1. Consider the FIR system described by H(z) = 1/16(-1 + 9z--2 + 16z-3 + 9z--4 - z-6), and plot the pole-zero locations in the z-plane.(1. Consider the FIR system described by H(z) = 1/16(-1+ 9z--2+ 16z-3+ 9z--4- z-6), and plot the pole-zero locations in the z-plane.)

TSP can be defined as a problem where starting from a node it is required to visit every other node only once in a way that the total distance covered is minimized. After an initial solution a neighborhood solution is selected by an exchange of a randomly selected pair of nodes. The randomly generated neighbor solution is selected if it improves the solution else it is selected with a probability that depends on the extent to which it deteriorates from the current solution.
