathbf{v}_1 = \begin{bmatrix} .3 \\ .6 \\ .1 \end{bmatrix}, \mathbf{v}_2 = \begin{bmatrix} 1 \\ -3 \\ 2 \end{bmatrix}, \mathbf{v}_3 = \begin{bmatrix} -1 \\ 0 \\ 1\end{bmatrix}$$ are all eigenvectors of $A$. * Compute $\left[\begin{array}{rrr} 1 & 1 & 1 \end{array}\right]\cdot\mathbf{x}_0$ and deduce that $c_1 = 1$.* Finally, let $\mathbf{x}_k = A^k \mathbf{x}_0$. Show that $\mathbf{x}_k \longrightarrow \mathbf{v}_1$ as $k$ goes to infinity. (The vector $\mathbf{v}_1$ is called a **steady-state vector** for $A.$) **Solution**. To prove that $c_1 = 1$, we first left-multiply both sides of the above equation by $[1 \, 1\, 1]$ and then simplify both sides:$$\begin{aligned}[1 \, 1\, 1]\mathbf{x}_0 &= [1 \, 1\, 1](c_1\mathbf{v}_1 +…

In a hypothetical study of population dynamics, scientists have been tracking the number of rabbits and foxes on an island. The number of rabbits and foxes are determined once a year using high resolution infrared cameras and advanced computer vision methods.Each year, the number of rabbits and foxes are found to change by the following equations: $$ {\Delta}R = round( kr*R - krf*R*F ) $$ $$ {\Delta}F = round( -kf*F + kfr*R*F ) $$ where $ {\Delta}r $ and $ {\Delta} f $ are the changes in number of rabbits and foxes by the end of that year; and R and F are the population sizes at the end of the previous year. kr, krf, kf, kfr are coefficients that depend on the species of rabbits and foxes.With these dynamics, the scientists realize that one or both species can become extinct on the island. At the end of each year, if there are fewer than 2 animals of a kind, the scientists transfer rabbits and/or foxes to make sure there are at least 2 of each kind.Write a function…
An object leaves point P1 with coordinates (−1,0) and travels with velocity v1=1 in a straight line to point P2 with coordinates (0,h) . It then travels with velocity v2=2 in a straight line from P2 to point P3 with coordinates (x , y ). Given x and y values there will be some optimal h value that minimizes the total travel time. Write a program in Scilab containing a function in the form function u = h(x,y) [your code goes here] endfunction u = h(1,2); disp(u); that calculates this optimal h value (to an accuracy of about 10^−6 ) given x and y values as arguments. Your function must work for any positive values of x and y.
