In this paper, a hybridization model based on culture algorithm and Artificial Bee Colony is proposed. The objective of the hybrid model is mainly to get benefit of the previous knowledge gained by predecessor foragers which help bees searching for food sources in potential positions. The proposed CB-ABC focuses on the kind of information in the belief space that should be stored to reduce promising solutions’ area. Moreover, CB-ABC divides the population into two groups of individuals, one group updates by the heritage of best previous solutions and the other group updates by self-adaptive information. The performance of the new algorithm has been validated on a variety of numerical testbench functions (ranging from CEC 2005 and CEC 2017) and compared to standard ABC and other variants named ABCM, HPA and CABCA as well.The proposed algorithm proves its success as well when applied on Wireless Sensor Network (WSN) to locate them accurately. To validate the performance of CB-ABC it is compared with Particle Swarm Optimization (PSO), Genetic Algorithm (GA), Cuckoo Search (CS), Firefly Algorithm (FA) and Parallel Firefly Algorithm (PFA). CB-ABC shows the least average error value compared to the standard ABC as well as the other algorithms previously mentioned in the comparison. Moreover, CB-ABC succeeds in reducing the number of iterations as well as function evaluations to 17% of those of the standard ABC to 20% of those obtained by ABCM during solving WSN localization problem. CB-ABC’s parametric study (heritage size and offspring ratio) has been carried out as well. 相似文献

In this paper, we introduce a novel iterative method to finding the fixed point of a nonlinear function. Therefore, we combine ideas proposed in Artificial Bee Colony algorithm (Karaboga and Basturk, 2007) and Bisection method (Burden and Douglas, 1985). This method is new and very efficient for solving a non-linear equation. We illustrate this method with four benchmark functions and compare results with others methods, such as ABC, PSO, GA and Firefly algorithms. 相似文献

In this study, diagnosis of diabetes disease, which is one of the most important diseases, is conducted with artificial intelligence techniques. We have proposed a novel Artificial Bee Colony (ABC) algorithm in which a mutation operator is added to an Artificial Bee Colony for improving its performance. When the current best solution cannot be updated, a blended crossover operator (BLX-α) of genetic algorithm is applied, in order to enhance the diversity of ABC, without compromising with the solution quality. This modified version of ABC is used as a new tool to create and optimize automatically the membership functions and rules base directly from data. We take the diabetes dataset used in our work from the UCI machine learning repository. The performances of the proposed method are evaluated through classification rate, sensitivity and specificity values using 10-fold cross-validation method. The obtained classification rate of our method is 84.21% and it is very promising when compared with the previous research in the literature for the same problem. 相似文献

人工蜂群算法在多峰高维函数优化问题的求解上取得了较好的结果,但随着函数的复杂度及维数增高,仍存在收敛速度慢、易陷入局部最优等问题。为此,提出一种新的人工蜂群算法。将人工蜂群对食物源的单维贪婪搜索改进为多维贪婪搜索以增强蜂群的搜索能力,避免在个别维度上出现较优解的食物源由于达到更新阈值却被废弃而造成迂回搜索的现象,引入扰动搜索机制避免迭代后期食物源位置在个别维度收敛导致算法陷入局部最优。仿真实验结果表明,该算法能保持深度挖掘和广度搜索上的平衡,在高维函数优化问题求解的收敛速度和计算精度方面表现出较好的性能。 相似文献

In this paper, a new hybrid learning algorithm is introduced to evolve the flexible beta basis function neural tree (FBBFNT). The structure is developed using the Extended Genetic Programming (EGP) and the Beta parameters and connected weights are optimized by the Hybrid Artificial Bee Colony algorithm. This hybridization is essentially based on replacing the random Artificial Bee Colony (ABC) position with the guided Opposite-based Particle Swarm Optimization (OPSO) position. Such modification can minimize the delay which might be lead by the random position, in reaching the global solution. The performance of the proposed model is evaluated for benchmark problems drawn from time series prediction area and is compared with those of related methods. 相似文献

This article focuses on the application of nature-inspired optimization algorithm for adaptive speed control of permanent synchronous motor (PMSM) drive with variable parameters. In the proposed approach, a state feedback controller (SFC) is utilized for speed control of the PMSM, while on-line adaptation of its coefficients is made with the help of Artificial Bee Colony (ABC) algorithm. Since ABC is the first time applied for adaptation of SFC, its necessary modifications are depicted with details. In order to assure stability and robustness of the considered control scheme, a linear–quadratic optimization method is employed during adaptation. To ensure repeatable response of the plant regardless of parameter’s variation, a model reference adaptive system (MRAS) is used. The proposed approach is examined in simulation and experimental studies, including variable moment of inertia, non-measurable load torque and unmodelled friction. These confirm that adaptive SFC based on ABC noticeably improves control performance in comparison to a non-adaptive one. 相似文献
