In order to improve the positioning accuracy of Underwater Wireless Sensor Network (UWSN) nodes, a zone-partitioning-based localization (ZPL) algorithm is proposed based on triangle geometry theory. The algorithm uses the triangular area formed between two anchor nodes and the node to be located, takes the ranging result as the side length, and iteratively refines the area according to the geometric theory to achieve position estimation. In the process of zone partitioning iterative positioning, linear algebra operations with low complexity are mainly used to improve the computational efficiency. After simulation comparison and analysis, the ZPL algorithm has more stable performance than the traditional positioning method, effectively increases the number of locatable nodes, and reduces the positioning error.
The command decision-making style of military commanders significantly impacts combat outcomes, yet existing research lacks objective quantitative analysis methods. To address this gap, this study establishes a quantitative index system through three behavioral dimensions derived from wargame replay data: terrain utilization, weapon deployment, and operational coordination. Utilizing hierarchical clustering algorithms, we achieve unsupervised classification of command decision-making styles. Three distinct tactical patterns are identified: terrain and firepower-dominant style, coordinated assault-efficient style, and balanced and steady style, each exhibiting marked disparities in tactical preferences. Corresponding counterstrategies are systematically proposed for each identified style. This research provides theoretical support for optimizing command decisions and developing wargame AI systems, demonstrating substantial potential for advancing intelligent military decision-making through data-driven style characterization.

In modern offensive and defensive operations, seizing air superiority is a decisive factor influencing the war situation. To achieve this, the Red Force must accurately predict the maneuver strategies of the Blue Force’s air defense fire units and formulate efficient joint reconnaissance-strike integrated operations. From the perspective of the Red Force, this paper constructs a multi-objective optimization model for the maneuver of the Blue Force’s air defense fire units under multiple constraints such as the air defense fire unit-target allocation and position deployment, to maximize the overall defensive capabilities and minimize the total maneuver time of air defense fire units. The ideal point method was employed to transform the multi-objective problem into a single-objective form, while equivalent simplification was applied to the nonlinear constraints in the model, thereby designing an efficient corresponding solution algorithm. With the aid of LINGO software for implementation, the Pareto optimal solution set under different weight combinations was ultimately obtained. Simulation results show that the weight coefficients determine the trade-off relationship of operational effectiveness between defense effectiveness and maneuver efficiency. The proposed model provides commanders with decision-making schemes oriented to different operational intents, enabling them to make scientific and rational decisions based on the battlefield situations.
Traditional dynamic scheduling methods for rail transit signals lack real-time dynamic optimization capabilities and exhibit rigid scheduling strategies, leading to prolonged average vehicle waiting times and increased average queue lengths after scheduling. To address this issue, this study designs a spatiotemporal evolution modeling and dynamic scheduling method for rail transit signals. The spatiotemporal evolution modeling provides accurate and real-time input data for dynamic scheduling of rail transit signals. A dueling double deep Q-network (D3QN) is designed by integrating double deep Q-networks (DDQN) and dueling deep Q-networks, leveraging decoupling and dueling structures to achieve dynamic scheduling of rail transit signals. Case study results demonstrate that the proposed method effectively enables dynamic scheduling of rail transit signals at experimental transportation hubs. The average vehicle waiting time using the proposed method remains below 250 seconds, and the average queue length is consistently around 20 meters, indicating high operational efficiency of the rail transit system under dynamic scheduling.

To address the challenges of rapid rumor dissemination and the tendency of traditional algorithms to fall into local optima in social networks, this paper proposes a real-time rumor refutation method based on a hybrid Shuffled Frog Leaping Algorithm and Particle Swarm Optimization (SFLA-PSO). This approach integrates the clustering cooperative local search capability of SFLA with the fast global convergence advantage of PSO. Firstly, a rumor dissemination model incorporating users' social ties and trust degrees is constructed. Users are categorized into different age groups, and differentiated modeling strategies (SFLA or PSO) are applied according to their cognitive characteristics. Secondly, the SFLA-PSO hybrid optimization algorithm is designed to dynamically update user trust levels through local deep search and global information interaction, thereby efficiently blocking rumor propagation. Simulation results demonstrate that, compared with standalone SFLA and PSO algorithms, the proposed hybrid algorithm exhibits significant advantages in convergence speed and computational efficiency. It can guide user cognition towards the truth more rapidly and comprehensively, effectively curbing the spread of rumors.
The intelligent upgrade of network-centric operation and maintenance systems relies on the efficient deployment of large language models (LLMs). However, resource-constrained edge environments and dynamic adversarial threats pose dual challenges to traditional fine-tuning methods. Existing approaches often address computational efficiency and model security in isolation, leading to lightweight strategies that compromise defense capabilities or security mechanisms that exacerbate resource consumption. To resolve this conflict, this paper proposes a Lightweight and Secure Co-Tuning Framework (LST-Framework) that achieves multi-objective optimization through dynamic parameter sparsification and hierarchical defense mechanisms. The method first constructs a task-sensitive dynamic parameter activation strategy, identifying redundant weights via spectral analysis of the Hessian matrix to establish sparse fine-tuning paths, reducing computational complexity to 23% of full-parameter fine-tuning. Simultaneously, a three-tier defense system—comprising adversarial input detection, lightweight gradient masking, and output uncertainty verification—enhances robustness against white-box attacks with only an 8% increase in inference overhead. Experiments on typical network operation datasets (e.g., CIC-IDS2017) demonstrate that the LST framework maintains 98.3% original task accuracy while compressing memory usage by 51.7%, reducing inference latency by 32.4%, and successfully resisting 94.6% of PGD-targeted attacks. This work provides theoretical and technical foundations for deploying large models in low-resource, high-security scenarios such as 5G core networks and industrial IoT.
