A reactive power optimization is a multi-modal, mixed-variable, multi-constraint and nonlinear planning problem. In the last decades, many computational intelligence-based techniques have been proposed for reactive power optimization problem, such as genetic algorithm (GA), particle swarm optimization (PSO), differential evolution (DE), Tabu search. Recently, a new swarm intelligent algorithm, social cognitive optimization algorithm (SCOA), is proposed by simulating the human competition process. In this paper, it is introduced to solve reactive power problem. Two famous examples: IEEE-57bus and IEEE-118bus system are used to test, simulation results show SCOA is effective.

The use of evolutionary algorithms to solve unconstraint multi-objective problems (MOPs) has attracted much attention recently. However, research on constraint multi-objective algorithms is relatively less. The authors introduce a novel evolutionary paradigm of artificial physics optimization (APO) into constraint multi-objective optimization domain and modify the original mass function and virtual force rules in order to fit constraint multi-objective optimization problems. Moreover the authors present a method of virtual force decreasing to improve the efficiency. Finally, simulation tests show that the algorithm is effective.

Estimation of Distribution Algorithms (EDAs) is a novel evolutionary algorithm originated from Genetic Algorithms. The probability distribution model of promising population is estimated iteratively in EDAs, and the new generation is sampled from the estimated model. An EDA with Gumbel copula is proposed in this paper. In order to estimating the joint, the empirical margins of each variable are estimated separately, and the relationship of variables is presented by Gumbel copula. On the ground of copula theory, the joint is the composite function of the copula and the margins. This algorithm simplifies the operator to estimating the multivariate distribution. The experimental results show that the proposed algorithm is equivalent to some conventional continuous EDAs in performance.
