The result makes it possible to estimate energy of graphs without direct computation of eigenvalues. As an illustration, we compute the maximum energy among all graphs with n = 4k vertices, which corresponds to strongly regular graphs found by Koolen and Moulton, and apply our result to conference graphs, computing the asymptotic formula for maximal graph energy. |
