Although differential evolution (DE) algorithms have shown great power in solving continuous optimization problems, it is still a challenging task to design an efficient binary variant of DE algorithm. In this paper, we propose a binary learning differential evolution (BLDE) algorithm, which can efficiently search the feasible region by learning from the(More)
In evolutionary multi-objective optimization (EMO), the convergence to the Pareto set of a multi-objective optimization problem (MOP) and the diversity of the final approximation of the Pareto front are two important issues. In the existing definitions and analyses of convergence in multi-objective evolutionary algorithms (MOEAs), convergence with(More)
This paper presents a virtual laboratory platform based on the B/S structure framework in distributed network, and the virtual laboratory platform includes the software and hardware resources. The virtual laboratory allows network terminal to access through the network. The two parts of the virtual laboratory are laboratory device interface platform and(More)
Surrogate-assisted evolutionary algorithms have been widely utilized in science and engineering fields, while rare theoretical results were reported on how surrogates influence the performances of evolutionary algorithms (EAs). This paper focuses on theoretical analysis of a (1+1) surrogate-assisted evolutionary algorithm ((1+1)SAEA), which consists of one(More)
A new method based on rough set theory to classify goods is put forward in this paper. Firstly, we set up a decision table of goods classification; secondly we get some certain rules from this decision table and get a new totally disharmonious decision table by deleting the objects, which can be identified by these certain rules; finally, we get the(More)
A real-time harmonic measuement system is presented in the paper. The system is combined by the ARM9 chip and virtual instrument technology. the paper set out the system's hardware structure diagram, harmonic analysis algorithm, the simulation result, and the LabVIEW subroutine which used to show the result. The wavelet packet transform is used to detect(More)
