Isolated solar hybrid systems with backup options are critical for providing reliable energy in remote areas. This study presents a technical-economic-environmental analysis and optimal design of three isolated solar hybrid configurations that incorporate hydrogen energy storage, battery energy storage, and diesel generators. Using real hourly meteorological data, an enhanced particle swarm optimization (PSO) algorithm was applied to minimize the total net annual cost (TNAC), improve system reliability, and reduce lifecycle emissions (LCE). The study also investigates the impact of reliability, varying subsidy levels for photovoltaic (PV) and different backup technologies and carbon prices on system designs, while sensitivity analyses examine the effects of PV costs, interest rates, fuel prices, solar irradiance, and load demands on the optimal results. Simulation results reveal that the enhanced PSO reduces TNAC by approximately 2.5 % relative to standard PSO and by about 23.1 % compared to Simulated Annealing (SA), while reducing computational time by 25.7 % compared to PSO and 5.3 % compared to SA. Compared to the solar/diesel system, the LCE for the solar/battery and solar/hydrogen systems decreased by 93.8 % and 87.1 %, respectively. These findings indicate that although the Solar/Diesel system may be cost-effective initially, its high emissions and sensitivity to fuel price fluctuations render it less sustainable. In contrast, the Solar/Battery system offers the most favorable environmental profile, while the Solar/Hydrogen system, despite higher upfront costs, provides superior long-term reliability and sustainability. This study offers practical guidelines for selecting backup systems based on economic, environmental, and reliability criteria. © 2025 Hydrogen Energy Publications LLC

Heuristic algorithms have evolved rapidly, leading to numerous theoretical breakthroughs and wide applications in various fields. swarm intelligence algorithms, as an important branch of heuristic algorithms, have attracted significant attention from researchers. With the expansion of application scenarios and increasing problem complexity, swarm intelligence algorithms have faced considerable challenges in dealing with high-dimensional, multimodal complex function optimization. As a novel swarm intelligence algorithm, the Wolf Pack algorithm (WPA) has emerged as an efficient tool for addressing such issues due to its unique swarm characteristics and the mechanism that simulates wolf pack hunting behavior. A systematic review and summary of WPA from the perspectives of biological characteristics and algorithm principles are of paramount significance. Subsequently, a comparison between WPA and commonly used swarm intelligence algorithms is conducted. Then, the research progress of WPA is discussed in terms of both theory and application. Finally, inadequacies of WPA are explored, and the future prospects are presented.

We use conventional adaptive optical system to compensate atmospheric turbulence in free space optical (FSO) communication system under strong scintillation circumstances, undesired wave-front measurements based on Shark-Hartman sensor (SH). Since wavefront sensor-less adaptive optics is a feasible option, we propose several swarm intelligence algorithms to compensate the wavefront aberration from atmospheric interference in FSO and mainly discuss the algorithm principle, basic flows, and simulation result. The numerical simulation experiment and result analysis show that compared with SPGD algorithm, the proposed algorithms can effectively restrain wavefront aberration, and improve convergence rate of the algorithms and the coupling efficiency of receiver in large extent.

With the improvement of computer computing speed and the development of swarm intelligence algorithms, more and more swarm intelligence algorithms are used in the research of crowd evacuation. Firstly, some typical swarm intelligence algorithms are introduced. And their performances and applicable scenarios are compared and analyzed. Based on the analysis of various swarm intelligence algorithms, a new crowd evacuation model based on swarm intelligence algorithm is proposed in this paper. This model is based on dynamic grouping principle, driven by particle swarm optimization in microscopic perspective and artificial bee colony algorithm in macroscopic perspective. It fully combines the advantages of particle swarm optimization (PSO) to simulate the crowd more realistically with the advantages of artificial bee colony algorithm for global optimization. This proposed model also has better computational convergence, which can provide a professional basis for crowd evacuation.

Personalized tourist route planning (TRP) and navigation are online or real-time applications whose mathematical modeling leads to complex optimization problems. These problems are usually formulated with mathematical programming and can be described as NP hard problems. Moreover, the state-of-the-art (SOA) path search algorithms do not perform efficiently in solving multi-objective optimization (MO) problems making them inappropriate for real-time processing. To address the above limitations and the need for online processing, a swarm intelligence graph-based pathfinding algorithm (SIGPA) for MO route planning was developed. SIGPA generates a population whose individuals move in a greedy approach based on A* algorithm to search the solution space from different directions. It can be used to find an optimal path for every graph-based problem under various objectives. To test SIGPA, a generic MOTRP formulation is proposed. A generic TRP formulation remains a challenge since it has not been studied thoroughly in the literature. To this end, a novel mixed binary quadratic programming model is proposed for generating personalized TRP based on multi-objective criteria and user preferences, supporting, also, electric vehicles or sensitive social groups in outdoor cultural environments. The model targets to optimize the route under various factors that the user can choose, such as travelled distance, smoothness of route without multiple deviations, safety and cultural interest. The proposed model was compared to five SOA models for addressing TRP problems in 120 various scenarios solved with CPLEX solver and SIGPA. SIGPA was also tested in real scenarios with A* algorithm. The results proved the effectiveness of our model in terms of optimality but also the efficiency of SIGPA in terms of computing time. The convergence and the fitness landscape analysis showed that SIGPA achieved quality solutions with stable convergence.

