标题： Control Strategies for Recommendation Systems in Social Networks

摘要： 引入了一个闭环控制模型，用于分析推荐系统对社交网络中意见动态的影响。 核心贡献是开发和形式化了无模型和有模型的推荐系统设计方法，通过扩展Friedkin-Johnsen（FJ）模型，将社交互动的动力学整合到网络中。 比较分析和数值模拟证明了所提出的控制策略在最大化用户参与度方面的有效性，以及其在影响意见形成过程中的潜力。 显示英文摘要

摘要： A closed-loop control model to analyze the impact of recommendation systems on opinion dynamics within social networks is introduced. The core contribution is the development and formalization of model-free and model-based approaches to recommendation system design, integrating the dynamics of social interactions within networks via an extension of the Friedkin-Johnsen (FJ) model. Comparative analysis and numerical simulations demonstrate the effectiveness of the proposed control strategies in maximizing user engagement and their potential for influencing opinion formation processes.
