To solve the problems of premature convergence and easily falling into local optimum, a whale optimization algorithm based on dynamic pinhole imaging and adaptive strategy is proposed in this paper. In the exploitation phase, the dynamic pinhole imaging strategy allows the whale population to approach the optimal solution faster, thereby accelerating the convergence speed of the algorithm. In the exploration phase, adaptive inertial weights based on dynamic boundaries and dimensions can enrich the diversity of the population and balance the algorithm's exploitation and exploration capabilities. The local mutation mechanism can adjust the search range of the algorithm dynamically. The improved algorithm has been extensively tested in 20 well-known benchmark functions and four complex constrained engineering optimization problems, and compared with the ones of other improved algorithms presented in literatures. The test results show that the improved algorithm has faster convergence speed and higher convergence accuracy and can effectively jump out of the local optimum.

whale optimization algorithm (WOA) is a population-based meta-heuristic imitating the hunting behavior of humpback whales, which has been successfully applied to solve many real-world problems. Although WOA has a good convergence rate, it cannot achieve good results in finding the global optimal solution of high-dimensional complex optimization problems. The learning mechanism of Lamarckian evolutionism has the advantages of speeding up and strengthening local search. Through this learning mechanism, solutions with certain conditions can acquire higher adaptability with a higher probability by active learning. To enhance the global convergence speed and get better performance, this paper presents a WOA based on Lamarckian learning (WOALam) for solving high-dimensional function optimization problems. First, the population is initialized by good point set theory so that individuals can be evenly distributed in the solution space. Second, the upper confidence bound algorithm is used to calculate the development potential of the individual. Finally, based on the evolutionary theory of Lamarck, individuals with more development potentials are selected to perform the local enhanced search to improve the performance of the algorithm. The WOALam was compared with six variants of WOA on 44 benchmark functions. The experiments proved that the proposed algorithm can balance the global exploring ability and the exploiting ability well. It could obtain better results with fewer iterations and had good convergence speed and accuracy.

Renewable energy sources have provided a great contribution to global energy demand;However, their intermittent characteristics can cause sustainability and efficiency problems. To handle these, alternative systems are utilized. Among these, proton exchange membrane fuel cells (PEMFCs) stand out with their longer lifecycle, efficient, and costeffective features. However, their performance depends on operating conditions such as temperature, gas pressure, and membrane water content. These nonlinear features require instant and proper control for maximizing efficiency and longer working life. In this study, a whale optimization algorithm (WOA) based maximum power point tracking (MPPT) controller is utilized for a PEMFC system. To validate the proposed controller, the PEMFC system has been analyzed under changing conditions in the MATLAB/Simulink environment. The proposed method has been compared with the other MPPT methods. The results indicate that the proposed controller can provide accurate and fast MPPT performance, less power fluctuations, and higher production efficiency.& COPY;2023 Hydrogen Energy Publications LLC.

While handling problems of certain complex scene optimization, the whale optimization algorithm (WOA) algorithm may be affected by precocious convergence or local optimal solutions, resulting in the accuracy of low convergence and stagnation of dimensional population. To address these limitations, this research presents a whale optimization algorithm, which is established on pinhole imaging reverse learning and the golden sine strategy (LWOAG). Firstly, LWOAG employs pinhole imaging reverse learning to determine the reverse solution for optimal individual in the population, thereby improving the population's quality and algorithm convergence ability. Secondly, LWOAG utilizes the golden sine operator to perform greedy selection after the whale completes the search update, thus extending the search range and increasing the algorithm's global search capacity. Finally, after conducting comprehensive tests on 12 benchmark functions, LWOAG outperforms other enhanced whale optimization algorithms and intelligent algorithms in terms of accuracy and stability.

In this work, an attempt has been made to implement a nature-inspired stochastic evolutionary algorithm, namely whale optimization algorithm (WOA) for exploring optimum and practical solutions of load frequency control (LFC) problem in power system. The proposed WOA mimics the 'bubble-net feeding' strategy of 'humpback whales' in the oceans. The optimization technique is individually applied to a two-area thermal power plant and two-area hydro-thermal-gas power plant with AC-DC tie-line for fine-tuning of the controller parameters. The study further houses the consequences of frequency measurement and the dynamics of a phase-locked loop (PLL) with power system nonlinearities. To establish the efficacy of WOA, the obtained results are compared with results of success history based adaptive differential evolution (SHADE), krill herd algorithm (KHA), and some other well-known control algorithms. Finally, statistical analysis is performed to affirm robustness of the proposed WOA in LFC area.

Edge in image processing is considered as those pixels whose intensity value changes drastically and finding the object boundary is the main task of any edge detection technique. There have been various Ant Colony optimization (ACO), Particle Swarm optimization (PSO) based techniques that have been applied to solve edge detection problem, but most of them have not considered the noisy environment which in itself makes edge detection further more difficult task and the user-defined threshold approach doesn't always give desired results. The paper proposes a whale optimization algorithm (WOA) based edge detection technique with weighted fitness function including homogeneity, uniformity and average gradient magnitude as main factors for detecting the edges of additive gaussian noise images. The experiment results have shown that the proposed technique has performed better under noisy environment for conventional edge detectors: Sobel, Canny and ACO based technique for both objective criteria i.e. restored edge images and subjective criteria i.e. PSNR, Precision, Recall and F-measure.
