This paper presents a new multi-objective artificial bee colony algorithm called dMOABC by dividing the whole searching space S into two independent parts S1 and S2. In this algorithm, two "basic" colonies are assigned to search potential solutions in regions S1 and S2, while the so-called "synthetic" colony explores in S. This multi-colony model could enable the good diversity of the population, and three colonies share information in a special way. A fixed-size external archive is used to store the non-dominated solutions found so far. The diversity over the archived solutions is controlled by utilizing a self-adaptive grid. For basic colonies, neighbor information is used to generate new food sources. For the synthetic colony, besides neighbor information, the global best food source gbest selected from the archive, is also adopted to guide the flying trajectory of both employed and onlooker bees. The scout bees are used to get rid of food sources with poor qualities. The proposed algorithm is evaluated on a set of unconstrained multi-objective test problems taken from CEC09, and is compared with 11 other state-of-the-art multi-objective algorithms by applying Friedman test in terms of four indicators: HV, SPREAD, EPSILON and IGD. It is shown by the test results that our algorithm significantly surpasses its competitors. © 2014 Springer Science+Business Media New York.

In this paper, we suggest a new multi-objective artificial bee colony (ABC) algorithm by introducing an elitism strategy. The algorithm uses a fixed-size archive that is maintained based on crowding-distance to store non-dominated solutions found during the search process. In the proposed algorithm, an improved artificial bee colony algorithm with an elitism strategy is adopted for the purpose of avoiding premature convergence. Specifically, the elites in the archive are selected and used to generate new food sources in both employed and onlooker bee phases in each cycle. To keep diversity, a member located at the most crowded region will be removed when the archive overflows. The algorithm is very easy to be implemented and it employs only a few control parameters. The proposed algorithm is tested on a wide range of multi-objective problems, and compared with other state-of-the-art algorithms in terms of often-used quality indicators with the help of a nonparametric test. It is revealed by the test procedure that the algorithm produces better or comparable results when compared with other well-known algorithms, and it can be used as a promising alternative tool to solve multi-objective problems with the advantage of being simple and effective. © 2015 Elsevier B.V.

The design of class in the different layer is one of the most important works in software development based on three-tier architecture, however, the methods of component are the core of class and the characters of the function (component method) in different layer are different so to find out these characters and to form the design strategy of component method called function in this paper is very necessary. This paper gives not only the design strategy of function parameter but also the design strategy of function return value through the analysis of examples based on three-tier architecture. These conclusions provide an important guide for the detail design of component method in three-tier architecture. © 2015 IEEE.

The Artificial Bee Colony (ABC) algorithm is one of the most recent swarm intelligence based algorithms which simulates the foraging behavior of honey bee colonies. In this work, a particle swarm inspired multi-elitist ABC algorithm named PS-MEABC is proposed and applied for real-parameter optimization. In this modified version, the global best solution and an elitist randomly selected from the elitist archive are used to modify parameters of each food source in either onlooker bees or employed bees phases. PS-MEABC is compared with 5 state-of-the-art swarm based algorithms on CEC05 and BBOB12 benchmark functions in terms of four metrics: the mean error, the best error, the success rate (SR) and the expected running time (ERT). Wilcoxon signed ranks test results on the mean and the best error show that the performance of PS-MEABC is significantly better than or at least similar to these algorithms, and PS-MEABC has wider application range in terms of the success rate and faster convergence speed in terms of the expected running time. Our algorithm is comparable to its competitors with a fewer control parameters to be tuned. © 2013 Springer Science+Business Media New York.

This paper proposes a novel quantum-behaved particle swarm optimization (QPSO) algorithm with the global best (gbset) position subjected to Lévy probability distribution. Firstly, a Gaussian mutation with the mean being the gbest position and the standard deviation being half of the distance between the mean best (mbest) position and gbest position is executed on gbest position, hence, a GGQPSO algorithm is formed. On the basis of it, by selecting a fast and accurate Lévy random numbers numerical simulation algorithm and defining the 'effective standard deviation', the only 2 parameters of Lévy distribution can be determined according to empirical equations and trials respectively. Therefore, LGQPSO is taken shape. The distributions of gbest positions in LGQPSO, GGQP-SO and QPSO are compared with each other. For the purpose of verifying the effectiveness of LGQPSO, QPSO algorithm with Cauchy mutated gbest position is introduced. The above four algorithms are tested on 5 test functions. It is shown by the experiment results that LGQPSO is an approach that could considerably improve performances of QPSO. LGQPSO is more likely to escape from local optimum and obtain steadier solutions in most cases. © 2013 IEEE.

UML activity diagram is an important component of software design model based on UML, because it describes the dynamic behaviors of a software system. It becomes a valuable information source in software integration test. We present a workflow modeling method based on the improved UML acting diagram after introducing the UML language in this paper. The modeling for checking is described and analyzed. The result shows that the improved method can achieve better effect in describing workflow modeling progress than conventional approaches. Hence it provides an approach to model checking UML AD s by model-checker FDR. Finally, the formalisms and model checking are explicitly illustrated through a simple but non-trivial example.© 2010 IEEE.
