We study the computational complexity of finding stable outcomes in hedonic games, which are a class of coalition formation games. We restrict our attention to symmetric additively-separable hedonic games, which are a nontrivial subclass of such games that are guaranteed to possess stable outcomes. These games are specified by an undirected edgeweighted graph: nodes are players, an outcome of t...

Abstract For getting the reactive power control model parameters of PV inverters, a method was proposed to test and identify fault inverters based on symmetric asymmetric sets. Firstly, structure grid-connected inverter is analyzed, be identified are defined. subsequently, according various types amplitudes voltage that may occur in course operation system, overall data set obtained, given by m...
