WebAbstract: We present randomized approximation algorithms for the maximum cut (MAX CUT) and maximum 2-satisfiability (MAX 2SAT) problems that always deliver solutions of expected value at least.87856 times the optimal value. These algorithms use a simple and elegant technique that randomly rounds the solution to a nonlinear programming … Web3 de ago. de 2006 · Download PDF Abstract: The independence numbers of powers of graphs have been long studied, under several definitions of graph products, and in particular, under the strong graph product. We show that the series of independence numbers in strong powers of a fixed graph can exhibit a complex structure, implying that … Web24 de dez. de 2012 · Using the above argument, Leung et al. recently found the first two examples of graphs whose entanglement-assisted capacity exceeds the Shannon capacity.Their graphs are based on the exceptional root systems and , giving a graph on 63 vertices such that and a graph on 157 vertices such that .They also show that their … derivative of tan 2 theta
