Universal vulnerability in strong modular networks with various degree distributions between inequality and equality
Yukio Hayashi, Taishi Ogawa
Generally, networks are classified into two sides of inequality and equality with respect to the number of links at nodes by the types of degree distributions. One side includes ma…

Fast convergence to an approximate solution by message-passing for complex optimizations
Yukio Hayashi
Message-passing (MP) is a powerful tool for finding an approximate solution in optimization. We generalize it to nonlinear product-sum form, and numerically show the fast convergen…
