A decomposition-based multi-objective optimization for simultaneous balance computation and transformation in signed networks

Many social systems have a set of opposite interactions such as friend/enemy, cooperation/competition and support/opposition. In these signed systems, there exist functional imbalances from the system-level view because of the existence of unbalanced interactions. However, it is difficult to compute the unbalance degree and transform unbalanced factors to balanced ones in real signed systems. Earlier studies tackled these two issues separately...
