The study aims to address critical challenges in network security, particularly the limitations of traditional intrusion detection systems (IDS) in terms of adaptability, detection precision, and high false positive rates in dynamic network environments. A novel hybrid IDS model integrating the Flower Pollination algorithm (FPA), cheetah optimization algorithm (COA), and Artificial Neural Networks (ANN) is proposed to enhance detection accuracy, reduce false positives, and optimize feature selection, anomaly detection, and rule adaptation. The hybrid FPA-COA-ANN model combines the optimization capabilities of FPA and COA with the predictive power of ANN. The model was evaluated using five benchmark datasets-CICIDS-2017, TII-SSRC, Lu-flow, NSL-KDD, and WSN-DS. Key performance metrics were analysed to assess the model's effectiveness in detecting malicious activities in complex network traffic patterns. The hybrid model demonstrated superior performance compared to existing IDS approaches. It achieved accuracy rates of 0.99 on CICIDS-2017, 1.00 on TII-SSRC, 1.00 on Lu-flow, 0.99 on NSL-KDD, and 0.93 on WSN-DS. The results highlight significant improvements in detection precision and adaptability, alongside a reduction in false positive rates, showcasing the model's robustness and scalability for real-time threat detection. The proposed hybrid FPA-COA-ANN model effectively mitigates the limitations of traditional IDS by offering a robust, scalable, and efficient solution for real-time network threat detection. Its high accuracy and adaptability across diverse benchmark datasets underscore its potential as a critical tool for enhancing cybersecurity defences in dynamic and complex environments.

This paper introduces and investigates an enhanced Partial Reinforcement optimizationalgorithm (E-PROA), a novel evolutionary algorithm inspired by partial reinforcement theory to efficiently solve complex engineering optimization problems. The proposed algorithm combines the Partial Reinforcement optimizationalgorithm (PROA) with a quasi-oppositional learning approach to improve the performance of the pure PROA. The E-PROA was applied to five distinct engineering design components: speed reducer design, step-cone pulley weight optimization, economic optimization of cantilever beams, coupling with bolted rim optimization, and vehicle suspension arm optimization problems. An artificial neural network as a metamodeling approach is used to obtain equations for shape optimization. Comparative analyses with other benchmark algorithms, such as the ship rescue optimizationalgorithm, mountain gazelle optimizer, and cheetah optimization algorithm, demonstrated the superior performance of E-PROA in terms of convergence rate, solution quality, and computational efficiency. The results indicate that E-PROA holds excellent promise as a technique for addressing complex engineering optimization problems.

As a central participant and important leader in the global climate governance system, China is facing the urgent need to predict and regulate the price of carbon emissions to promote the sound development of its carbon market. In this article, a rolling prediction model based on Least Absolute Shrinkage and Selection Operator-cheetah optimization algorithm-extreme gradient boosting (Lasso-COA-XGBoost) carbon price decomposition integration is proposed to address the defects of low prediction accuracy and insufficient model stability of a single machine learning model in the carbon price prediction problem. During the modeling process, the adaptive Lasso method is first employed to select factors from 15 primary indicators of carbon prices, identifying the most important influencing factors. Next, the COA-XGBoost model is built and the parameters of the XGBoost model are optimized using the COA algorithm. Finally, the complete ensemble empirical Mode Decomposition with adaptive noise (CEEMDAM) method is utilized to decompose the residual sequence of the COA-XGBoost model and reconstruct it into high-frequency and low-frequency components. Appropriate frequency models are applied to achieve error correction, thereby constructing the combined Lasso-COA-XGBoost-CEEMDAN model. To further enhance the predictive accuracy and practicality of the model, a rolling time window is introduced for forecasting in the Hubei and Guangzhou carbon emission trading markets, ensuring that the forecasting model can adapt to market changes in real-time. The experimental results show that, taking the carbon price prediction in Hubei as an example, the proposed hybrid model has a significant improvement in prediction accuracy compared with the comparison model (XGBoost model): the RMSE is improved by 99.9987%, the MAE is improved by 99.9039%, the MAPE is improved by 99.9960%, and the R-2 is improved by 0.2004%, and the advantages of this hybrid model are also verified in other experiments.

