The field of optimization problems has garnered significant attention due to its importance across various applications, particularly driven by the demand for efficient solutions to complex engineering challenges. Numerous metaheuristic algorithms inspired by animal behaviour or swarm intelligence have been proposed;however, these algorithms often pursue a multitude of strategies, resulting in excessive parameters that complicate tuning and hinder convergence and balance. Additionally, algorithms based on human behaviour remain scarce. To address these limitations, extensive research has been conducted on the interplay between social memory and individual memory, leading to the introduction of a novel human-behaviour-inspired metaheuristic algorithm, named Advanced Social Memory Optimization (ASMO). This algorithm seeks to address the complexities of parameter management, convergence, and balance more effectively with a streamlined set of strategies. Furthermore, a mathematical model based on the mechanisms of social memory formation and individual memory updating underpins the algorithm. Rigorous performance evaluations, utilizing the Wilcoxon Rank-Sum Test and the Friedman Test across multiple benchmark suites (CEC2017, CEC2019, and CEC2022), demonstrate that ASMO, with only two algorithmic strategies, outperforms or matches established algorithms on more than half of the test functions. These findings suggest promising new avenues for research in the field of optimization and, given the succinctness of ASMO's strategies, underscore its potential as a powerful tool for enhancing and developing solutions to complex engineering design problems. The code for the ASMO algorithm is available in appendix D.

Air traffic controllers face a daily challenge ensuring the safe and orderly flow of aircraft in terminal maneuvering areas, known academically as the Aircraft Sequencing and Scheduling Problem (ASSP). Typically formulated as a mixed integer linear programming problem, the strong NP-hard nature of the ASSP necessitates the use of heuristics or metaheuristics for practical, time-efficient solutions. In this paper, we propose a new metaheuristic algorithm to address the computational complexity of the problem. The algorithm employs a single-solution-based search methodology that starts from a well-constructed initial solution and iteratively explores a fix-and-optimize procedure to find an improved solution. Specifically, this procedure solves a variant of the ASSP that contains all the continuous variables and a selected subset of binary variables of the original problem, with the remaining binary variables being temporarily fixed to the values determined based on previous iterations. Additionally, the algorithm incorporates tabu search to increase the possibility of quickly finding optimal solutions. A rolling horizon control approach further accelerates the solution derivation process by decomposing the original problem into smaller subproblems. Our computational experiments using real traffic data from Guangzhou Baiyun International Airport demonstrates the effectiveness of the algorithm in terms of solution quality and computational time.

metaheuristic algorithms are extensively utilized in engineering due to their outstanding capacity for solving optimization problems with restricted computing resources or incomplete data. However, its extended use is constrained by the low optimization accuracy and premature convergence. The rapid spread and extensive reach of the COVID-19 virus have inspired the proposal of a new virus diffusion algorithm (VDA) to overcome the limitations of the metaheuristic algorithm. This article utilizes the VDA algorithm to segment spun cracks, providing a method for intelligent detection of spinning process. The algorithm integrates global diffusion and local diffusion mechanisms to simulate both the random walk and local disturbance modes of virus diffusion, thereby enhancing its accuracy. Additionally, it introduces the competition mechanism and infection center rate to enhance the diversity of the population and expand the algorithm's search range. The effectiveness and robustness of the VDA algorithm is validated using the CEC'17 test benchmark function. Subsequently, the VDA algorithm is used to segment images with cracks in thin-walled spun parts. The experimentally obtained results illustrate that the VDA-based segmentation algorithm attains a PSNR of 23.6798 and an SSIM of 0.9864 for crack images, surpassing other segmentation algorithms in challenging conditions.

