In this article, a new metaheuristic bioinspired technique oppositional artificial rabbit optimization (OARO) technique is enhanced and employed, for phasor measurement unit (PMU) placement in distribution system. Based on PMUs, this study emphasizes their advantages for real-time monitoring. Quite differently, the PMU serves as the system's cornerstone. The goal of this kind of technology is to analyse data quickly and automatically arrive at a decision. Four scenarios are taken into consideration in the simulation study for each test system, and the goal is to minimize costs while taking into account fewer PMU. The first case focuses primarily on the number of PMU set as the objective function;the second case uses the wide area monitoring system (WAMS) data traffic index and installation cost to observe comprehensive observability. The third case focuses on how many PMU are used in conjunction with zero injection bus (ZIB). Finally, ZIB and WAMS are implemented together to reduce data traffic and, eventually, the fitness function. There is artificial rabbit optimization (ARO), inspired by the survival of rabbits, such as detour foraging and random hiding. The behaviour of the rabbits in random searching for food in other region neglecting its own region followed by random hiding amongst all borrowings to reduce the chances for the predators to search them to kill. In this study, an oppositional strategy of rabbits' finding the tunnels is applied for finding the food search space. In addition, the rabbit energy shrink strategy is implemented to transmit rabbits from detour foraging and random hiding. The concept of oppositional-based learning applied to rabbit survival strategy has been mathematically modelled and tested in PMU placement problems in the radial distribution system. The methods are evaluated in radial distribution systems with 33, 69, 85, 118, and 141 buses. In each case, it is found that OARO provides better results on PMU placement for phasor measu

PurposeThis study aims to enhance stock price prediction accuracy by integrating a gated recurrent unit (GRU) with an artificial rabbit optimization (ARO) algorithm. The objective is to address the issues in hyperparameter optimization and deliver a high-performance predictive model for stock market trends tested on the Dow Jones Industrial Average (DJIA) ***/methodology/approachThe proposed ARO-GRU hybrid model uses a GRU for time-series stock price prediction and an ARO to dynamically optimize the model's parameters. ARO-GRU was benchmarked against various models, including single-layer and multi-layer GRU, BiLSTM and long short-term memory (LSTM) models optimized by genetic algorithms (GA) or ARO. Performance was assessed using metrics such as the mean square error (MSE), mean absolute error (MAE), mean absolute percentage error (MAPE) and R-squared (R2).FindingsThe experimental results showed that the ARO-GRU model significantly outperformed its counterparts. Compared to the best alternative model (LSTM-ARO), ARO-GRU reduced the MSE by 81.8% (from 22.731 to 1.864 for the AAPL stock) and the MAPE by 64% (from 0.025 to 0.009). It achieved an average R2 score improvement of 5.3% across all tested stocks, demonstrating a better model fit. In addition, the ARO-GRU model required 83% less computational time than the LSTM-ARO model, further validating its ***/valueThis study introduces the integration of the ARO algorithm with the GRU for stock market prediction, marking a novel combination of efficiency and optimization. By demonstrating significant improvements in prediction accuracy and computation time, this study provides a robust and scalable solution for dynamic stock-trading systems.

The carbon dioxide emissions associated with the production of conventional Portland cement may be mitigated through the utilization of ground granulated blast furnace slag (GGBFS). The consideration of compressive strength (f (c)) is essential in the design and construction of concrete structures, as it is an essential demand in concrete mixtures. The primary objective of this study is to establish an effective approach for conducting a comprehensive evaluation of machine learning algorithms in predicting the fc of concrete that incorporates GGBFS. The work focuses on using the adaptive neuro-fuzzy inference system (ANFIS) to create predictive models for f(c). The f(c) of the collected data sets ranged from 6.3 to 101.3 MPa. The study included the artificial rabbit optimization (ARO) and Bald Eagle search algorithm (BES) to improve the effectiveness of the ANFIS approaches. The novelty of this study is attributed to several factors, including the utilization of the ARO and BES methodologies, the incorporation of GGBFS in the evaluation of f (c), the comparison with previous research findings, and the utilization of a substantial dataset encompassing multiple input variables. These factors offer a novel method for improving the effectiveness of prediction models and advance our understanding of forecasting the mechanical characteristics of concrete. The integrated ANF-AR and ANF-BA systems showed good estimating skills, according to the findings, which showed R-2 values of 0.9961 and 0.9967 for the ANF-AR's training and testing components and 0.9916 and 0.9946 for the ANF-BA, respectively. Overall, the ANFIS optimized with ARO model is recognized as the outperformed system for prediction purposes.

