The CLONALG is a combinatorial optimization technique inspired by biological immune systems, which aims at reproducing the main properties and functions of the system. The SGACB is an optimization algorithm inspired by natural selection and the evolution of species. The reconfiguration problem with variable demands is a complex combinatorial problem that aims at identifying the best radial topology for an EDS, while satisfying all technical constraints at every demand level and minimizing the cost of energy losses in a given operation period. Both algorithms were implemented in C++ and test systems with 33, 84, and 136 nodes, as well as a real system with 417 nodes, in order to validate the proposed methods. The obtained results were compared with results available in the literature in order to verify the efficiency of the proposed approaches.689-701engArtificial immune systemsClonal selection algorithmDistribution systems reconfigurationMetaheuristicsSpecialized genetic algorithm of Chu–BeasleyVariable demandsArtigo10.1007/s40313-016-0268-9Acesso aberto2-s2.0-849939718672-s2.0-84993971867.pdf
