Optimizing real-life engineering design problems are challenging and somewhat difficult if optimum solutions are expected. The development of new efficient optimization algorithms is crucial for this task. In this paper, a recently invented grasshopper optimization algorithm is upgraded from its original version. The method is improved by adding an elite opposition-based learning methodology to an elite opposition-based learning grasshopper optimization algorithm. The new optimizer, which is elite opposition-based learning grasshopper optimization method (EOBL-GOA), is validated with several engineering design probles such as a welded beam design problem, car side crash problem, multiple clutch disc problem, hydrostatic thrust bearing problem, three-bar truss, and cantilever beam problem, and finally used for the optimization of a suspension arm of the vehicles. The optimum results reveal that the EOBL-GOA is among the best algorithms reported in the literature.

Feature selection is the problem of finding the minimum number of features among a redundant feature space which leads to the maximum classification performance. In this paper, we have proposed a novel feature selection method based on mathematical model of interaction between grasshoppers in finding food sources. Some modifications were applied to the grasshopper optimization algorithm (GOA) to make it suitable for a feature selection problem. The method, abbreviated as GOFS is supplemented by statistical measures during iterations to replace the duplicate features with the most promising features. Several publicly available datasets with various dimensionalities, number of instances, and target classes were considered to evaluate the performance of the GOFS algorithm. The results of implementing twelve well-known and recent feature selection methods were presented and compared with GOFS algorithm. Comparative experiments indicate the significance of the proposed method in comparison with other feature selection methods. (C) 2018 Elsevier Ltd. All rights reserved.

With the increasing number of electricity consumers, production, distribution, and consumption problems of produced energy have appeared. This paper proposed an optimization method to reduce the peak demand using smart grid capabilities. In the proposed method, a hybrid grasshopper optimization algorithm (GOA) with the self-adaptive Differential Evolution (DE) is used, called HGOA. The proposed method takes advantage of the global and local search strategies from Differential Evolution and grasshopper optimization algorithm. Experimental results are applied in two scenarios;the first scenario has universal inputs and several appliances. The second scenario has an expanded number of appliances. The results showed that the proposed method (HGOA) got better power scheduling arrangements and better performance than other comparative algorithms using the classical benchmark functions. Moreover, according to the computational time, it runs in constant execution time as the population is increased. The proposed method got 0.26 % enhancement compared to the other methods. Finally, we found that the proposed HGOA always got better results than the original method in the worst cases and the best cases.

Due to the proliferation of sophisticated cyber extortion with exponentially critical effects, intrusion detection system is being evolved systematically their revealing, understanding, attribution and mitigation capabilities. Unfortunately, most of the modern Intrusion Detection System (IDS) technique does not provide sufficient defense services in the wireless environment while maintaining operational continuity and the stability of the defense objective in the presence of intruders and modern attacks. To resolve this problem, we propose a new feature selection technique by combining Ensemble of Feature Selection (EFS) and Chaotic Adaptive grasshopper optimization algorithm (CAGOA) method, called ECAGOA. The proposed method has the capability of preventing stagnation issue and is particularly credited to the following three aspects. Firstly, EFS method is applied for selecting the high ranked subset of attributes. Then, we have employed chaos concept in grasshopper optimization algorithm (GOA) which generates a uniformly distributed population to enhance the quality of the initial populations and has the capability to manage two different issues such as the ability to search for new space termed as exploration and the ability to use existing space termed as exploitation in the optimization process. In order to avoid local optima and premature convergence, lastly, an adaptive grasshopper optimization algorithm is developed by using organized parameter adaptation method. Furthermore, the adaptive behavior of GOA is applied to decide whether a record signifies an anomaly or not, differing from some approaches acquainted in the literature. Support vector machine (SVM) is used as a fitness function in the proposed method to choose the relevant features that can help classify the attacks accurately. In addition, it is also applied to optimize the penalty factor (C), kernel parameter (sigma), and tube size (epsilon) of SVM method. The proposed algorithm is evaluated usin

Discharge for wastewater treatment plays a key role in improving the water quality, thereby guaranteeing living quality of citizens. With high-speed economics growth and economics reforming, total amount of China's discharge of wastewater treatment is sharing high uncertainty, leading to many difficulties in accurate forecasts of discharge of wastewater treatment. Based on grey system theory, the hyperbolic time-delayed term is introduced in this paper to develop a novel forecasting model in order to deal with uncertainties of China's sewage discharge forecasting. The key nonlinear parameter of the proposed model is determined by the grasshopper optimization algorithm. A series of practical numerical cases prove that the proposed model is reliable in comparison with six existing models are used for comparison. Then we apply it to predict the behavior of sewage discharge in China, those results against demonstrating the model our proposed has more satisfactory prediction precision. (C) 2020 The Authors.

