The search and rescue optimization algorithm (SAR) is a recent metaheuristic inspired by the explorations behavior of humans during search and rescue operations. Similar to many of the metaheuristic algorithms (MAs), SAR may suffer from drawbacks, such as being trapped in minimum local regions and improper balance between exploitation and exploration phases. To overcome these weaknesses, this study proposes an alternative algorithm of search and rescue optimization algorithm (SAR) called (mSAR) to improve its diversity and provide a soft balance between the exploration and exploitation stages of the original SAR algorithm. The mSAR introduces an adaptive strategy to boost the algorithm performance. To assess its reliability, the proposed approach is validated through IEEE CEC'2020 test suite against six state-of-the-art algorithms namely the Adaptive guided differential evolution algorithm (AGDE), Evolution strategy with covariance matrix adaptation (CMA-ES), the Whale optimizationalgorithm (WOA), Harris hawks optimization (HHO), Archimedes optimizationalgorithm (AOA), Cuckoo searchalgorithm (CS) besides the original SAR algorithm. A robust strategy based on a mSAR to create an equivalent circuit for a high-efficiency triple-junction solar cell/module (TJS/M) has been proposed. The suggested strategy is used to determine the best parameters of the TJS/M model based on the measurement datasets. During the optimization process, the aim is to minimize the integral time absolute error (ITAE) between the measured and estimated currents. The suggested mSAR is compared with other optimizers considering statistical tests of Wilcoxon sign rank, Friedman, and ANOVA. For the case of TJSC based PV module, the best (minimum) objective function is achieved at a value of 0.00178 by the proposed mSAR, whereas the worst value at 0.02476 is obtained by the CS. Furthermore, for the single TJSC, the minimum objective function is achieved at value of 0.04277 by the proposed mSAR wher

Unmanned aerial vehicle (UAV) path planning plays an important role in the flight process of an UAV, which needs an effective algorithm to deal with UAV path planning problem. The search and rescue optimization algorithm (SAR) is easy to implement and has the characteristics of flexible, but it has slow convergence speed and has not been applied to UAV path planning. To address these problems, a heuristic crossing search and rescue optimization algorithm (HC-SAR) is proposed. HC-SAR combines a heuristic crossover strategy with the basic SAR to improve the convergence speed and maintain the population diversity in the optimization process. Furthermore, a real-time path adjustment strategy is proposed to straighten the UAV flight path. In addition, cubic B-spline interpolation is used to smooth the generated path. Comprehensive experiments including two-dimensional and three-dimensional environments for different threat zone are conducted to validate the performance of HC-SAR. The results show that HC-SAR has a high convergence speed and can successfully obtain a safe and efficient path, and it significantly outperforms SAR, differential evolution (DE), ant lion optimizer (ALO), squirrel searchalgorithm (SSA) and salp swarm algorithm (SSA) in all the cases. These results suggest that the proposed algorithm can effectively serve as an alternative for solving UAV path planning problem.

A new optimization method namely the search and rescue optimization algorithm (SAR) is presented here to solve constrained engineering optimization problems. This metaheuristic algorithm imitates the explorations behavior of humans during search and rescue operations. The e-constrained method is utilized as a constraint-handling technique. Besides, a restart strategy is proposed to avoid local infeasible minima in some complex constrained optimization problems. SAR is applied to solve 18 benchmark constraint functions presented in CEC 2010, 13 benchmark constraint functions, and 7 constrained engineering design problems reported in the specialized literature. The performance of SAR is compared with some state-of-the-art optimizationalgorithms. According to the statistical comparison results, the performance of SAR is better or highly competitive against the compared algorithms on most of the studied problems. (c) 2020 Elsevier Ltd.

In recent days, the expansion of e-waste disposal should be increased due to environmental hazards, contamination of groundwater, an unconcerned consequence on marine life, human health, and decrease in the fertility of the soil. The majority of the developing countries are facing massive issues in implementing sustainable e-waste management schemes. The unofficial e-waste management schemes in the region of Chandigarh, India, have become a serious dispute for the government and several stakeholders due to human health and environmental effects. To overcome such shortcomings, this paper proposes an efficient e-waste management system using fuzzy c-means based adaptive optimal neural network. Here fuzzy c-means clustering approach is employed to classify the household e-wastes and adaptive optimal neural network is employed to analyze the relative weights as well as the grading of the obstructions. Here, the financial and economic limitations are regarded as the most important obstructions of e-waste formalization. The sensitivity analysis is carried out to verify the structure robustness and address the bias effect. This study assists the lawmakers to create organized strategies for an efficient e-waste management system. The sustainable set of e-waste management system advances the e-waste management in India quality thereby raising the recycling rate to 40%.

The growing popularity of hydrogen fuel cell vehicles (HFCVs) and electric vehicles (EVs) has led to the widespread adoption of multi-energy microgrids (MEMGs), which seamlessly integrate hydrogen refueling station systems (HRSS) and electric vehicle parking lots (EVPLs). Power-to-hydrogen (P2H2) technology has been instrumental in enabling this transition. To further enhance the efficiency and reliability of MEMG systems, a network structure known as a multi-microgrid (MMG) has emerged. This research introduces a robust decentralized framework for energy management, with a focus on optimizing day-ahead planning for interconnected microgrids (MGs). The MMG configuration includes hydrogen provider companies (HPCs) and electricity markets, integrating cutting-edge technologies such as power-to-heat (P2H) units, P2H2 units, combined heat and power (CHP) units, and various energy storage systems (ESSs). Maintaining data privacy is a key concern for interconnected MGs operating within an MMG. To address this, the study proposes the use of a search and rescueoptimization (SARO) algorithm, which strengthens local and global search capabilities while safeguarding data privacy. Furthermore, the MMG integrates a demand response program (DRP) that efficiently manages electricity consumption through price signals, leading to greater cost-effectiveness and energy efficiency. Simulation results confirm the effectiveness of the proposed decentralized model in meeting diverse energy requirements, even in challenging scenarios with fluctuating electricity market prices.

Recently, automated retinal image processing has been considered a competitive field of research due to the low-accuracy results, complexity, and unacceptable outcomes associated with it. In this article, we proposed a novel approach for the classification of fundus images from different kinds of fundus disorders. The original images are preprocessed in terms of noise and contrast enhancement by using the contrast limited adaptive histogram equalization method. The optic cup segmentation from the fundus images is effectively handled via the search and rescue optimization algorithm. After that, the color, texture, and shape-based gray-level co-occurrence matrix features are extracted. The hybrid particle swarm optimization with local search strategy improves the DNN parameter and the newly developed method is named as optimal DNN. The optimal DNN is used to classify whether the image is diabetic retinopathy, glaucoma, or age-related macular degeneration. Experimentally, different kinds of datasets such as STARE, Drishti, and RIM-One datasets with performance measure are validated. Finally, the proposed approaches demonstrate higher classification performances in terms of accuracy, specificity, sensitivity, precision, recall, and f-measure.
