A six-story office building has 10 adjacent offices per floor. Each office contains a wall socket for a terminal in the front wall, so the sockets form a rectangular grid in the vertical plane, with a separation of 3 m between sockets, both horizontally and vertically. Assuming that it is feasible to run a straight cable between any pair of sockets, horizontally, vertically, or diagonally, how many meters of cable are needed to connect all sockets using a star configuration with a single router in the middle?

A six-story office building has 10 adjacent offices per floor. Each office contains a wall socket for
a terminal in the front wall, so the sockets form a rectangular grid in the vertical plane, with a
separation of 3 m between sockets, both horizontally and vertically. Assuming that it is feasible to
run a straight cable between any pair of sockets, horizontally, vertically, or diagonally, how many
meters of cable are needed to connect all sockets using a star configuration with a single router in
the middle?

1. Develop a system of linear equations for the network by writing an equation for each router (A, B, C, D, and E). Make sure to write your final answer as Ax=b where A is the 5x5 coefficient matrix, x is the 5x1 vector of unknowns, and b is a 5x1 vector of constants. 2. construct the augmented matrix [A b] and then perform row reduction using the rref() function. Write out your reduced matrix and identify the free and basic variables of the system. 3. Use MATLAB to compute the LU decomposition of A, i.e., find A = LU. For this decomposition, find the transformed set of equations Ly = b, where y = Ux. Solve the system of equations Ly = b for the unknown vector y. 4. Compute the inverse of U using the inv() function. 5. Compute the solution to the original system of equations by transforming y into x, i.e., compute x = inv(U)y 6. Check your answer for x1 using Cramer’s Rule. Use MATLAB to compute the required determinants using the det() function.

Problem 3: We want to tile an n × 1 strip with 1 x 1 tiles that are green (G), blue (B), and red (R), 2 × 1 purple (P) and 2 × 1 orange (O) tiles. Blue cannot be next to purple tile, and there should be no two purple or three blue tiles in a row (for ex., BBOORGP is allowed, but BBBOGR, PBOGP and OPPRO are not). Give a formula for the number of such tilings. Your solution must include a recurrence equation (with initial conditions!), and a full justification. You do not need to solve it.
Algorithm : (1. Single-destination Shortest Path, 2. Bellman-Ford, 3. Negative-Weight Cycles), Dynamic Programming, RNA Secondary Structure Consider n airports, labelled 1 through n. Each airport maintains a number of direct flights to other airports, represented by an edge with an associated cost. Since travel is currently restricted, one may only book direct flights—no airports will perform any transfers. However, things are beginning to open up again and airports are being slowly cleared to process transfers. These are done in order of label, so the first airport to allow transfers is 1, followed by 2, and so on. Once an airport is allowed to take transfers, flights through that airport may be booked. For example, consider the scenario depicted in Figure 1. When all airports are closed to transfers, flights may only be booked between airports connected by an edge. Thus, a flight from airport 5 to airport 2 may not be booked. However, once airport 1 is allowed to perform…

(c) A common way to define the distance between two nodes is the inverse (or reciprocal) of the link weight.