The ascent of geometry-based models and methodologies, exemplified by geometric deep learning and manifold numerical optimization algorithms, has inaugurated a novel domain across various applications that grapple with geometric data complexities, such as electroencephalogram signals represented by symmetric positive definite matrix manifold, hierarchical data represented by hyperbolic manifold. The imperative fuels this inevitable paradigm shift to encapsulate the intricacies and richness inherent in data, areas where traditional methods prove inadequate. While metaheuristic algorithms are renowned for their versatile adaptability across applications, offering practical solutions within reasonable timeframes. However, the conventional metaheuristic algorithms fail on manifold applications with meaningless solutions. From an extrinsic optimization perspective, we treat manifold optimization problems as general optimization problems with multiple fused constraints that limit the optimization path to the manifold. This study pioneered the proposal and implementation of a metaheuristic manifold optimization, introducing a novel directional transport operator to rectify previously identified issues. Through experimentation across five sets of 25 problems, comparing against five algorithms, including both gradient-free and gradient-dominant counterparts, our proposed algorithm emerges as the optimal performer within the gradient-free category, demonstrating competitiveness even against gradient-dominant algorithms. Furthermore, we applied the proposed algorithm to the robot dynamic manipulation problem, achieving a close-optimal solution that eludes gradient-dominant approaches. This paper delves into the inherent capabilities and establishes the generalization of a metaheuristic algorithm within non-Euclidean functional landscapes.

A mega-braced frame is one of the well-known structural systems used in tall buildings to resist lateral forces, which is composed of networks of diagonal braces and structural elements strategically placed within the building's frame to enhance its stiffness and stability. Determining the optimal angle of mega bracing in buildings presents challenges due to complex structural considerations, such as lateral load distribution, ensuring compatibility with building geometry and layout, and optimizing the overall structural efficiency while maintaining seismic integrity. For this purpose, a novel approach is proposed in this study for seismic optimization of steel mega-braced frames by employing an enhanced version of the prairie dog optimization (PDO) algorithm as one of the recently proposed metaheuristic algorithms. The new improved version of this algorithm called I-PDO is developed based the Levy flight concept, whereas the conventional Brownian randomization is replaced by Levy flight in the main search loop of the algorithm. For numerical investigations, a 10-story, 1-bay, and a 24-story, 5-bay, frame structures are considered. An optimization problem is developed based on the topology optimization of the mega bracing system, whereas a size optimization is also conducted for optimal determination of the design sections for structural elements. For comparative investigations, some of the well-known metaheuristics are also used for performance evaluation of the I-PDO in dealing with the structural optimization problems. The results demonstrate the capability of the I-PDO in providing better optimization results in dealing with the topology and size optimization of the mega-braced frame structures.

To efficiently utilize the power generated by a photovoltaic (PV) system, integrating it with an energy storage system (ESS) is essential. Furthermore, maximizing the economic benefits of such PV-ESS integrated systems requires selecting the optimal capacity and performing optimal energy operation scheduling. Although many studies rely on rule-based energy operation scheduling, these methods prove inadequate for complex real-world scenarios. Moreover, they often focus solely on determining the ESS capacity to integrate into existing PV systems, thereby limiting the possibility of achieving optimal economic benefits. To address this issue, we propose an optimal energy operation scheduling and system sizing scheme for a PV-ESS integrated system based on metaheuristic algorithms. The proposed scheme employs a zero-shot PV power forecasting model to estimate the potential power generation from a planned PV system. A systematic analysis of the installation, operation, and maintenance costs is then incorporated into the economic analysis. We conducted extensive experiments for comparing economic benefits of various scheduling methods and capacities using real electrical load data collected from a private university in South Korea and estimated PV power data. According to the results, the most effective metaheuristic algorithm for scheduling is simulated annealing (SA). Additionally, the optimal PV system, battery, and power conversion system capacities for the university are 13,000 kW each, 10% of the PV system capacity, and 60% of the battery capacity, respectively. The estimated annual electricity tariff calculated from the data used in the experiment is $3,315,484. In contrast, SA-based scheduling in the optimal PV-ESS integrated system achieved annual economic benefits of $875,000, an improvement of approximately 7% over rule-based scheduling of $817,730.