Recent technological advances in sensor networks show rapid growth in healthcare monitoring systems based on Wireless Body Area Networks (WBANs). A small sensor attached to the body can record various psychological parameters. WBAN sensors frequently fail due to noise, misalignment of the hardware, and patient perspiration. It is difficult for healthcare professionals to determine whether the data collected by these sensing devices is defected or influenced by a malicious attacker. Even inaccurate information can result in a wrong diagnosis, and the physiological parameters are categorized as normal or abnormal. This research focuses on reading anomaly detection for wireless body sensors and proposes a novel method based on hybrid machine-learning algorithms. A hybrid Artificial Neural Network - grasshopper optimization algorithm (ANN-GOA) is proposed to find anomalous records in the dataset. Each anomalous record's predicted value determines whether the recognized form is anomalous. The suggested hybrid ANN-GOA method results are compared with the parameters like recall, accuracy, F1 score, loss, and precision. The simulation results of the proposed hybrid ANN-GOA algorithm provide better accuracy of 98.8%, recall of 99.9%, F-score of 97.9% and precision of 99.8% when compared with other conventional algorithms.

grasshopper optimization algorithm (GOA) is a meta-heuristic algorithm for solving optimization problems by modeling the biological habit and social behavior of grasshopper swarms in nature. Compared with other optimization algorithms, GOA still has room to improve its performance on solving complex problems. Therefore, this paper proposes an improved grasshopper optimization algorithm (EMGOA) based on dynamic dual elite learning and sinusoidal mutation. First of all, dynamic elite learning strategy is adopted to improve the influence of elites on the update process, enabling the algorithm to have a faster convergence speed. Then, sinusoidal function is utilized to guide the mutation of the current global optimal individual during each iteration to avoid the algorithm falling into the local optimum and improve the convergence accuracy of the algorithm. In order to investigate the performance of the proposed EMGOA algorithm, experiments are conducted on 26 benchmark functions and CEC2019 in this paper. The experimental results show that the optimization performance of EMGOA is obviously better than GOA, and EMGOA is competitive with six state-of-the-art meta-heuristic optimization algorithms.

作者： Fathy, Ahmed Zagazig Univ Elect Power & Machine Dept Fac Engn Zagazig Egypt

When solar radiation striking the PV modules inserted in PV array is non-homogeneous;then the partial shading operation is taken place. This phenomenon has negative effects on the efficiency of the PV array as the generated power is reduced, hot spots are generated;one solution to get rid of these negatives is the reconfiguration of modules such that distributing the solar radiation in regular form as much as possible. Therefore, this paper proposed a new methodology based on recent meta-heuristic optimization algorithm named grasshopper to be applicable in solving the reconfiguration process of the partially shaded PV array optimally. The main purpose of such action is to maximize the power extracted from the array via proposed objective function presented in this work. The PV array arrangement obtained via the proposed approach incorporated recent meta-heuristic grasshopper optimization algorithm (GOA) is compared with those obtained via total cross tied connection (TCT), Su Do Ku connection and genetic algorithm (GA) configuration. Additionally, different shadow patterns during a day are studied and reconfiguration arrangement is obtained at each hour. The obtained results confirm the reliability and the efficiency of the proposed GOA in evaluating the global maximum power point (GMPP) extracted from the partially shaded PV array.

In metaheuristic multi-objective optimization, the term effectiveness is used to describe the performance of a metaheuristic algorithm in achieving two main goals-converging its solutions towards the Pareto front and ensuring these solutions are well-spread across the front. Achieving these objectives is particularly challenging in optimization problems with more than three objectives, known as many-objective optimization problems. Multi-objective algorithms often fall short in exerting adequate selection pressure towards the Pareto front in these scenarios and difficult to keep solutions evenly distributed, especially in cases with irregular Pareto fronts. In this study, the focus is on overcoming these challenges by developing an innovative and efficient a novel Many-Objective grasshopper Optimisation algorithm (MaOGOA). MaOGOA incorporates reference point, niche preserve and information feedback mechanism (IFM) for superior convergence and diversity. A comprehensive array of quality metrics is utilized to characterize the preferred attributes of Pareto Front approximations, focusing on convergence, uniformity and expansiveness diversity in terms of IGD, HV and RT metrics. It acknowledged that MaOGOA algorithm is efficient for many-objective optimization challenges. These findings confirm the approach effectiveness and competitive performance. The MaOGOA efficiency is thoroughly examined on WFG1-WFG9 benchmark problem with 5, 7 and 9 objectives and five real-world (RWMaOP1- RWMaOP5) problem, contrasting it with MaOSCA, MaOPSO, MOEA/DD, NSGA-III, KnEA, RvEA and GrEA algorithms. The findings demonstrate MaOGOA superior performance against these algorithms.
