Based on the contradiction between the increasing power demand and the low capacity of the traditional direct current (DC) transmission system, this study innovatively combines the swarm intelligence optimization algorithm with power transmission and storage, and establishes a flexible DC transmission system model based on the swarm intelligence optimization algorithm. The study also analyzes the difference between the optimized capacity configuration of flexible DC transmission system and the traditional transmission system under different factors. The research results show that the transmission mode has become an important factor affecting the capacity allocation of flexible DC transmission system. The transmission medium and transmission cable type also have an impact on the capacity allocation of flexible DC transmission system. Optimizing power transmission mode, changing transmission medium and whether to add the swarm intelligence optimization algorithm are of far-reaching significance for improving the capacity allocation of flexible DC transmission system.

Matrix metalloproteinase-12 (MMP-12) is an attractive therapeutic target for drug design and discovery for many human conditions. In this study, six swarm intelligence optimization algorithms were applied to optimize the parameters of the model generated using the LibSVM toolkit in MATLAB to identify potential MMP-12 inhibitors (MMP-12is);six types of optimized support vector machine (SVM) models were established. The highest prediction accuracy obtained was 98.89 %, which was equivalent to the effect of the optimal "RF+opt" model. All six models passed the Y-randomization test and showed excellent performance with reliable results. Virtual screening identified 371 molecules with a predictive probability score greater than 0.9. The optimized SVM models, in addition to "RF+opt" and "SVM2" models, were combined to establish a consistency evaluation system. Our results revealed six non-toxic potential MMP-12is. This process provides a strong theoretical basis for the design, synthesis, and development of novel drugs targeting MMP-12.

The multi-unmanned aerial vehicle (UAV) task allocation method has shortcomings such as long flight distance and long algorithm initialization time. In response to these problems, this paper proposes a UAV task allocation method based on swarm intelligence optimization algorithm (SIOA). The algorithm first compares the relationship between the number of UAVs and mission points when UAV is performing a task, and then introduces the idea of gradient descent to reduce the flying distance of UAV. Experimental results show that the SIOA method can effectively reduce the initialization time, shorten search distance of the UAV and the time UAV complete the task, and effectively solve the problem of high algorithm complexity.

After the human society entered the network age, with the continuous development of information technology, the amount of data generated and collected in various production activities continued to increase, which prompted a new change in the field of machine learning and data mining research. swarm intelligence optimization algorithm is an important research direction in the field of evolutionary computing. Based on the theoretical research of the swarm intelligence optimization algorithm, this paper studies and analyzes the construction of the stomatology development review system based on the swarm intelligence optimization algorithm, and uses its optimization performance to deal with the feature selection application of medical data sets.

The accurate calculation of the height of fractured water-conducting zone (FWCZ) is of great significance for mine optimization design, water disaster prevention, and safety production of the coal mines. In this article, a height-prediction model of FWCZ based on extreme learning machine (ELM) is proposed. To address the issues of low prediction accuracy and challenging parameter optimization, we optimized the ELM model using the gray-wolf optimization algorithm (GOA), whale optimization algorithm (WOA), and salp optimization algorithm (SOA). These optimization algorithms mitigate the issues of slow convergence, poor stability, and local optimality associated with traditional neural networks. The mining depth, mining height, overburden strata structure, working face length, and coal seam dip angle are selected as the main controlling factors for the height of FWCZ. A total of 42 fields-measured samples are collected and divided into 2 subsets for training and validating with a ratio of 36/6. The prediction capability of GOA-ELM, WOA-ELM, and SOA-ELM models are evaluated and compared, and the results show that the calculation results of the three models are optimized compared with the ELM model. The prediction capability of GOA and WOA are similar, while the prediction results of SOA-ELM are better than the other two models, and the relative errors of the test sets are all less than 10%. Therefore, the SOA-ELM model is finally applied to predict the height of FWCZ formed after the mining of No.15 coal seam in Xinjian Coal Mine. Finally, we verified the prediction results using measured data from the borehole television detection instrument, which showed good consistency. This provides further evidence of the effectiveness of the swarm intelligence optimization algorithm in predicting the height of FWCZ.

In the context of traditional energy shortage and climate warming, the development of solar energy, as a clean and renewable energy, is crucial. As an effective way to utilize solar energy resources, photovoltaic (PV) power generation technology has been widely used around the world. Using remote sensing images to extract PV panel information, including location, area, has a positive effect on understanding the development status, planning and construction of regional PV new energy. In this study, a semantic segmentation network called HCT-Net, combined with the hybrid neural networks and the swarm intelligence optimization algorithms, is designed to segment solar PV panels from remote sensing images automatically and accurately. To address the problem of inconsistent segmentation within PV regions, a hybrid encoder, which combines a convolutional neural network and a Transformer, is designed to extract local features with rich detail information and global features with global context dependencies, resulting in enhanced feature representations. The foreground relation module is designed to solve the problem of mis-segmentation of the background into PVs. This module strengthens the model's focus on the target object and suppresses the feature representations of non-PVs by explicitly learning the similarity relationship between the global PV feature representation and the feature representations of other objects, and by adaptively assigning weights according to the similarity. The swarm intelligence optimization algorithm is applied to adjust the learning rate and the balance coefficient of the composite loss function of HCT-Net during training. Experimental results show that compared with the current mainstream semantic segmentation network, the method in this study effectively alleviates the problem of inconsistent segmentation within PV regions and mis-segmentation and has advantages in the complete and accurate extraction of PV panels.

Global ionospheric total electron content (TEC) map prediction is important for improving the accuracy of global navigation satellite systems. There are two main issues with the current TEC prediction: (1) The deep learning models used for TEC prediction are mainly designed using a stacked structure. When stacking multiple layers, the input data will undergo continuous multi-layer convolution operations, leading to the loss of fine-grained features and the degradation of model performance;(2) The model optimization methods for TEC prediction are relatively outdated, mainly using manual optimization or grid search methods. To address these two issues, an automatic framework for global TEC map prediction and optimization is proposed, named as CGAOA-STRA-BiConvLSTM. It includes a global TEC map prediction model, STRA-BiConvLSTM, which can simultaneously extract both coarse-grained and fine-grained spatiotemporal features. It also contains an optimization algorithm, CGAOA, to optimize the model. We first experimentally verified the effectiveness of CGAOA. Then, the effectiveness of STRA-BiConvLSTM was verified through ablation experiments. Finally, we conducted comparative experiments from multiple perspectives between our framework and 5 mainstream methods: C1PG, C2PG, ConvLSTM, ConvGRU, and ED-ConvLSTM. The results show that in all cases, the proposed CGAOA-STRA-BiConvLSTM outperforms the comparative models.
