This paper proposes a new metaheuristic algorithm called dwarf mongoose optimization algorithm (DMO) to solve the classical and CEC 2020 benchmark functions and 12 continuous/discrete engineering optimization problems. The DMO mimics the foraging behavior of the dwarfmongoose. The restrictive mode of prey capture (feeding) has dramatically affected the mongooses' social behavior and ecological adaptations to compensate for efficient family nutrition. The compensatory behavioral adaptations of the mongoose are prey size, space utilization, group size, and food provisioning. Three social groups of the dwarfmongoose are used in the proposed algorithm, the alpha group, babysitters, and the scout group. The family forage as a unit, and the alpha female initiates foraging, determines the foraging path, the distance covered, and the sleeping mounds. A certain number of the mongoose population (usually a mixture of males and females) serve as the babysitters. They remain with the young until the group returns at midday or evening. The babysitters are exchanged for the first to forage with the group (exploitation phase). The dwarfmongooses do not build a nest for their young;they move them from one sleeping mound to another and do not return to the previously foraged site. The dwarfmongoose has adopted a seminomadic way of life in a territory large enough to support the entire group (exploration phase). The nomadic behavior prevents overexploitation of a particular area. It also ensures exploration of the whole territory because no previously visited sleeping mound is returned. The performance of the proposed DMO algorithm is compared with seven other algorithms to show its effectiveness in terms of different performance metrics and statistics. In most cases, the near-optimal solutions achieved by the DMO are better than the best solutions obtained by the current state-of-the-art algorithms. Matlab codes of DMO are available at https://*** ***/matlabcentral/fi

The dwarf mongoose optimization algorithm is a metaheuristic approach designed to solve single-objective optimization problems. However, DMO has certain limitations, including slow convergence rates and a tendency to get stuck in local optima, particularly when applied to multimodal and combinatorial problems. This paper introduces an enhanced version of the DMO, referred to as HDMO, which is based on a hybrid strategy. Firstly, a sine chaotic mapping function is integrated to enhance the diversity of the initial population. Secondly, the study aims to improve the algorithm's performance through the integration of nonlinear control, adaptive parameter tuning, hybrid mutation strategies, and refined exploration-exploitation mechanisms. To evaluate the performance of the proposed HDMO, we conducted tests on the CEC2017, CEC2020, and CEC2022 benchmark problems, as well as 19 engineering design problems from the CEC2020 real-world optimization suite. The HDMO algorithm was compared with various algorithms, including (1) highly cited algorithms such as PSO, GWO, WOA and SSA;(2) recently proposed advanced algorithms, namely, BOA, GBO, HHO, SMA and STOA;and (3) high-performance algorithms like LSHADE and LSHADE_SPACMA. Experimental results demonstrate that, compared to other algorithms, HDMO exhibits superior convergence speed and accuracy. Wilcoxon rank-sum test statistics confirm the significant performance improvement of HDMO, highlight its potential in practical engineering optimization and design problems.

Security in smart cities is a challenging issue in urban environments as they depend upon interconnected technologies and data for effective services. To address security challenges, smart cities implement robust cybersecurity measures, including network monitoring, encryption, and intrusion detection systems. Detecting and mitigating possible security risks in drone network B5G is a crucial aspect of ensuring reliable and safe drone operation. It is necessary to establish sophisticated and robust attack detection techniques to defend against security threats as the use of drones becomes increasingly widespread and their applications diversify. This is due to the lack of privacy and security consideration in the drone's system, including an inadequate computation capability and unsecured wireless channels to perform advanced cryptographic algorithms. Intrusion detection systems (IDS) and anomaly detection systems can identify suspicious activities and monitor network traffic, such as anomalous communication patterns or unauthorized access attempts. Therefore, the study presents an enhanced dwarf mongoose optimization algorithm with deep learning-based attack detection (EDMOA-DLAD) in Networks B5G for the purpose of Drones technique. The presented EDMOA-DLAD technique aims to recognize the attacks and classifies them on the drone network B5G. Primarily, the EDMOA-DLAD technique designs a feature selection (FS) approach using EDMOA. To detect attacks, the EDMOA-DLAD technique uses a deep variational autoencoder (DVAE) classifier. Finally, the EDMOA-DLAD technique applies the beetle antenna search (BAS) technique for the optimum hyperparameter part of DVAE model. The outcome of EDMOA-DLAD approach can be verified on benchmark datasets. A wide range of simulations inferred that the EDMOA-DLAD method obtains enhanced performance of 99.79% over other classification techniques.

QRS detection is the essential electrocardiogram (ECG) analysis procedure. A reliable QRS recognition system that achieves high accuracy despite a typical QRS morphologies and significant noise is required for ECG data gathered by wearable devices. Most contemporary systems seek fast execution durations and minimal energy consumption while attaining high prediction rates. To minimize these issues, this research article presents an approach of multi-head self-attention-based recurrent neural network with dwarf mongoose optimization algorithm-espoused QRS detector design (MHSARNN-QRS) is proposed. Initially, ECG data are taken from MIT/BIH arrhythmia dataset (MIT-AD). Every disintegrated signal is transmitted to multi-head self-attention-based recurrent neural network (MHSARNN) to examine morphologies and predict QRS like correct and incorrect. Then, the QRS wave is located through dwarf mongoose optimization algorithm by reducing probability of neglected identification improves the detection performance. The performance of proposed MHSARNN-QRS method is evaluated using accuracy, sensitivity, specificity, detection error rate, computation time, f1-score, positive prediction, and time for processing a single record (s) and single beat (ms) are analyzed. Performance of the MHSARNN-QRS approach attains high sensitivity, lower single record, lower single beat, and greater accuracy compared with existing methods.