This paper presents an enhanced version of the artificial rabbit optimization (ARO) algorithm designed for identifying structural damage in bridge structures. The original ARO draws inspiration from survival observed in wild rabbits. However, it demands a substantial investment of computational time. Therefore, in this paper, the Improved ARO (IARO) algorithm incorporating elements of the Grey Wolf Optimizer (GWO) through hybridization, is employed to deal with optimization problems. The central concept of this approach involves infusing predator -hunting characteristics into the prey -rabbit during the hunting process, thereby enabling more effective predator evasion. The proposed method is evaluated through a series of simulations related to two real bridges: a simple supported beam structure and a steel truss bridge. The results show a significant improvement in accuracy and efficiency in determining structural damage while considering factors such as damage location, severity, and computation time. These findings underscore the potential of the proposed approach for real -world applications in structural health monitoring and damage detection.

The Perturb & Observe for MPPT algorithm is frequently utilized in solar systems. A faces significant challenges in accurately tracking peak power under changing temperature and irradiance objectives. An essay suggests a fresh idea for hybrid MPPT based on an algorithm that combines the advantages of artificial rabbit optimization (ARO) as well as P & O algorithms. A proposed algorithm overcomes the limitations of traditional P & O algorithms by capturing multiple peak power points, enabling it to adapt to rapidly changing conditions. Comparative analysis with the standard P & O technique demonstrates the suggested algorithm's advantage in terms of accuracy, efficiency, as well as reduced near-steady-state oscillations. In suggested model achieves an MPPT efficiency of approximately 96% and an overall system efficiency of around 99%. Furthermore, it exhibits a settling time of 0.1 s and a rise time of approximately 0.05 s. These impressive performance metrics highlight the potential of the hybrid ARO and considerably improve the P & O MPPT-based algorithm performance for PV systems by varying the conditions of environments.

Detecting potential power quality (PQ) events that may occur in the network is an important issue to provide safe electricity to customers. In this study, anew hybrid algorithm named adaptive fitness distance balance hybrid artificial hummingbird algorithm-artificial rabbit optimization (AFDB-AHAARO) algorithm is introduced for the detection and classification of PQ events. A hybrid algorithm is developed to improve the early convergence of the AHA algorithm by expanding the search to avoid local minima. The proposed method, unlike the optimization algorithms used in the literature, is directly applied to the detection and classification of PQ events. The performance of the proposed algorithm is investigated by 6000 different single and multiple PQ events in the Matlab in noisy and noiseless environments, considering the IEEE-1159 standards. The obtained results are compared with the AHA algorithm and the methods proposed in the literature, and it is shown that the proposed method outperforms in noisy environments. It also provides information about the time interval of PQ events. The validity of the proposed algorithm in real systems is demonstrated by testing it on the voltage signal with flicker disturbance obtained from the electrical network and on experimentally generated sag and swell events.

The assessment of the load-bearing capacity of piles holds significant importance in the design of pile foundations. This paper presents hybridized support vector regression (SVR) models by utilizing the artificial rabbit optimization (ARO) and the Black Widow optimization Algorithm (BWOA) to predict the bearing capacity of concrete piles. A repository comprising 472 reports on static load tests conducted on driven piles was employed for the study. The dataset was allocated into three parts: the training set (70%), the validation set ( 15% ), and the testing set ( 15%). Multiple criteria for assessing quality were utilized to evaluate the effectiveness of the models. The first rank belonged to the SVR model integrated with the ARO algorithm, where it could gain the higher value of R2 in all of training (R2 = 0.9876), validating (R2 = 0.9778), and testing sections (R2 = 0.9874), and the lowest value of RMSE in all the training ( RMSE = 39.393), validating ( RMSE = 53.727) and testing sections ( RMSE = 38.082). The findings indicate that the suggested model is highly appropriate for predicting the capacity of concrete piles.

Cloud manufacturing represents a pioneering service paradigm that provides flexible, personalized manufacturing services to customers via the Internet. Service composition plays a crucial role in cloud manufacturing, which focuses on integrating dispersed manufacturing services in the cloud platform into a complete composite service to form an efficient and collaborative manufacturing solution that fulfills the customer's requirements, having the highest service quality. This research presents the multi-strategy improved artificial rabbit optimization (MIARO) technique, designed to overcome the limitations with the original method, which often risks converging to local optima and have poor solution quality when dealing with optimization problems. MIARO helps the algorithm escape local optimality with L & eacute;vy flights, extends local search with the golden sine mechanism, and expands variability with Archimedean spiral mutations. MIARO is experimented on 23 benchmark functions, 3 engineering design problems, and QoS-aware cloud service composition (QoS-CSC) issues at various sizes, and the experimental findings indicate that MIARO delivers outstanding performance and offers a viable solution to the QoS-CSC problem.
