Performance optimization of an antenna is a non-linear, multi-dimensional and complex scheme, which can be solved by applying intelligence algorithms. A Quasi-Opposition grey wolf optimization (QOGWO) algorithm is presented to improve the grey wolf optimization (GWO) algorithm. It is prone to global optimality, high precision for complex problems and a fast convergence rate at a later stage. A wideband dual-polarized magneto-electric dipole antenna is simulated as an example. Compared to the GWO algorithm, the antenna optimized by the improved algorithm has a wider bandwidth, verifying the feasibility of the algorithm in the field of antenna design optimization.

Recently, nature inspired algorithms (NIA) have been implemented to various fields of optimization problem such as biomedical engineering, electrical engineering, computer science and etc. The achievement of NIA in solving optimization in these fields becoming the motivation to apply one of the NIA namely grey wolf Optimizer (GWO) into overcurrent relay coordination problem. However, the current state of GWO suffers lack of exploration problem. Hence, the improvement of GWO has been proposed in this paper to enhance the exploration of original GWO. The improvement of GWO (IGWO) is implemented in finding the the optimal value of the Time Multiplier Setting (TMS) and Plug Setting (PS) in order to minimize the primary relays' operating time at the near end fault. Comprehensive simulation studies have been performed to demonstrate the reliability and efficiency of the proposed modification technique compared to the original GWO. The generated results have confirmed the proposed IGWO is able to improve the objective function of the overcurrent relay coordination problem.

Non-intrusive load monitoring is important for the development of smart grids. In order to get the load status and power consumption information of each device, single classifiers such as the support vector machines, the MLP neural networks and the extreme learning machines are widely used to identify the appliances. But the single classifiers are faced with the risk of local optimum and overfitting. In order to improve the recognition accuracy of the single classic classifiers, a hybrid identification model based on grey wolf optimization algorithm is proposed in this paper. The experimental results based on the actual measured data verified that the recognition accuracy of the proposed method is significantly higher than that of the single classical classification models.

There are many adjustable parameters in the control method of predictive sliding mode control(PSMC) law and linear extended state observer(LESO) for hypersonic vehicle speed and altitude,and the adjustable parameters influence each other on the control effect,and the speed and altitude channels of the aircraft are coupled with each other,so the controller parameters cannot be independently tuned.A method of automatically tuning controller parameters by using grey wolf optimization(GWO) algorithm is ***,the fitness function containing the desired control effect is designed,and then the appropriate number of search agent and iteration times are *** simulation results show that the control effect of the controller with GWO tuning parameters is obviously better than that of the controller with experience tuning parameters,and the expected control effect can be achieved under the condition of adding parameter deviation and actuator limitation.

The key to wireless sensor network coverage lies in how to achieve full coverage of the region with as few sensor nodes as possible. The research on wireless sensor network coverage often faces problems such as low optimization accuracy, slow convergence speed, and susceptibility to premature convergence. To address these issues, A multi strategy network coverage grey wolf optimization algorithm (MSGWO) based on roulette wheel is proposed. Firstly, a mixed mapping of Tent and Circle maps is used to map the initial distribution of wireless sensor nodes, so that the initial distribution of sensor nodes is as evenly distributed as possible in the space. Secondly, as the iteration cycle changes, multi strategy position updates are performed on the gray wolves that meet the conditions in the grey wolf optimization algorithm (GWO) to improve the ability to jump out of local convergence. Finally, in the iterative optimization of the grey wolf optimization algorithm, a leadership strategy based on the roulette wheel method was used to expand the global search range of the algorithm. Simulation experiments have shown that MSGWO has higher coverage and less time consumption.

This paper proposed the adaptive elitism-based immigration to improve the grey wolf optimization performance. The concept of elitism-based immigration is to generated immigrants and replaces it to the worst individuals in the population. The elite immigrants in our proposed are mutated before replace to the worst individuals and the parameter to control mutation ratio and elite immigrants ratio are adaptive. The performances have been evaluated by using 7 well-known benchmark functions and compared with the traditional grey wolf optimizer (GWO) algorithm, particle swarm optimization (PSO) and differential evolution (DE) algorithm. The experimental results showed that the proposed algorithm has ability to solving optimization problems.

this work presents a control technique for Mobile Robot Navigation using augmented reality (AR). This navigation technique is based on optimized Fuzzy Cognitive Map (FCM) and AR's Glyphs. AR's symbols are provided by the overhead camera. The patterns are made up of glyphs and a clear path. Six practical test are manipulated to examine the strength of optimizing FCM by a mobile robot for navigation with AR's symbols. The experiment examined the effectiveness of a grey wolf optimization algorithm (GWOA) in optimizing the FCM. Two practical experiments confirm that AR's Glyphs are an effective symbol for a robot to navigation in an unknown environment. A practical experiment reveals that a robot can use AR to manage its intended movement. Augmented reality, such as the Glyphs and a simplified map, are an effective tool for mobile robots to use in navigation in unknown environments. A prototype system is made to navigate the mobile robot by using AR and FCM.

The optimization of the multi-energy storage configuration within the Integrated Energy System (IES) is achieved through the utilization of an Improved grey wolf optimization algorithm (IGWO), which enhances economic efficiency, reliability, and environmental sustainability. An IES model incorporating wind and photovoltaic generation along with various storage devices has been established, alongside the development of a multi-objective model focused on minimizing costs and emissions. The introduction of a Gaussian mutation strategy within the improved algorithm bolsters exploratory capabilities and enhances population diversity. Furthermore, an entropy-weight method has been employed to automatically determine the weights of evaluation criteria, ensuring the objectivity and rigor of decision-making. Validation through case studies has confirmed the method's effectiveness in enhancing the cost-efficiency and environmental performance of the IES, showcasing its capability to manage energy flows effectively, reduce costs, and minimize environmental impacts while maintaining system performance. © 2024 IEEE.
