The problem of optimal capacitor placement (OCP) in three-phase and unbalanced radial distribution systems consists in determining the types, rated power, and in which phases to allocate them, taking into account the ...

This paper presents a parallel distributed model for the Differential Evolution algorithm. The proposed model, Hierarchical Island-Based Model for Differential Evolution, follows a double-hierarchy master-worker scheme and ...

In an evermore competitive environment, power distribution companies need to continuously monitor and improve the reliability indices of their systems. The network reconfiguration (NR) of a distribution system is a technique ...

Several constrained and unconstrained optimization problems have been adequately solved over the years thanks to advances in the metaheuristics area. in the last decades, different metaheuristics have been proposed employing ...

This paper introduces an improved Differential Evolution algorithm (IDE) which aims at improving its performance in estimating the relevant parameters for metabolic pathway data to simulate glycolysis pathway for yeast. ...

Unsupervised models can provide supplementary soft constraints to help classify new data since similar instances are more likely to share the same class label. In this context, this paper reports on a study on how to make ...

Over the the years, several metaheuristics have been developed to solve hard constrained and unconstrained optimization problems. in general, a metaheuristic is proposed and following researches are made to improve the ...

In this paper, the use of differential evolution ( DE), a global search technique inspired by evolutionary theory, to find the parameters that are required to achieve optimum dynamic response of parallel operation of ...
