Inspired by artificial bee colony algorithm (ABC), which is widely employed in various kinds of aspects. However, there is a lack of research on source seeking problem through ABC algorithm. This paper proposes a strategy which utilizes a swarm of robots to accomplish autonomous mutilple-source localization. The location method for the strategy is based on a kind of population based stochastic optimization algorithm which is called artificial bee colony algorithm (ABC). We do simulation experiments to get the most suitable parameters of the ABC algorithm according to the time and the error between each optimal solution and the source point. This strategy will minimize the overall error and maintain a shorter run time. In the future, our strategy will be utilizing in real environment, and will be employed on many kinds of different flied.

Fractional-order calculus with special memorability could describe dynamic characteristics of the object more accurately, and the establishment of fractional-order mathematical model can provide more convenience for tuning the parameters of PIλDμ controller. Fractional-order transfer functions can completely represent characteristics of thermal process compared with the integral-order ones applied in coal-fired power plant, such as strong coupling, disturbance factors, huge difference between response speed, etc. Aiming at the characteristics of multiple parameters for fractional-order transfer function model, two promising approaches are proposed. Firstly, an improved artificial bee colony algorithm, based on Lévy flights strategy, is introduced in optimizing the parameters of nominal model. Secondly, objective(fitness) function with penalty factor is developed to obtain the static gain of model. Finally, it is attempted to apply the proposed identification method, based on fractional-order transfer function model, to a circulating fluidized bed(CFB) superheater in an in-service power unit. The field data identification well demonstrates the virtues of improved identification method and indicates promising prospects for fractional-order transfer function model in thermal process of power plant.

In optimization of multiple tuned mass dampers (MTMDs), certain restrictions or preconditions such as uniform distribution of stiffness, mass, or frequency spacing had been applied for simplification, but in turn, solution of individual stiffness and damping parameters are not the true optima. The main purpose of this paper is to obtain the true optima of individual stiffness and damping parameters of MTMD system. In the proposed method, parameters of TMD units are treated as free search optimization variables, and an efficient optimization algorithm, namely, artificial bee colony algorithm has been utilized in obtaining optimum parameters of MTMDs. Performance proposed method with respect to uncontrolled structure is verified through numerical analyses and compared with other reported methods. Comparisons show a superior performance of proposed approach. The basic properties of optimum design, the effectiveness, and robustness with respect to number of dampers are also discussed.

Creating appropriate colour schemes is challenging for both novice and experienced cartographers. This paper introduces an artificialbeecolony (ABC) algorithm to automatically create various colour schemes. Colour scheme creation is treated as a constrained search problem in a continuous colour space. We considered the gamut of the target device and a series of cartographic rules, such as convention, discrimination, contrast, perceptual uniformity and brightness mirror, in the ABC algorithm and presented detailed initialization, fitness definition, local exploration, and global exploration methods for creating qualitative, sequential and diverging colour schemes. The proposed method is evaluated with a case study, and the results indicate that compared with the brute force search method, the proposed method can create satisfying colour schemes of similar quality but significantly improved efficiency.

artificialbeecolony (ABC) is a simple and powerful optimisation algorithm, which simulates the random behaviour of honey bees. In this study, a modified version of ABC algorithm is proposed by considering: 1) initialising the population based on chaos theory;2) utilising multiple searches, instead of single search, in employee and onlooker bee phases;3) controlling the frequency of perturbation by a modification rate. The proposed algorithm implemented by C# programming language and executed on benchmark functions of Sphere, Rosenbrock, Rastrigin, non-continuous Rastrigin, Griewank, Schwefel, Schwefel 1.2, Schwefel 2.2, Step and Ackley. The performance of proposed ABC algorithm is compared with ABC and modified ABC algorithms, on different tests, according to measures of mean and standard deviation. Findings showed the suggested algorithm outperforms ABC and modified ABC algorithms in 65% of test cases in getting best mean and in 55% of cases for standard deviation.

In this study, a dual-wideband monopole antenna has been designed and developed for the universal mobile telecommunications system (UMTS), wireless local area network (WLAN), and worldwide interoperability for microwave access (WiMAX) applications. A novel approach integrating artificialbeecolony (ABC) with the HyperLynx (R) 3D electromagnetic platform based on the method of moments has been employed to calculate the design parameters of the monopole antenna performance for the respective target frequencies and return loss. The proposed dual-wideband antenna operates in the dual-frequency ranges of 1.69-3.99 and 4.75-6.22 GHz applicable for the UMTS, WLAN, and WiMAX applications and it is fabricated on the flame resistant-4 substrate plate of 42 x 51 x 1.6 mm(3). The performance of the presented monopole antenna is analyzed in terms of gain, radiation pattern, and s-parameter. The input reflection coefficient (S-11) parameter and radiation pattern of the antenna are verified through the measurements. The measured values of the antenna parameters are found to match well within tolerable limits with the simulation results. The results illustrate that the presented dual-wideband monopole antenna obtained by using the ABC algorithm exhibits better performance in point of operating bands and s-parameter as compared with the multi-band antennas previously published in the literature.

This paper focuses on the issue of the large calculation when searching for the optimal solution of weighted subspace fitting algorithm (WSF) in the Direction of Arrival (DOA) estimation and introduces the artificial bee colony algorithm (ABC) to optimize solving process. Taking advantage of Niche technique and coordinating with improved strategy and control exclusion method, the proposed algorithm can overcome the weakness that beecolonyalgorithm itself can only get the global solutions, and hence get the local optimization solution for the multimodal problem. The experiment results demonstrate the proposed algorithm has small computation load, less controlling parameters, and high accuracy.

In this study, the artificialbeecolony (ABC) algorithm was developed to solve the Chenderoh Reservoir operation optimisation problem which located in the state of Perak, Malaysia. The proposed algorithm aimed to minimise the water deficit in the operating system and examine its performance impact based on monthly and weekly data input. Due to its capability to identify different possible events occurring in the reservoir, the ABC algorithm provides promising and comparable solutions for optimum release curves. The optimal release curves were then used to stimulate the reservoir release under different operating times under different inflow scenarios. To investigate the performance of both the monthly and weekly ABC optimisation employed in the reservoir, the well-known reliability, resilience and vulnerability indices were used for performance assessment. The indices tests revealed that weekly ABC optimisation outperformed in terms of reliability and vulnerability leading to the development of a better release policy for optimal operation.

This paper proposes a hybrid artificial bee colony algorithm for the cooperative maximum covering location problem (CMCLP) on a network. In location covering problems, it is assumed that each facility generates a signal whose strength decreases with the increase in distance and a demand point is considered to be covered if the total signal strength received by it from various facilities exceeds a certain threshold. The objective of the CMCLP is to locate the facilities in such a way that maximizes the total demands covered. The proposed hybrid approach obtained better quality solutions in comparison to the methods available in the literature.
