“…Among them, the support vector machine (SVM) [8] , association rule analysis [9] , cluster analysis [10] and other algorithms in descriptive mining can deeply mine the changing trend of construction cost, accurately estimate the relationship between construction cost and influencing factors and have strong generalization ability, which becomes the main tool of construction cost prediction. For example, Xu et al [11] used sparrow search algorithm and SVM to predict the project cost, and estimated the project cost by taking the actual project as a power grid case. Miao et al [12] put forward a rapid prediction system of engineering cost based on SVM model, which can achieve the purpose of rapid prediction of engineering cost through simple and interactive input of engineering features.…”

Cost estimation in construction engineering is a crucial topic of study. Low precision in construction engineering cost prediction results from traditional models' inability to adequately capture the evolving trend of construction engineering costs. As a result, a descriptive data mining-based cost prediction model for construction engineering is suggested. The database of engineering costs is first built using several characteristic indices, and the aberrant data are found and filtered using the K-means clustering approach. Second, the mathematical model is established, and its solution is carried out using the LSSVM. Finally, the model is optimized using the PSO technique. The experimental results demonstrate that, in comparison to the conventional engineering cost prediction models, our model's predicted value of the single cost is the closest to the actual cost of one party, and the predicted difference is all within 30 yuan/m2. This finding has significant implications for engineering investment decisions because it can achieve higher accuracy and stability in engineering cost prediction.

Pillar stability is an important condition for safe work in room-and-pillar mines. The instability of pillars will lead to large-scale collapse hazards, and the accurate estimation of induced stresses at different positions in the pillar is helpful for pillar design and guaranteeing pillar stability. There are many modeling methods to design pillars and evaluate their stability, including empirical and numerical method. However, empirical methods are difficult to be applied to places other than the original environmental characteristics, and numerical methods often simplify the boundary conditions and material properties, which cannot guarantee the stability of the design. Currently, machine learning (ML) algorithms have been successfully applied to pillar stability assessment with higher accuracy. Thus, the study adopted a back-propagation neural network (BPNN) and five elements including the sparrow search algorithm (SSA), gray wolf optimizer (GWO), butterfly optimization algorithm (BOA), tunicate swarm algorithm (TSA), and multi-verse optimizer (MVO). Combining metaheuristic algorithms, five hybrid models were developed to predict the induced stress within the pillar. The weight and threshold of the BPNN model are optimized by metaheuristic algorithms, in which the mean absolute error (MAE) is utilized as the fitness function. A database containing 149 data samples was established, where the input variables were the angle of goafline (A), depth of the working coal seam (H), specific gravity (G), distance of the point from the center of the pillar (C), and distance of the point from goafline (D), and the output variable was the induced stress. Furthermore, the predictive performance of the proposed model is evaluated by five metrics, namely coefficient of determination (R2), root mean squared error (RMSE), variance accounted for (VAF), mean absolute error (MAE), and mean absolute percentage error (MAPE). The results showed that the five hybrid models developed have good prediction performance, especially the GWO-BPNN model performed the best (Training set: R2 = 0.9991, RMSE = 0.1535, VAF = 99.91, MAE = 0.0884, MAPE = 0.6107; Test set: R2 = 0.9983, RMSE = 0.1783, VAF = 99.83, MAE = 0.1230, MAPE = 0.9253).

This paper reviews the latest versions and applications of sparrow search algorithm (SSA). It is a recent swarm-based algorithm proposed in 2020 rapidly grew due to its simple and optimistic features. SSA is inspired by the sparrow living style of foraging and the anti-predation behavior of sparrows. Since its establishment, it has been utilized for a plethora of optimization problems in different research topics, such as mechanical engineering, electrical engineering, civil engineering, power systems, industrial engineering, image processing, networking, environment, robotics, planing and scheduling, and healthcare. Initially, the growth of SSA and its theoretical features are highlighted in terms of the number of published articles, citations, topics covered, etc. After that, the different extended versions of SSA are reviewed, where the main variations of SSA are produced to avoid premature convergence and to boost the diversity aspects. These extended versions are modifications and hybridization summarized with more focus on the motivations behind establishing these versions. Multi-objective SSA is also presented as another version to deal with Multi-objective optimization problems. The critical analysis of the main research gaps in the convergence behaviour of SSA is discussed. Finally, the conclusion and the possible future expansions are recommended based on the research works accomplished in the literature.
