Population size reduction for the differential evolution algorithmBrest, Janez (Avtor) Sepesy Maučec, Mirjam (Avtor) differential evolutioncontrol parameterfitness functionglobal function optimizationself-adaptationpopulation sizeThis paper studies the efficiency of a recently defined population-based direct global optimization method called Differential Evolution with self-adaptive control parameters. The original version uses fixed population size but a method for gradually reducing population size is proposed in this paper. It improves the efficiency and robustness of the algorithm and can be applied to any variant of a Differential Evolution algorithm. The proposed modification is tested on commonly used benchmark problems for unconstrained optimization and compared with other optimization methods such as Evolutionary Algorithms and Evolution Strategies.20082012-06-01 10:56:52Neznano27391UDK: 004.8COBISS_ID: 11642646ISSN pri članku: 0924-669XNUK URN: URN:SI:UM:DK:RPL9QBBLsl
