This paper mainly studies a class of generalized sum-of-linear-fractions programming problems which have important applications in finance, economy and computational vision. In this process, we first propose a new method to re-represent the original problem as an equivalent problem (EP) with...

We develop a new tool for studying evolutionary games on complex networks - dynamical approximate master equations (DAMEs).We use DAMEs to predict evolutionary outcomes of two-player repeated games on networks and to study the behavior of nodes and edges during evolution.DAMEs reveal the...
