“…Despite the fact that largescale optimization has attracted much attention in singleobjective optimization [35]- [37], little work has been reported on large-scale multi-and many-objective optimization with few exceptions [38]- [40].

Abstract-The interests in multi-and many-objective optimization have been rapidly increasing in the evolutionary computation community. However, most studies on multi-and many-objective optimization are limited to small-scale problems, despite the fact that many real-world multi-and many-objective optimization problems may involve a large number of decision variables. As has been evident in the history of evolutionary optimization, the development of evolutionary algorithms for solving a particular type of optimization problems has undergone a co-evolution with the development of test problems. To promote the research on large-scale multi-and many-objective optimization, we propose a set of generic test problems based on design principles widely used in the literature of multi-and many-objective optimization. In order for the test problems to be able to reflect challenges in real-world applications, we consider mixed separability between decision variables and non-uniform correlation between decision variables and objective functions. To assess the proposed test problems, six representative evolutionary multi-and manyobjective evolutionary algorithms are tested on the proposed test problems. Our empirical results indicate that although the compared algorithms exhibit slightly different capabilities in dealing with the challenges in the test problems, none of them are able to efficiently solve these optimization problems, calling for the need for developing new evolutionary algorithms dedicated to large-scale multi-and many-objective optimization.

According to the definition of large-scale problems [24], the scale of a TPC model is influenced by (1) the size of a target industrial indoor environment (which is linked to the number of APs), (2) the grid size (gs), (3) the number of dominant obstacles, and (4) .  The first factor determines the dimensionality of a search space and impacts the complexity of fitness evaluation.…”

The industrial wireless local area network (IWLAN) is increasingly dense, due to not only the penetration of wireless applications to shop floors and warehouses, but also the rising need of redundancy for robust wireless coverage. Instead of simply powering on all access points (APs), it becomes an unavoidable challenge to dynamically control the transmit power of APs on a large scale, in order to minimize interference and adapt the coverage to the latest shadowing effects of dominant obstacles in an industrial indoor environment. To tackle this challenge, this paper formulates a transmit power control (TPC) model that enables both powering on/off APs and transmit power calibration of each AP that is powered on. This TPC model uses an empirical one-slope path loss model considering three-dimensional obstacle shadowing effects, to enable accurate yet simple coverage prediction. An efficient genetic algorithm (GA), named GATPC, is designed to solve this TPC model even on a large scale. To this end, it leverages repair mechanism-based population initialization, crossover and mutation, parallelism as well as dedicated speedup measures. The GATPC was experimentally validated in a small-scale IWLAN that is deployed a real industrial indoor environment. It was further numerically demonstrated and benchmarked on both small-and large-scales, regarding the effectiveness and the scalability of TPC. Moreover, sensitivity analysis was performed to reveal the produced interference and the qualification rate of GATPC according to varying target coverage percentage as well as number and placement direction of dominant obstacles.