Recently, optimization problems have been revised in many domains, and they need powerful search methods to address them. In this paper, a novel hybrid optimizationalgorithm is proposed to solve various benchmark functions, which is called IPDOA. The proposed method is based on enhancing the search process of the Prairie Dog optimizationalgorithm (PDOA) by using the primary updating mechanism of the dwarf mongoose optimization algorithm (DMOA). The main aim of the proposed IPDOA is to avoid the main weaknesses of the original methods;these weaknesses are poor convergence ability, the imbalance between the search process, and premature convergence. Experiments are conducted on 23 standard benchmark functions, and the results are compared with similar methods from the literature. The results are recorded in terms of the best, worst, and average fitness function, showing that the proposed method is more vital to deal with various problems than other methods.

The dwarf mongoose optimization algorithm (DMO) is a popular metaheuristic algorithm utilized to solve real-world problems. However, DMO has limitations such as slow convergence rate, susceptibility to local optima, and poor performance in high-dimensional problems. Aiming at the defects of the DMO, we propose an improved version called IDMO. This paper introduces the best leader and proposes a novel nonlinear control strategy based on the sine function, significantly enhancing the convergence rate while ensuring accuracy. Moreover, we propose a novel exploration strategy to solve the global optimization and high-dimensional problem. To demonstrate the performance of the proposed IDMO, we test on 65 test functions, including CEC2017, CEC2020, CEC2022, and CEC2013 large-scale global optimization. IDMO is compared with three classes of widely recognized algorithms: (1) highly-cited algorithms, namely, GSA, GWO, WOA, and HHO, (2) advanced algo-rithms, such as CPSOGSA, CSA, AVOA, and SO, (3) high-performance optimizers including L-SHADE, AL-SHADE, LSHADE-SPACMA, and LSHADE-cnEpSin. Moreover, we also compare with the original DMO and variants such as GDNNMOA, CO-DWO, and BDMOSAO. Meanwhile, we apply IDMO to solve 19 engineering design problems from the CEC2020 real-world optimization suite. Experimental results demonstrate that IDMO outperforms other algorithms, exhibiting excellent convergence rate, stability, and accuracy. The effectiveness of IDMO is confirmed by the Friedman mean ranking, showcasing its potential for metaheuristic optimization and real-world engineering design problems.

One of the main sources of the Sudden Cardiac Death (SCD) is termed as Fatal arrhythmia. The electric shock treatment retrieves the regular electrical and mechanical functions of the heartbeat by controlling Ventricular fibrillation (VF) and Ventricular Tachycardia (VT). Shockable arrhythmia is easily controlled by providing electrical shock treatments. On the other hand, non-shockable arrhythmia is not controlled by electrical shock treatment. It is a very complex task to accurately discriminate these two kinds of arrhythmia using human assessment of Electrocardiogram (ECG) signals within a limited span and there may be a chance to occur faults during manual inspection. An accurate ECG diagnosis is very significant as it saves the life of the patient in advance by delivering proper therapy. To address this emerging problem, an automated model using the proposed dwarfmongoose Gannet optimizationalgorithm-Deep Neuro-Fuzzy Network (DMGOA-DNFN) is invented for detecting the shockable ventricular cardiac arrhythmias (SVCA). The classification is performed effectively utilizing DNFN and the weight of this classifier is optimally adjusted employing a newly developed algorithm named DMGOA, which is a consolidation of dwarfmongooseoptimization (DMO) and Gannet optimizationalgorithm (GOA). The proposed DMGOA-DNFN has surpassed other classical models with respect to accuracy of 93.2%, sensitivity of 95.8%, and specificity of 91.7%.

Combinatorial Test Case Prioritization is a technique used in software testing to improve the efficiency and effectiveness of test suites. It involves selecting and ordering test cases based on their ability to detect faults, especially those caused by interactions between multiple parameters. Artificial Intelligence (AI) has made significant contributions to Combinatorial Test Case Prioritization (TCP) by introducing advanced techniques to enhance the efficiency of the testing process. However, managing dependencies between test cases and adjusting the prioritization accordingly can be complex and time-consuming in most of the previous techniques. Therefore, an Energy Valley dwarf mongoose optimization algorithm (EVDMOA) is devised for Combinatorial TCP. Initially, the software programs are collected from the dataset. Then, test case generation is performed to create the test suites. Next, the combinatorial TCP is performed. Here, the fitness parameters such as Average Percentage of Fault Detected (APFD), Average Percentage of Branch Coverage (APBC), and weight are considered for fitness evaluation. Moreover, the weights in the fitness function are computed by the Deep Q Net (DQN), which is trained by the proposed EVDMOA. At last, the prioritized test cases are obtained. The EVDMOA achieves the AFPD, APBC, and fitness values of 0.907, 0.914, and 0.926. Moreover, the EVDMOA helps in maintaining the overall quality and reliability of the software.
