4. Approximating Clique. The Maximum Clique problem is to compute a clique (i.e., a complete subgraph) of maximum size in a given undirected graph G. Let G = (V,E) be an undirected graph. For any integer k ≥ 1, define G(k) to be the undirected graph (V (k), E(k)), where V (k) is the set of all ordered k-tuples of vertices from V , and E(k) is defined so that (v1,v2,...,vk) is adjacent to (w1,w2,...,wk) if and only if, for...
Create a fraction class. This will have two attributes, a numerator and a denominator, both int. This class will have constructors accessors and mutators (for the attributes) a toString method which will allow us to print the fraction in the form 3/4 an Add method so we can add two fractions a subtract method (subtracts one fraction from the other) a multiply method (multiply two fractions) a divide method (divides one fraction by the other) DO NOT (for now) worry...
2. Consider the torsional system shown in Figure 2. Assume damping is negligible, i.e., ok/J. From the free vibration response, it is observed that the natural frequency of the system is w Then increase the moment of inertia of the disk to JJ, and the free vibration response shows that the natural frequency is reduced to a,2. Calculate J and k Express Jand k in terms of ω 1 and ω". Hint: Apply a, = vk/J to both cases. 0,T...
A real symmetric matrix B e Rnxn (i.e. BT = B) is said to be positive definite if all of its eigenvalues 11, 12, ..., In are positive. (Recall that is an eigenvalue of B if and only if there exits a nonzero vector t such that Bt = it). Show that B-1 is also positive definite. That is, you need to show that all the eigenvalues of B-1 are also positive. (Hint: consider equation Bt; = liti for all...
7. Let E C R be nonempty, n E N, and K, L E Z such that K/n is an upper bound for E, but L/n is not an upper bound for E. (a) Show that there exists an for E, but (m - 1)/n is not an upper bound for E. (Hint: Prove by contradiction, and use induction. Drawing a picture might help) m < K such that m/n is an upper bound integer L (b) Show that m...
Compute the exponentiation x^e mod 29 of x = 5 with both variants of e from above* for n = 4. Use the square-and-multiply algorithm and show each step of your computation. *above, referring to the formulas e = 2^n + 1 and e = 2^n -1
Anharmonic oscillator. Hydrogen bromide, H8Br, vibrates approximately according to a Morse potential VM(r) = Dell-e-ck/2De)i/2(r-re) , with De= 4.810 eV, = 1.4144 A, and k= 408.4 N m-1. With a0-Vk/a, the energies of the stationary states in a Morse potential are En (n + 1/2)2. (A) On the same graph, plot the Morse potential and the harmonic potential as a function of bond length (from 0.7 to 2 %). Use the software of your choice to generate this plot. (B)...
