Improved artificial bee colony algorithm based on escaped foraging strategy

This paper presents an improved artificial bee colony algorithm. Under the framework of the basic artificial bee colony algorithm, this paper redefines the artificial bee colony and introduces search strategies for group escape and foraging based on Levy flight. The proposed algorithm is named artificial bee colony algorithm based on escaped foraging strategy (EFSABC).There are different strategies for scout bees, onlookers, and free bees searching for honey sources in the EFSABC: all working bees relinquish old honey sources due to disturbance, and select different routines to seek new honey sources. Sixteen typical high-dimensional standard functions are used to verify the effectiveness of the proposed algorithm. The EFSABC algorithm outperforms the traditional artificial bee colony algorithm in all aspects.     

A hybrid artificial bee colony algorithm for flexible job shop scheduling with worker flexibility

The traditional flexible job shop scheduling problem (FJSP) considers machine flexibility but not worker flexibility. Given the influence and potential of human factors in improving production efficiency and decreasing the cost in practical production systems, we propose a mathematical model of an extended FJSP with worker flexibility (FJSPW). A hybrid artificial bee colony algorithm (HABCA) is presented to solve the proposed FJSPW. For the HABCA, effective encoding, decoding, crossover and mutation operators are designed, and a new effective local search method is developed to improve the speed and exploitation ability of the algorithm. The Taguchi method of Design of Experiments is used to obtain the best combination of key parameters of the HABCA. Extensive computational experiments carried out to compare the HABCA with some well-performing algorithms from the literature confirm that the proposed HABCA is more effective than these algorithms, especially on large-scale FJSPW instances.

改进克里金插值算法的井下无线定位指纹库构建方法

针对煤矿井下巷道中构建一个采集点密集分布的无线定位指纹库,需要逐点采集信号,会耗费大量的人力和时间,为此提出基于模拟退火SA(Simulated Annealing)人工蜂群ABC(Artificial Bee Colony)混合算法优化克里金(Kriging)插值算法的构建井下无线定位指纹库的方法。首先通过无线网络采集井下巷道部分采集点的指纹数据,并建立采集指纹数据库。其次利用采集指纹数据库构建Kriging插值算法模型,再通过SA-ABC算法对变异函数的参数寻优,建立SA-ABC-Kriging插值算法模型。再次用插值算法估算出预测点的信息数据,并建立插值指纹数据库。最后将采集指纹数据库和插值指纹数据库构建井下无线定位指纹库。实验表明,该构建方法比传统Kriging插值算法的定位精度和插值精度更高,而且可减少50%的人工采集指纹数据工作量。     

A decomposition-based many-objective artificial bee colony algorithm with reinforcement learning

When optimizing many-objective optimization problems (MaOPs), the optimization effect is normally related to the problem types. Therefore, enhancing the generalization ability is essential to the application of the algorithms. In this paper, a novel decomposition-based Artificial bee colony algorithm (ABC) for MaOP optimization, MaOABC/D-LA, is presented to enhance the generalization ability. A reinforcement learning-based searching strategy is designed in the MaOABC/D-LA, with which the algorithm adjusts its searching actions according to their performance. And a variant of the onlooker bee mechanism is proposed to balance the optimization quality. To investigate performance of the proposed algorithm, a comparison experiment is conducted. The experimental results show that the MaOABC/D-LA outperforms the peer algorithms in efficiency and solution quality for MaOPs with different types of features. This indicates the proposed method has a definite effect on improving generalization ability.
