Item EmbargoCombining state detection with knowledge transfer for constrained multi-objective optimization(IEEE, 0202-04-18) Zheng, Jinhua; Yang, Kaixi; Zou, Juan; Yang, ShengxiangThe main challenge in studying constrained multi-objective optimization problems (CMOPs) is reasonably balancing convergence, diversity, and feasibility. One of the most successful solutions to this challenge is the co-evolutionary frame-work, an algorithm in which multiple populations cooperate and complement each other, with different but interdependent populations addressing different but related problems. However, the effectiveness of existing algorithms for information exchange between various populations is not apparent. This paper proposes a new algorithm named SDKT using population state detection and knowledge transfer. The method has dual stages (i.e., knowledge acquisition and knowledge reception) and dual populations. Specifically, by restarting the strategy, these two populations (i.e., mainPop and auxPop) first explore more feasible regions with and without constraints. Then, in the knowledge receiving stage, ma i nPop and auxPop provide effective information to promote each other's approach to constrained PF (CPF) and unconstrained PF (UPF), respectively. Extensive experiments on three well-known test suites and three real-world problem studies fully demonstrate that SDKT is more competitive than five state-of-the-art constrained multi-objective evolutionary algorithms.

Item Open AccessA modular solution to the design of dedicated laboratory equipment(Sira Ltd, 1980-03) Goodyer, E. N.Microprocessor based instrumentation can be placed in two groups: either the instrument is intended for mass production, or its one of a small production batch of between 1 and 100 units. The project planning of the development of any microprocessor-based instrument is primarily determined by the category to which the final product belongs. Item Open AccessIntegration and testing of microprocessor based systems.(Sira-WSL (Warren Springs Laboratories), 1980-04) Goodyer, E. N.The process of integration is the combining of the independently tested software and hardware modules to produce a prototype system. Invariably the integrated system does not work, precipitating the pointed index finger phase of design procedure whereby the hardware and software engineers simultaneously raise their index figures to each other and exclaim "It is your fault". - they are course both correct. Item Open AccessA Microprocessor Gas Flow Computer(IMEKO - Institute of Measurement and Control, International Measurement Confederation, International Federation of Automatic Control, 1980-11) Goodyer, E. N.This presentation discusses some of the problems in accurate measurement of the flow rate of hydrocarbon gas; briefly reviews the limitations of analogue solutions; and finally presents a viable solution that employs a microprocessor-based gas flow computer.