Energy conservation in buildings is of vital importance for solving the problem of global warming and energy scarcity in today's world. In this paper, we discuss the optimal control methods of the heating, ventilation, and air-conditioning (HVAC) system using swarm intelligence algorithms to reduce energy consumption of buildings. The performances of ten optimization algorithms are compared. The results on test functions manifest the artificial bee colony algorithm (ABC) exhibits the best performance among the focused optimization algorithms. Taking a real HVAC system as an example, the holistic energy models of equipment in the HVAC system are established and validated. Then, the focused algorithms are used for the optimal control of a real HVAC system aiming at energy conservation. The simulated results based on 24-h real operation data show that the energy -saving ratio through by the ABC can reach 24.07% on average. The work in this study will contribute to the building energy conservation and carbon neutral development in the future.

Passive localization and classification algorithms for mixed near-field and far-field sources have mainly been investigated for antenna arrays with regular or symmetrical geometry. However, these algorithms may not be applicable to wireless sensor networks, where spatially distributed sensor nodes form an array of random geometry. This paper proposes squared error norm of residual fitting error matrix (SRFEM) cost function for mixed source localization, which does not place any constraint on the geometry of antenna array. The proposed cost function is optimized using computationally simple swarm intelligence (SI) algorithms. Convergence performance of three SI algorithms, i.e., particle swarm optimization, Whale optimization, and Grey Wolf optimization is investigated to obtain estimates of the source location parameters with a minimal number of iterations or computational complexity. In order to provide robustness for the SRFEM cost function, this paper proposes an impulse denoising technique based on the long-short term memory recurrent neural network (LSTM-RNN). Simulation results confirm that, in the presence of AWGN, the proposed SRFEM cost function outperforms existing techniques based on the uniform linear array and approaches the theoretical Cramer-Rao lower bound even for a fewer number of snapshots. Further, simulation analysis also reveals that LSTM-RNN provides better mixed localization performance under impulse noise as compared to the bounded noise covariance approach at high signal-to-noise values.

Differential privacy may have a potential optimization effect on some swarm intelligence algorithms besides privacy-preserving

Differential privacy (DP), as a promising privacy-preserving model, has attracted great interest from researchers in recent years. At present, research on the combination of deep learning and DP is active. In contrast, another widely used artificial intelligence technique, swarm intelligence (SI), has received little attention in the context of DP even though it also triggers privacy concerns. For this reason, this paper attempts to combine DP and SI for the first time and proposes a general differentially private swarm intelligence algorithm framework (DPSIAF). By utilizing the exponential mechanism, this framework can easily develop existing SI algorithms into the private versions. As examples, we apply it to four popular SI algorithms, and the related analyses demonstrate the effectiveness of our DPSIAF. More importantly, our private algorithms also exhibit some interesting experimental phenomena. In some cases, their performance is not strictly affected by the privacy budget, and one of them even outperforms its non-private version. These findings are different from the conventional cognition, which indicates DP owns the potential to serve as an optimization tool for some SI algorithms. Our study may provide a new perspective on DP and promote the synergy between metaheuristic optimization community and privacy computing community.

A Novel Deployment Strategy Based on Improved Gradient-Based Optimizer for BLE Anchor Nodes

Bluetooth low energy (BLE) technology has gained attraction for indoor localization in recent years due to its low power consumption and cost-effectiveness. However, deploying BLE anchor nodes in indoor environments, particularly in areas with obstacles that can interfere with signal strength, remains a major challenge. This paper proposes a novel deployment strategy that utilizes an improved gradient-based optimizer (GBO) algorithm to address these challenges. The primary objective is to improve both the coverage of BLE anchor nodes and the accuracy of localization. To assess the effectiveness of the deployment schemes generated by the algorithm, we introduce a comprehensive performance evaluation metric. This metric integrates multiple indicators, including capability rate, geometric accuracy factor, penalty term, sensor network topology, and network uniformity. An obstacle perception model is also introduced to mitigate the impact of deviations between measured values from the RSSI ranging model in obstacle-rich environments and actual ground truth values. This model adjusts the measurements to enhance the reliability of the localization process. The presented algorithm is tested in an indoor space with obstacles. Experimental results demonstrate that the novel algorithm significantly optimizes anchor node layouts, enhancing coverage, and localization accuracy. Compared with the existing algorithms, the proposed method shows better performances and highlights its potential for more accurate and efficient BLE indoor localization. In particular, our research achieved an 86% probability of positioning errors within 3 m, surpassing the best results of other deployment schemes by approximately 11%. This highlights the potential of our approach for more accurate and efficient BLE-based indoor localization.
