<https://discovery.ucl.ac.uk/id/eprint/10129908> <http://purl.org/ontology/bibo/abstract> "Non-Dominated Sorting Genetic Algorithm (NSGA-II) is one of the\r\nmost popular Multi-Objective Evolutionary Algorithms (MOEA)\r\nand has been applied to a large range of problems.\r\nPrevious studies have shown that parameter tuning can improve\r\nNSGA-II performance. However, the tuning of the offspring population size, which guides the exploration-exploitation trade-off in\r\nNSGA-II, has been overlooked so far. Previous work has generally\r\nused the population size as the default offspring population size for\r\nNSGA-II.\r\nWe therefore investigate the impact of offspring population size\r\non the performance of NSGA-II. We carry out an empirical study by\r\ncomparing the effectiveness of three configurations vs. the default\r\nNSGA-II configuration on six optimization problems based on four\r\nPareto front quality indicators and statistical tests.\r\nOur findings show that the performance of NSGA-II can be improved by reducing the offspring population size and in turn increasing the number of generations. This leads to similar or statistically\r\nsignificant better results than those obtained by using the default\r\nNSGA-II configuration in 92% of the experiments performed."^^<http://www.w3.org/2001/XMLSchema#string> .