Although the diversity of metaheuristic algorithms has been frequently highlighted, the similarity of these algorithms is not studied comprehensively. This work studies the similarity of metahruristic algorithms from their performance perspective captured in a newly proposed fractional ranking method, which can map comprehensive performance measures into a scalar framework. The fractional ranking data is clustered using a k-medoids clustering to find similarities between algorithms. Results show that the proposed similarity analysis scheme reveals a new perspective of metaheuristic algorithms.

With the standard of medical treatment raised up, the number of population is increased. People need to the extent new space for living. The convenient traffic is part of people life. Internet of things (IoT) promotes the development of riding-sharing which solving traffic blocked problem and made transportation flexible. This paper focuses on multi-people path planning by sharing vehicle problem to have more convenient traffic. In the current, public transports have fixed route so that passengers need to wait for the bus at the bus stop. The route path always cannot satisfy the request of customers. This paper adopts novelty concept of the ride-sharing to solve multi-path and passenger schedule planning problem to have highly flexible traffic method. We considering the waiting time of passenger and short path problem, and then propose two algorithms based on metaheuristic algorithm. Simulation represents that proposed method can design the best-shared vehicle path for different environments.

The metaheuristic algorithm is a very important area of research that continuously improves in solving optimization problems. Nature-inspired is one of the metaheuristic algorithm classifications that has grown in popularity among researchers over the last few decades. Nature-inspired metaheuristic algorithms contribute significantly to tackling many standing complex problems (such as the combinatorial t-way testing problem) and achieving optimal results. One challenge in this area is the combinatorial explosion problem, which is always intended to find the most optimal final test suite that will cover all combinations of a given interaction strength. As such, test case generation has been selected as the most active research area in combinatorial t-way testing as Non-deterministic Polynomial-Time Hardness (NP-hard). However, not all metaheuristics are effectively adopted in combinatorial t-way testing, some proved to be effective and thus have been popular tools selected for optimization, whilst others were not. This research paper outlines a hundred and ten (110) outstanding nature-inspired metaheuristic algorithms for the last decades (2001 and 2021), such as the Coronavirus Optimization algorithm, Ebola Optimization algorithm, Harmony Search, Tiki-Taka algorithm, and so on. The purpose of this review is to revisit and carry out an up-to-date review of these distinguished algorithms with their respective current states of use. This is to inspire future research in the field of combinatorial t-way testing for better optimization. Thus, we found that all metaheuristics have a simple structure that can be adopted in different areas to become more efficient in optimization. Finally, we suggested some future paths of investigation for researchers who are interested in the combinatorial t-way testing field to employ more of these algorithms by tuning their parameters settings to achieve an optimal solution.

This study introduces a novel metaheuristic algorithm, Leaf in Wind Optimization, inspired by the natural phenomenon of falling leaves in the wind. The proposed method simulates the motion response of leaves in varying intensities of wind by establishing models for light wind-driven blades and strong wind-driven blades. The algorithm incorporates motion modes of linear translation and spiral rotation induced by wind, offering a hybrid search framework suitable for both strategies. This approach enables enhanced exploration and exploitation of the search space. The algorithm's performance was evaluated using three challenging benchmark test sets, CEC 2017, CEC 2019 and CEC 2022, as well as an engineering practical problem. Its effectiveness was assessed through comparison with 10 random optimization algorithms, namely: Tree Seed algorithm, Multi-Verse Optimizer, Salp Swarm algorithm, Artificial Ecosystem-based Optimization, Hunger Games Search, Fox Optimizer, Spider Wasp Optimizer, AOBLMOA, Enhanced Snake Optimizer, and IbI Logic algorithm. In the comprehensive testing conducted, the proposed algorithm consistently outperformed other optimizers in approximately 82% of comparisons. Through examination of convergence curves and statistical data, it is evident that Leaf in Wind Optimization demonstrates superior potential compared to the alternative optimizers under consideration.
