In recent research, metaheuristic strategies stand out as powerful tools for complex optimization, capturing widespread attention. This study proposes the Educational Competition Optimizer (ECO), an algorithm created diverse optimization tasks. ECO draws inspiration from competitive dynamics observed in real-world educational resource allocation scenarios, harnessing this principle to refine its search process. To further boost efficiency, divides iterative process into three distinct phases: elementary, middle, and high school. Through stepwise approach, gradually narrows down pool of potential solutions, mirroring gradual competition witnessed within systems. strategic approach ensures a smooth resourceful transition between ECO's exploration exploitation phases. The results indicate that attains peak performance when configured with population size 40. Notably, algorithm's efficacy does not exhibit strictly linear correlation size. comprehensively evaluate effectiveness convergence characteristics, we conducted rigorous comparative analysis, comparing against nine state-of-the-art algorithms. remarkable success efficiently addressing problems underscores applicability across domains. additional resources open-source code proposed can be accessed at https://aliasgharheidari.com/ECO.html https://github.com/junbolian/ECO.

Abstract Crack formation is a common phenomenon in engineering structures, which can cause serious damage to the safety and health of these structures. An important method ensuring engineered structures prompt detection cracks. Image threshold segmentation based on machine vision crucial technology for crack detection. Threshold separate area from background, providing convenience more accurate measurement evaluation condition location. The cracks complex scenes challenging task, this goal be achieved by means multilevel thresholding. arithmetic-geometric divergence combines advantages arithmetic mean geometric probability measures, enabling precise capture local features an image processing. In paper, thresholding minimum proposed. To address issue time complexity thresholding, enhanced particle swarm optimization algorithm with stochastic perturbation detection, criterion function adaptively determine thresholds according distribution characteristics pixel values image. proposed increase diversity candidate solutions enhance global convergence performance algorithm. compared seven state-of-the-art methods several metrics, including RMSE, PSNR, SSIM, FSIM, computation time. experimental results show that outperforms competing terms metrics.

Microscopic image examination is essential for medical diagnostics to identify anomalies using cell counts based on morphology. Sickle Cell Disease (SCD) an inherited blood condition characterized by defective hemoglobin, leading severe anemia and complications. Detecting sickle cells in smears essential, but the presence of White (WBCs) platelets often leads miscounting as they are classified incorrectly red (RBCs). This study proposed approach segmenting WBCs resembling human color recognition process differentiate regions accurate identification. First, RGB space converted RG chromaticity locate with high pixel chromatic variance. Parametric segmentation applied images appropriate channel probability distribution values. The optimal threshold values have been determined Particle Swarm Optimization (PSO) dynamically narrowing search obtained through manual experimentation ranging from 0.001 1. systematic effectively identifies segments WBCs, ensuring that overlapping accurately segmented. Compared state-of-the-art techniques, achieved accuracy 96.32 %, 96.97% sensitivity, 96.96 % precision 97.46% F- score pixel-wise platelets.