Efficiently managing building heating loads (HL) is essential for maximizing energy use. and reducing environmental impact. This study explores the application of decision tree (DT)-based patterns in predicting HL, coupled with two innovative optimizers, the cheetah optimization algorithm (COA) and Smell Agent optimization (SAO). The research leverages the flexibility and interpretability of DT, a machine learning framework, to framework complex relationships between various building parameters and HL. DTs excel at capturing non-linear relationships, making them suitable for such applications. Incorporating the COA and SAO optimizers introduces an element of intelligence into the framework process. Preliminary outcomes indicate that the combination of DT with COA and SAO optimizers significantly improves the accuracy of HL prediction. This enhancement has promising implications for building management systems, allowing for more precise control of heating systems and energy consumption optimization. Significantly, the hybrid DT+SAO (DTSA) framework delivers reliable outcomes for HL prediction, boasting an impressive correlation coefficient (R2) value of 0.996 as well as a low root mean squared error (RMSE) value of 0.657. This study advances the broader field of energy-efficient building regulation by showcasing the potential of machine learning frameworks and intelligent optimizationalgorithms for accurately forecasting HL.

People leading a modern lifestyle often experience varicose veins, commonly attributed to factors associated with work and diet, such as prolonged periods of standing or excess weight. These disorders include elevated blood pressure in the lower extremities, especially the legs. An often-researched metric associated with these illnesses is the Vascular Clinical Severity Score (VCSS), which is connected to discomfort and skin discolorations. However, yoga appears to be a viable way to prevent and manage these problems, significantly lessening the negative consequences of varicose veins. The investigation of yoga's effect on VCSS in this study uses a novel strategy combining machine learning with the Extra Tree Classification (ETC), which is improved by the cheetah Optimizer (CO) and Black Widow Optimizer (BWO). In this study, the ETC model was combined with previously mentioned optimizers, and two models were amalgamated, referred to as ETBW and ETCO. Through the evaluation of the performance of these models, it was discerned that the accuracy measure for prediction was associated with the ETCO model in the context of VCSS. By revealing subtle correlations between yoga treatments and VCSS results, this multidisciplinary approach seeks to provide a thorough knowledge of preventative and control processes. This research advances the understanding of vascular health by correlating yoga interventions with VCSS outcomes using machine learning and optimizationalgorithms. By enhancing predictive accuracy, it promotes multidisciplinary collaboration, personalized medicine, and innovation in healthcare, promising improved patient care and outcomes in varicose vein management.

This study explores the application of machine learning (ML) techniques to predict the optimum moisture content (OMC) of soil-stabilizer combinations. OMC represents the moisture level where soil achieves peak compaction and strength in conjunction with a stabilizer, playing a vital role in attaining desired engineering properties in soil stabilization endeavors. Employing the adaptive neuro-fuzzy inference system (ANFIS) as a robust ML tool, this research endeavors to formulate intricate and accurate models. These models forge connections between OMC and many intrinsic soil properties, including particle-size linear shrinkage, plasticity, distribution, and the nature and quantity of stabilizing additives. A diverse dataset is curated to ascertain the responsiveness of OMC to variations in influential factors, encompassing distinct soil types and previously documented results from stabilization tests. In an endeavor to enhance model precision, this study integrates two meta-heuristic algorithms: the cheetah optimization algorithm (CO) and the equilibrium slime mould algorithm (ESM). By synergistically leveraging these algorithms, the accuracy of the models is fortified. Rigorous validation ensues through an analysis of OMC\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$OMC$$\end{document} samples drawn from diverse soil types obtained from historical stabilization test outcomes. The study unveils three notable models: ANCO (ANFIS + CO), ANES (ANFIS + ESM), and an independent ANFIS model.
